Geometry: Parallel Lines, Transversals, and Special Angle Pairs

It has taken me about three years to grasp the point of this unit. The angle relationships are later used in Unit 6 Quadrilaterals and Unit 7 Properties of Two Dimensional Figures.

I have noticed in the past that students sometimes struggle with all the numbers assigned to the angles. A fellow teacher at a math and science symposium shared this star-dot labeling she has used in the past. She said that this is to be used once an exploratory is complete where a student builds an understanding of congruent and supplementary angles. This allows the students to quickly relate two symbols with location instead of dealing with the numbers.

What happened??!?!?

"What happened?" is the question that just seems to resonate in my brain. My Algebra 1 kids bombed their test. I had such high expectations. All I want to do is cry....

A few tears later...

Alright, I will figure this out and we will come back stronger and better.

Game plan:

1. I gridded student responses (right/wrong) against names.
2. We have tutorials 7:30 am to 8 am and 3:35 pm to 4 pm. Starting tomorrow afternoon, I will have students that missed certain questions attend tutorials on a certain day. Example: All students that missed number one will attend morning tutorials Thursday. A revised question will be a half credit towards the original test grade.
3. I plan on the students completing an in depth revision for each question by identifying properties, writing explanations, and justifying their solution. I use the Cornell notes systems as a guide for organizing the process.
4. During class I will give what I call quiz strips. These consist of two to three problems. I create two to three sets of differing questions. Purpose: Students cannot cheat, but they can collaborate and teach each other about the concept.
5. I will administer accumulative quizzes. These quizzes focus on several concepts at once with a few questions.
6. We will retest. This method of repetitive practice and accumulation has proven true with my juniors in Algebra 2. There's not a function that they cannot transform or a transformation they cannot read. They love transformations of functions.
7. OVERALL: I am focusing on my level of questioning. I have several versions of Bloom's Taxonomy printed and posted around my classroom to help prompt and remind me of the higher level of vocabulary to use.

Looking for...

I am looking for strategies in Algebra 1 to build fluency in the foundational skills. Game ideas, practice methods, anything???
