Monday: Count by hundreds

Bruce the Bobcat has a big challenge for Bennie the Bear.

"Can we count all the way to one thousand?" Bruce asks.

Bennie smiles and opens a box of blocks.

"Counting by ones takes a long time," he says.

"Let us count by hundreds instead. Watch the flats!"

Learn it: count by hundreds

A flat is a square of 100 small cubes.

Bennie lays down flats one at a time.

He counts: 100, 200, 300.

Base-ten blocks: 3 hundreds, 0 tens and 0 ones

Three flats show 300.

Bennie keeps going: 400, 500, 600, 700, 800, 900.

One more hundred makes 1000. Ten hundreds make one thousand!
