Day 92: Getting Ready for Surface Area

2013-01-10_13

Next week, we begin exploring Surface Area. Part of the planning process is testing out the nets (3D shapes) that students will use to calculate the surface area of common shapes. Fun fact: a parallelogram prism is called a parallelopiped.

Day 91: What is height?

2013-01-09_12

We’re identifying bases and heights of quadrilaterals to help students calculate area. One class didn’t say much about bases (it was early in the day). To help students better think of height, I drew a stick figure on the board. That’s clearly what the art part of my degree was about.

Day 90: Geoboards

Nothing says “high school math” like manipulatives. We’re using Geoboards (like the ones above) to calculate area. More on this later. Can’t tell whether students can get more distracted by the boards or the rubber bands…

Day 89: First Day Back

2013-01-07_14

What? Vacation’s over already? Adjusted first day schedule so that students can get new schedules if they need them. We lost a few students and gained a few students.
