Remember: Tens go with tens and ones go with ones, in any order. Say the tens, say the ones, check it makes sense.
Read and answer
Read the story, then answer.
The sticker posterMia and Ben are making a sticker poster. Ben has 43 stickers and Mia has 25. Mia puts 43 on her counting frame: four tens and three ones. She adds the tens first, and two more beads slide across the top row. Then she adds the ones, and five more beads slide across the bottom row. The frame shows six tens and eight ones. Ben tries it the other way round. He adds the ones first and the tens second. He gets the same answer as Mia. Tens first or ones first, the answer is sixty-eight.
