Monday: Add tens, then ones

Riley the Raccoon holds his lantern over a pile of puzzle pieces.

"I have 34 pieces, and Bennie has 25," says Riley.

"How many pieces do we have together?"

Bennie the Bear sorts the pieces into bags of ten.

"Let us add the tens first," he says.

"Then we add the ones."

Learn it: tens with tens, ones with ones

Riley has 3 tens and 4 ones. That is 34.

Base-ten blocks: 3 tens and 4 ones

Bennie has 2 tens and 5 ones. That is 25.

Base-ten blocks: 2 tens and 5 ones

Add the tens: 30 + 20 = 50.

Add the ones: 4 + 5 = 9.

Put them together: 50 + 9 = 59.

Base-ten blocks: 5 tens and 9 ones
