How do you label fractions on an open number line? How do you label a fraction of a candy bar? How many cuts do you make to cut a candy bar into fourths? Pam and Kim invite you to revisit episode 138, this time with an ear towards fractions.
Do your students ever get confused about counting obects vs counting distance? In this episode 138 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"!
