I assigned this as a final project for my geometry classes. I wanted to see (and I wanted students to see) how well they could apply their mathematical skills to real world applications. I struggle with being less helpful, while keeping students from giving up, so i really studied all of the suggested questions that … Continue reading Days 157, 158, 159, 160: Rolling Cups

# 180 Days of Geometry 13-14

A snapshot of every day in Geometry

# Day 155 & 156: The Triplets of Cellville

I chose this Mathalicious lesson because we have not used circles enough in my geometry classes. We stared the school year with constructions, but haven't used them much this semester and I wanted them to recall and extend prior learning. I also wanted students to gain more experience modeling real world scenario's with mathematics & … Continue reading Day 155 & 156: The Triplets of Cellville

# Day 151 & 152: Similarity transformation proofs

I waited until the end of the school year for this because I wanted to encourage retention by requiring students to remember basic transformations in addition to applying dilatation which we just worked on. I searched for a good way to help students develop understanding of this. The best description of this standard that I … Continue reading Day 151 & 152: Similarity transformation proofs

# Day 151: Scale factor Area Volume Quiz

Last day for Seniors!! We assessed the learning target on scale factors impact on area and volume. Many students will have to re take this one. As I mentioned earlier, I need to do more with developing this concept next school year.

# Day 150: Getting organized

Since Friday is the last day for seniors, I decided to differentiate today. Students worked on a variety of things. I assigned specific work to some and I allowed others to chose: 1) finish Scantron bemchmark assessment 2) work on 4 four's 3) practice with similarity and its effect on Area & Volume 4) re … Continue reading Day 150: Getting organized

# Day 148 & 149: Four fours

I'm surprised how much students struggle with four fours. I think I should do this earlier in the school year next year so that they can practice many the standards of math practice in an environment where they are more familiar with the basic math skills required. Additionally, I should add a part 2 where … Continue reading Day 148 & 149: Four fours

# Day 147: Practice similarity with Area & Volume

I had a sub. Students used their interactive notes to practice applying similarity to area and volume. I'm not sure why, but students really struggle with this concept. I need to find a better way for them to SEE the impact of a scale factor on area & volume next year. This was the highlight. … Continue reading Day 147: Practice similarity with Area & Volume
