Remember: Picture the beads. Take the tens first, then the ones. If the ones row is short, break one ten into ten ones.
Read and answer
Read the story, then answer.
Pebbles at the beachMia has 64 pebbles. She gives Ben 30. Thirty is three tens, so only the tens row slides back. Six tens take away three tens leave three tens, and the ones stay still: 34. Another day Mia has 52 pebbles and Ben wants 7. The ones row has only two, so she takes the two first. Five are still to take, so she breaks one ten into ten ones and takes five. That leaves 45.
