Students will complete the yardstick challenge where they are making their own yard stick and use it to measure their heights (or other body parts - feet, armspan etc.) Through the challenge and 1 follow-up lesson, the mathematical purpose is developing understanding of linear measurement, (2.MD.A), measure in and relate different units - inches and feet (2.MD.A.2), generating measurement data (2.MD.D), relating addition and subtraction to length (2.MD.B). They will engage in mathematical practices 5 (appropriate tools) and 6 (attending to precision).
Building a maker mindset
Other mathematical purposes:
- Represent and solve problems involving addition and subtraction (2.OA.A)
- Understand place value - skip count by 5s (2.NBT.A.2)
Measuring, addition, and subtraction.
Materials Needed for this Cycle
- Blank yardstick or meterstick
- 3 inch by 5 inch index card (real index cards are better than self-made ones, which will be inaccurate due to human error)
