Today my mathematicians worked on the concept of equal and unequal when it comes to 2D shapes. I perused the internet for ways my students could practice this concept, but I was mostly disappointed and reminded of how we need to be careful how we ask students to use their time.
If I want my mathematicians to look at shapes and identify whether they've been partitioned equally or unequally, then I'd best not instead ask them to spend their time cutting and glueing. A sheet divided in half, labeled equal and unequal with shapes at the bottom that need to be cut out, sorted, and glued on the page, is going to prevent mathematicians from quality time spent practicing the actual skill I need them to learn.
Here's how I handled their practice time. Each of my mathematicians was giving one shape, like in the examples below. They met up with others, identified their neighbor's shape as equal or unequal, swapped shapes, and visited someone else. This continued until I knew they had ample time to practice. Their final task was to write "equal" or "unequal" on the back of the last shape in their possession and give it to me. Voila.
I just think we need to be wary of allowing cutting, glueing, or some other random task from preventing what's truly most important from happening.
