FAQ

Why is adding three multiples of ten a useful skill for 3rd graders?

It strengthens the understanding that tens can be counted just like single units (3 tens + 5 tens + 2 tens = 10 tens = 100), building number sense and laying groundwork for multi-digit addition.

How do these problems connect to skip-counting skills?

Adding multiples of ten is essentially skip-counting by tens across three steps, so students who are fluent with skip-counting find these problems very approachable.

What happens when three whole-ten addends sum to 100 or more?

Students must recognize that 10 tens equal 100 and correctly place a 1 in the hundreds column, which is a natural introduction to three-digit results from tens-only addition.
