Dot Paper


Dot paper is a great way to create area problems for students to solve. The best part about it is that it forces students to figure out which measurements are important, instead of just giving them a diagram already labeled.

A word of caution: some students will just count the dots instead of counting the spaces between the dots. It's a good idea to do at least one sample problem first.

Writing in Math

I tried a new writing activity in class. (I have to admit, it was mainly because I knew the lesson was a little short and I would need to fill an extra 5 or 10 minutes) Anyway, I was actually pretty impressed with how it worked out. I'm starting a chapter on area and volume. The book immediately jumps to the area of parallelograms and trapezoids. Maybe your kids are different, but I knew mine would barely remember how to find the area of a rectangle or triangle so I thought we better spend a day reviewing those. Before we took notes, I had the kids fold a paper in half: hot-dog wise in case you're wondering :-) On the left side they had to answer 4 questions about area and perimeter - just so I could see what they remembered from last year. I gave them a couple minutes to write down what they knew and then had them set it aside. At the end of class, after taking notes and working on problems with a partner, I had them take the sheet back out and write down whether their original answers were correct. If not, they had to write down the correct answer. I just walked around the room collecting them - it was a super short and easy way to see which students understood the lesson and which ones still needed help. I think I might try it again . . .

Connect Four

Today we played Connect Four as a review game on the SmartBoard.



It didn't go as well as I had planned. I thought it would be fun, but they spent more time arguing over where to go and accusing me of favoring one team over the other. Maybe next time I just shouldn't play it on a Friday.
