Three Digit Addition and Subtraction with Regrouping | Base Ten Blocks Gr 2-3

Teach 3-digit regrouping step by step with original base ten block pictures (hundreds, tens and ones). Kids learn to check the ones, then the tens: trade 10 ones for 1 ten and 10 tens for 1 hundred when adding, and break a ten or a hundred when subtracting, including regrouping across zeros. Every practice page mixes problems with and without regrouping, so kids decide instead of guessing.
