We're digging deep into subtraction! In this episode Pam and Kim talk about what they mean by "memorizing" single digit subtraction facts and the relationships that can empower students to own single digit facts and apply the same relationships to more sophisticated numbers as well.
Talking Points:

The different meanings of "memorize the facts"
Relying on rote memory of facts in isolation leaves students with no other recourse
"No timed drills" does not mean no work on facts, but different work
Remove to 10
Using Doubles
Find the Difference
Remove a Friendly Number Over
Relationships are built, not rote-memorized

See episode 149 for more about the two meanings of subtraction
