Thick with Bricks
I always liked to start the year with a counting project to promote number sense and place value skills. For many years my classes counted the number of bricks in the building. This was also intended to help students define, organize, and sequence the steps needed to do it.
This is a picture of Maloney Magnet School at the right. A group of 4th graders counted the bricks on the front of the school this past spring (we didn’t have the time to count the entire building)…
The Parallelogram Machine
The Parallelogram Machine is meant to illustrate why rectangles are also parallelograms. I have an activity entitled Quadrilateral Sorting, or How can a square be a Rectangle? that uses 3 models of these. As you can see, the machine makes only parallelograms. How does that work?
