Cognitively Guided Instruction, Lesson 10:
Rate and Price: Multiplication, Measurement Division, Partitive Division.
Ways to learn:
- Lecture :
- video 1 (introduction to word problem types);
- video 2 (direct modeling multiplication and measurement division with Cuisenaire rods)*
- video 3 (direct modeling partitive division with Cuisenaire rods)*
- video 4 (recap: comparing these to grouping problems, direct modeling strategies the use Cuisenaire rods)
- text
- Read Children's Mathematics Chapter 4: Multiplication and Divisionpgs 46-47..
*oops--I realized that I used two white 1-rods rather than a red 2-rod when I was showing 12. Not perfect. Sorry.
