FAQ

Why use whole-tens values for missing minuend practice?

The round numbers simplify the arithmetic, letting students focus on the inverse-operation concept — finding a missing minuend by adding — without the distraction of complex regrouping.

What does a typical whole-tens missing minuend problem look like?

Problems take the form ? − 40 = 30, where students add 40 + 30 = 70 to find the minuend — straightforward computation that reinforces the inverse-operation strategy.

How do these problems connect to fact families?

They reinforce fact family thinking — if 70 − 40 = 30, then 40 + 30 = 70 — showing students that addition and subtraction facts are interrelated pairs.
