Puppies and Tulips (optional)
This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling. In this lesson, students make origami tulips and puppies and use problem sentence frames to tell puppy and tulip stories using “fewer” and “more”. Students solve Compare, Difference Unknown story problems with language that suggests the opposite operation. For example, problems that use a comparison statement with “more,” but require subtraction to solve. Students will work more with these problem types in grade 2.
When students make choices, adhere to constraints, and analyze real-world situations with mathematical ideas they model with mathematics (MP4).
- Action and Expression
- Analyze and solve Compare story problems with unknowns in all positions.
