Solve / Crumble / Toss

A colleague of mine told me about this activity, and it has been a lot of fun for the class.

The Description

The basics are that the students are in pairs and do one problem on a whiteboard.  I check all their answers.  Then they crumble that problem up and throw it across the room. When I say stop, they all stop throwing, and pick up a new problem.  They uncrumble their new problem, do it on the whiteboard, and the process starts over again.

Each problem has a number, and it’s important that each group puts the number of the problem on the whiteboard, so I can know which problem they did when they hold up their whiteboards.  I have the answer key in front of me so I can quickly check if they are right or wrong.

I generally use about 8 different problems.  There is a chance that students will pick up a problem they have already done, so if that happens, I just tell them to pick up a new one.  At the end of the activity I like to give them a worksheet that has all of the problems from the activity on it.

I use colored paper to make sure that only the problems are getting thrown.  I use two colors, and make one color for easier problems, and the other color for more challenging problems.

The Advice

– I let the student throw paper back and forth, which gets hectic, but they love it.  If you want a more controlled scenario, only allow them one throw.

– Make it clear – they must stop throwing exactly when you say “Stop”, and cannot throw until you say “Throw”.

– Use colored paper, and make sure no white paper is thrown.

– A full sheet of paper can be thrown to hard, so be sure to use a half sheet for each problem.  Some students may try to crumble a couple of problems together to make a larger ball – big time no no.

– I arrange the desks so that half of the class is facing the other half of the class.  Let the students know the back row is the safest place.

– The problems can be hard to read when crumbled a lot, so use a large font.

Here is the one I did for a review on Inequalities in algebra 1.

The Update 1

– Yesterday (at the advice of a colleague) at the end of class I stood in front of the recycle bin and told the students to all throw their papers at me.  It has two great benefits:  The students love it.  It makes cleanup easier because all the paper ends up in the same general area.

– I like to handout fresh problems (meaning problems on paper that has not been crumbled) for the first round of each class because the problems get harder to read the more the paper is crumbled.  It also allows me to intentally differentiate by ensuring that high achieving students get the more difficult problems.

The Disciplined Discipline Discussion

The discipline discussions I have with students are fundamental to the success of my  Long / Short Forms.   I’m going to keep coming back to this topic, but here are some of the important things I try to do when I talk to a student after class who received a Long / Short Form.  By the way, for most students this converstion is straightforward, but for the most disrputive students it can be a bit tricky, so the details of it become very important.

The key to discipline discussions is to remember that the goal of them is not to convince the student that you are right and they are wrong.  The goal is for you to let the student know why they received the Long / Short form, and why that behavior is not acceptable to you.  This goal allows you to stay focused on what is important, and also avoid getting into an argument.  Never get into a back and forth with a student on why they received the discipline.

Strike a positive tone.   If the student appears upset, I will say something like this:  “Don’t think of this form as a ‘I hate you, shut up, stop talking’, but rather think of this as ‘Mr. Miller wants me to be successful, and thinks that my behavior at this moment is not allowing me to be at my full potential'”.   Remind the student that you want them in the class, you enjoy their personality, but it is this or that behavior that you will not accept.    The behavior is separate from the person.  Because don’t forget – you’re not mad at them.

Here’s the basic scenario:  Tell the student why they received the Long / Short Form.  Ask them if they understand, and if they believe you are being reasonable.  Hear what they say.  If they agree, then it’s all good.  If they argue about why they should not have received the form, or how it was not their fault, then repeat back their point to them – tell them why it seems like a reasonable idea, but you can not have them do that for this or that reason.  Conversation on topic ends.  Do not get into a debate about what happened or what the rules are.  If at the end of the discussion the student does not agree with you, that is fine.  They just need to know why you gave them the form and that they should expect the form again if they repeat the behavior in the future.

Oh yeah, and if the student is correct, and you did make a mistake – maybe you gave them a form too quickly because you were angry for some reason, here’s what you do:  Apologize.

Math Hospital Remix

I decided to remix the Math Hospital.  All the steps are the same that I outline in my original post about the activity, which can be found here.   The only difference is the handout, where I now embed the problem that we are fixing into the worksheet.  This allows students to circle and point to the things that they like, or believe are right or wrong.  I also have them fix the patient (correct the problem) right there on the worksheet.

MathHospital2The Advice

Sell the hospital.  To have them quite down, tell them the patient is sleeping.  If correcting the problem becomes homework, say “I want to have this patient looking healthy by tomorrow”.  And so forth…

I’ve done this in groups of four, but typically it is done individually.

My Best Days Are My Happy Days

It occurred to me that my best days teaching are often my happiest days.  And the cause and effect there is important – it’s not my best day that caused me to be happy, it’s that fact that I’m the happy, which caused me to have my best day.  Classroom management can often hinge on how energized and happy we are.  So as far as preparation goes, Tolle’s The Power of Now becomes just as important to read as Marzano’s Classroom Management That Works.

This post thus far might make it sound like I’m bipolar, coming to school depressed some days, happy others.  But what I’m really talking about here is the difference between being in a good mood, and being in a great mood.  The difference between having disruptive students leave you frustrated, and having them not affect you negativiely.  The difference between going through the motions, and pausing to appreciate the moments.  This corner of classroom management takes us deep into self-reflection, but it is a place we need to go into if we are to be the teacher we want to be.

I have written about some of the things I do to stay positive and energized here and here.

Congruent Triangles Worksheet

The Overview

Here are two worksheets I created for triangle congruency – one of them is focused soley on SSS, the other on SAS.  Both worksheets begin with two problems where all the information necessary is given in the diagram, then they have two problems where the students need to identify a piece of inherent information, and then two problems where they need to intrepret both inherent and given information.  Then the last three problems are a combination of those.

The Method:

I first put the worksheet into Keynote so I can setup my timers and have my board look like their worksheet.  After that, this is my general recipe.

  1. I do the first problem on the board myself.
  2. I put up a 1 – minute timer and have the students work on the second problem.
  3. After that minute is done, I have them share with their pair share partner.
  4. I pull a popsickle stick and call on one group to come to the board and work the problem.
  5. I then repeat this process again – where I do problem 3, they do 4.  I do 5, they do 6.  Then I have them finish the worksheet on their own.

The Goods:

SAS

Dig a Hole to China

The Description:

Show them this website and ask them if they can figure out what it is all about:

This site shows the exact opposite side of the earth from anywhere on earth.  So if you dug a hole straight down through the center of the earth, this site shows you were you would end up.  Every student in my class had heard the old saying about “dig a hole to China”, where it is believed that if you dug a hole straight through the earth, you would end up in China.  Apparently it’s not true, you would end up in the middle of the Atlantic.  Students will definitely ask you to find where you would need to start digging if you wanted to end up in China (Argentina).

That is about all you need to pose the question “If you were to dig a hole to China, how deep would the hole be?”

I give the students the circumference of the earth.   This lesson is teaching them to find the radius from the circumference.

C = 2(pi)r

The Advice:

At the end of class come back to the fact that if you give them radius, they would be able to give you diameter and circumference.  If you give them circumference, they should be able to give you radius and diameter.

The Goods:

I do not give any handouts.

Long and Short Forms – A Discipline Overview

Before I describe these forms I want to restate that classroom management is driven mainly by content (engaging lesson plans), and secondly by making students feel welcomed and appreciated, and keeping ourselves positive and energized.    For me personally, if classroom management ever became a process of making a bunch of rules, and figuring out how to enforce them, then I would probably quit teaching because my heart is not into it.  But that being said, a discipline structure is needed and this post is the beginnings of a description of mine.

The Description:

My main tools for handing out discipline in my class are Long Forms and Short Forms.  These forms generally take the place of referrals and detentions.  The Short Form has entirely eliminated my need for detentions, and the Long Form is generally used in replacement of referrals.

I save all forms in class folders.  Students who are behavior problems generally get their own folder.  This is great for me and administrators, as I can bring the folder to parent / teacher conferences, and provide it to administrators as a record of student behavior in class.

Here are brief descriptions of each:

Short Forms (Student Behavior Reflection):  I give students Short forms for minor distractions.  When they get a short form they must stop whatever they are doing and fill it out immediately.  They are not allowed to protest a short form, and if they feel they receieved it in error, they must write that in the form.  At the bottom of the form there is a place for their signature and mine, which I will only do after class.  Thus after class I quickly touch base with each student and let them know why I gave it to them.  I also be sure to listen to their explanations of why they acted the way they did, or why they thought they didn’t deserve it.

Long Forms (Student Self-Diagnostic Referral):  Long Forms are for more serious infractions.  Some examples would include defiance, and name calling.  I also do not give two short forms to the same student on the same day.  Thus if a student already has a short form, then any distraction could result in a Long Form.

If a student gets a Long Form, they must leave the classroom to fill it out, and they must come back into the classroom when they are finished.  The Long Form also has a place for Parent / Vice Principal signature.   I do not always require the student to get those signatures.

The Advice:

Students who recieve these forms must stay after class and talk to me.  These conversations are incredibly important for a lot of reasons – diffuse any possible hostility, help further explain to student why certain behaviors are not acceptable, and so forth.  I will write a post all about the importance of these conversations , and how I approach them, at a later date.  (see update below)

If students refuse to stay after class to talk, then it is an immediate referral.

I added that little box at the bottom of each form this year.  I check the box if I think the form did not change student behavior.

The Goods:

LongForm

The Update:

Here are some thoughts on discipline discussion you should be having with students who receive these forms.

Straw Bridge Challenge

This year I used the Straw Bridge Challenge on the first day of school as an ice breaker, an introduction to engineering, and a way to get their minds engaged.  There are several versions of this activity around, I used the one that was given to me by an engineer at Lockheed.

The Description

Goal:  Build a bridge that can span a 12″ gap and hold a 1lb weight for 5 seconds.

Materials:  20 straws.  24 inches of tape.  That’s it.

Design Specifications:  

  1. The bridge must span a 12-inch gap between two desks.
  2. The bridge must be free standing, meaning it may not be taped to the desk
  3. The 1lb weight is a full 16oz water bottle.
  4. The bridge must support the weight for at least 5 seconds without the bottle falling over and without the assistance of humans.
  5. Only supplied materials may be used.  Nothing else.

The Advice

My first class struggled the most with it because I had no examples to show.  I was able to use my 1st classes bridges as examples for the rest of my classes, and the bridges got progressively better as the day went on.  You may want to have a couple examples available for the students to look at.  Although expect the a lot of the groups to try to copy the examples, rather than create something new.

Get it Wrong

Yesterday I was teaching solving two-step equations in algebra, and I gave them a worksheet with 5 problems on it.  We did two problems in my teach/pair/share format.   Then I asked them to trade papers with their partner, and do problem #5 on their partners paper.  The only catch was – they had to do it wrong.  They needed to make a mistake.  Problem #5 looked like this: 2x + 8 = 16.

I told them not to get it obviously wrong, no dividing both sides randomly by 113. But to try to do a common mistake that either they have made in the past, or something that might happen.

It was pretty funny for the class as I walked around and looked at each persons paper and said something like “That’s definitely not right.  Great Job!”.  After 5 minutes I had students trade papers again and correct the mistake their partner made.

Students will not know why you are having them do this, so hit them with something like this–> Important Speech:  The reason we are doing this is because when you are trying to get something wrong, you inevitably have to think about how to get it right, because you have to know what is right in order to avoid it.   So getting a problem wrong is another way to think about how to get a problem right.  The added benefit is that by doing a problem incorrectly, you also get to expose yourself to the most mistakes that are made, so then you won’t make them in the future.  And lastly, you even get to correct someone elses mistake, which even further improves your understanding of a problem.

After I said something similar to above, most the class had an “oh yeah, that makes sense” look in their eyes.

The Advice:

I would be careful to use this technique on the first day I introduce a topic.  I am a bit concerned how effective it would be if half the class has no idea how to do it the right way.  I have only used it during the 2nd or 3rd day (55 minute classes) we look at a topic.

What I Do When I Have A Bad Day

I definitely think an important part of classroom management is learning how to manage ourselves.  How to put the things that happen in our classes into perspective, and keep ourselves focused, happy, and energized.  And how to keep ourselves from not feeling tired, regretful, or hopeless.  We have to keep ourselves fresh and away from negativity, which is easier said than done.  Especially on those days where it’s not working for us.  Those days where a disruptive student got the best of us, and has us feeling outmatched.  So I’ll just tell you that when I have one of those days –  I always recite the following quote to myself:

“Finish each day and be done with it, you have done what you could.  Blunders and absurdities no doubt crept in; forget them as soon as you can.  Tomorrow is a new day.  Begin it well and serenely and with too high a spirit to be cumbered with your old nonsense.” – Ralph Waldo Emerson

I have it reserved to memory and recommend you do too.  It cheers me up and gives me energy to face each day anew.  For me, it is exactly what I need to hear at that moment.  I won’t talk about what else it means to me, I’ll let it mean to you whatever you want it to.

Another thing that helped me tough days I wrote about here.  If you are having issues with a couple students who are really frustrating you, I recommend reading it.  It is a technique I use to reframe my thinking on problem students into a positive and productive mindset.
