Do you ever fall into the "off by one" trap? Do your students ever get confused about counting objects vs counting distance? In this episode Pam and Kim use a Problem String to help build intuition about everyday subtraction problems.
Talking Points:
- Experience a Problem String to build relationships
- Fencepost Problems are all over the place
- Students can't just pluck numbers out of Fencepost problems
- Cathy Fosnot's replacement unit, "Measuring For the Art Show"
- Other places these kind of problems show up
- Kim explains her strategy
See episode 111 for more about "Measuring For the Art Show"!
