This lesson teaches students how to use a number line to estimate square roots. There are examples, and assessment strategies included. The lesson uses the Math Links 8 textbook.
Reflection: this lesson needs to be taught over two days, the first day lesson will be the lesson as presented, after the lesson students will start the assignment. the next day some review examples will be done, and the assignment will be finished. The idea of having the drawn out number lines for the students to use as visuals seemed to work really well. The examples that I had were a good progression for the students to follow, but the idea of estimation completely confused them. Next time before I start using the number line to estimate square roots, i would use the number line to teach estimation, and than add in square roots.
