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.
I like to review 2-3 problems from the Perform operations with scientific notation worksheet, with the kids driving most of the thinking/doing. I particularly like the gold problems to review, since kids have to use other knowledge (e.g. converting units) to solve.
For example, with Problem_7 students are pushed to divide, and THEN do a conversion from hours to days. When kids struggle with this, I often use a question that I hope does not give away the problem, but scaffolds their understanding... I say, "I think there is a number that you need in that problem that is not explicitly stated." (That number is 24, of course. :))
Once kids get that, they tend to do well... it's just a simple step that is added to the end of the problem that actually drives the complexity up quite a bit and solidifies their understanding.
HW84 Perform operations with scientific notation is to be completed at home and should take students approximately 15 minutes.
