A Fun Way to Check Multiplication Problems
Middle school students still like those fun seasonal activities! Many years ago (I have no idea how many) I used this pattern coloring activity with my middle-schoolers. I don't remember where the idea came from, and I had even forgotten that I ever used it! However, I was looking through an old "November" file to find some ideas for a fun activity for a sub day, and found the tracers and examples in my file.
Once I found it, I DID remember that the kids used to really enjoy this activity. They had fun creating the patterns and deciding what colors to include. So, I gathered materials (graph paper, tracers, colored pencils, thin black markers, construction paper) and left them for the sub, with these directions:
Using Your Time Effectively and Efficiently
Having the perfectly-run math class....that's been my goal, year after year. Somehow, in middle school, it has consistently tried to evade me!
In other posts, I've shared that I taught elementary math for years, and always had an hour for math class. That hour gave me the time I wanted to have good warm-ups every day (sometimes taking up half the class with one particular problem that led to additional discussion/extension!); the hour gave me the time to go over homework the way I wanted to. And it still gave me time for a new lesson and practice.
But when I got started teaching math at the middle school, with "44"-minute periods, that was all over. (They aren't really 44 minutes - the students get no time between classes for switching, so switching time comes out of the 44.)
Making them work in 40-minute class periods
I taught elementary school for 12 years and I loved my math centers! They were great. Math class was always an hour, and we had five computers in the classroom, so having a computer center was always an option.
Then I moved to middle school. Math was 44 minutes (minus time for switching classes.....so more like 40 minutes). How could I fit more than two rotations in a 40-minute period?? I longed for block scheduling (our district has never had it)...that would make it so much easier to complete center rotations! For the first year or two of middle school, I kind of gave up on the idea of centers...the activities I wanted students to complete took longer than 20 minutes. So, that would be enough time to finish 2 rotations, IF students started the second they walked in the door and then had no time to clean up/organize at the end of class. But eventually I needed to get my centers back, so I experimented with a few different set-ups before I landed on a structure that works.
For Teacher Appreciation week, I created two FREE problem solving math wheels (they are in the same PDF file) - they can be used to teach problem solving strategies, be used as a center activity, or be used as a finished early activity. When complete, they can be added to students' binders/interactive notebooks to be used as references all year.
I hope you can use them! Just click the image to download.
Surface area is a such a fun topic to explore in the middle school math classroom! To really understand what surface area means, students need to interact with actual three-dimensional objects. Before we talk about the math formulas or how to calculate, we spend time discovering how to find surface area in our own ways.
I give students every-day items to work with. Typically, we use product boxes (rectangular prisms) with different dimensions, and I ask the students to visualize and then draw what the boxes would look like if they were taken apart and laid flat. Most students take about 5 minutes to complete their drawings, depending on how detailed they choose to be, and for the most part, they do a very good job drawing the nets of the boxes. Next, I have them spend a few minutes comparing their nets with group members, deciding whether those nets are reasonable representations of the object (even if they are drawn a little differently), and determining whether anyone appeared to be missing anything (some students will draw only five sides, and their group members are able to help them figure out what's missing).
After drawing their nets, I assign the groups two tasks - to find the surface area of their particular box and to determine a formula for the surface area of rectangular prisms. At this point, we have already studied area, so the only thing we discuss before they set upon their tasks is the actual meaning of the term surface area....we brainstorm the possible meanings and agree on the defintion. Then they set off measuring and calculating.
