Each day, students complete a warm-up that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.
For a video narrative about how I structure each lesson, and how the warm-up fits in, click here.
For the huddle in this lesson, I like to review #4, since it has a scale factor that is not a whole number. It gets kids to move away from just their instincts (double or triple is easy) to apply the idea of image over original, which yields a scale factor of 3/2. It's also 1.5 times larger, which is a relatively simple concept for kids to master. This sets the stage for even more fractions as scale factors.
Homework is to be completed at home and should take students approximately 15 minutes.
