Remember: A carry is ten in a full row trading for one bead on the next row up. Count the new bead too.
Read and answer
Read the story, then answer.
The bead stallMia has 36 beads and Ben has 28 beads. They add them on the counting frame. Mia puts 36 on it: three tens and six ones. Ben slides 8 more ones across. The ones row only holds ten, so four beads have nowhere to go. Here is the clever part: a full ones row trades for one ten. Ten ones slide back and one bead slides up on the tens row. Four ones stay behind. Now count the tens: three tens, two tens and the new ten. That is six tens and four ones.
