FAQ
What strategy works best for adding three multiples of 10?⌄
Students can add the first two multiples of 10 and then add the third, or look for pairs that combine to a whole hundred (e.g., 30 + 70 = 100) before adding the remaining multiple.
How does three-addend whole-tens addition connect to mental arithmetic?⌄
Fluency with three-addend tens problems builds the mental chunking ability students need for quick estimation and mental addition of larger numbers.
What prerequisite skills should students have before tackling three-addend whole-tens problems?⌄
Students should be fluent with two-addend whole-tens addition and comfortable adding three single-digit numbers before combining both skills in a whole-tens context.
