Estimation Strategies!

Estimation means making a smart guess that is close to the real answer. It's super useful when we need a quick answer!

Estimation is a smart guess that is close to the exact number.

We don't count every single thing — we round and guess!

It's like saying "about 30" instead of counting exactly 28.

Round each number first, then add!

67 - 29 → about 70 - 30 = 40

Real answer is 38 — close enough!
