FAQ
Why add three multiples of 100 instead of just two?⌄
Three-addend problems require students to hold an intermediate sum in working memory and add a third value — developing mental math stamina beyond simple two-number addition.
What strategy works well for three whole-hundreds addends?⌄
Add the first two hundreds together, then add the third — or look for a pair that makes an easy benchmark (like 400 + 600 = 1,000) before adding the remaining number.
How do these problems prepare students for larger multi-addend tasks?⌄
The pattern learned here — add the significant digits, keep the zeros — scales directly to adding whole thousands, ten-thousands, and beyond.
