Remember: Start at the top row and say the hundreds, then the tens, then the ones. An empty row still counts as zero.
Read and answer
Read the story, then answer.
The hat orderMia and Ben make hats for the school party. Their teacher puts an order on a counting frame: two beads on the hundreds row, none on the tens row and seven on the ones row. Ben is in a hurry. He reads two, seven, and skips the empty row. Mia writes twenty-seven on the order slip and they make twenty-seven hats. That is far too few! Then they read the frame again, top row first, and get it right.

Reading the order
1The top row We start at the top row, the hundreds, and read down.
2207 Two hundreds, an empty tens row and seven ones: 207. The zero holds the tens place.
3True Skip a zero and the number gets much smaller.
4305 Three hundreds, no tens and five ones: 305.
5C Seven hundreds, four tens and an empty ones row: 740.
6608 Six hundreds, an empty tens row and eight ones.
71-C, 2-B, 3-A Say each row's count with its name, hundreds first.
83, 1, 2 We read from the top row down.
9No A frame is read by its rows, not by counting every bead as one. It shows 207.
10702 Seven on top and two below would be seven hundred two, a different number.
11305, 604 305 and 604 have a zero in the tens place. 350 has an empty ones row.
12No He skipped the zero tens. The number is three hundred six, 306.
