"I felt guilty for not including proofs in enough detail and I decided that this year I was going to teach it well. Here is what I did:"
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
The last six weeks of geometry will focus on similarity, dilatation, indirect measurement, similarity transformation proofs, and circles: We will start with a review of real world ratio and proportion practice, interactive notes page & review, possible including activities such as New York Minute (NCTM Illuminations). We will then head into applying the properties of proportion … Continue reading Geometry: Planning the last 6 weeks
We set up our INB's for proof's today. Clearly I need to emphasize correct spelling in the future! We completed 1 proof, but it was a little rough. Tomorrow's plan is to construct lotsa proofs on chart paper. just practice, no notes...It still feels a little soul crushing though, even with hot pink paper. [update: … Continue reading Day 53: Proofblocks part 1
We did an estimation warm up, which everybody loves. Got the new learning target sheet & practiced identifying which congruence rule we were using depending on the "given's" and the picture. In some classes we also did the second page from this made by Math Teacher Mambo. I plan to introduce proof blocks tomorrow. I don't … Continue reading Day 52: Today was just OK
This was not a highly engaging lesson. I found out that all other teachers were showing movies today, & I was the only one "making them learn"
