Teaching about Angles―A Hands-On Approach

What am I doing on the floor? Teaching angles to fourth graders. Read about how instruction using Pattern Blocks and hinged mirrors, along with supporting number talks, can help students learn to understand and measure angles. Here I present a (sort of) photo essay to describe what actually occurred over the first three days of instruction. Ideas for continuing the instruction follow.

When You Multiply by 10, Just Add a Zero? Horrors!?!

Have you ever asked students to solve 12.6 x 10, and they respond that the answer is 12.60? I have, many times. Students who do this apply a pattern that works when they multiply whole numbers by 10—they tack on a zero to the end of the number they’re multiplying. But then they apply the same pattern when working with decimals. What can we do?

Read how 7th graders collected and analyzed data about the frequency of letters. They chose sentences, recorded the frequency of letters, and put their data on a class chart. Then we compared the class results to the actual frequencies of letters. Engaging the students in collecting their own data gave them an authentic math experience, not rigged by me in any way.
