Write the adjacent multiple below the given number on the left and the adjacent multiple above it on the right. Circle the nearer value. At halfway, circle the greater value.

Learning objective
What this activity builds
Explain rounding as a comparison between two adjacent multiples, rather than a memorized digit change.
Worked example
Round 743 to the nearest ten by comparing its neighbors.
740 < 743 < 750; circle 740.
743 is 3 away from 740 and 7 away from 750. Both neighbors are needed: 700 and 800 are hundreds, so they do not answer a nearest-ten question.
Teaching notes
Make the practice count
- The example option completes the first position in each of the two groups. Stars identify these unscored examples.
- Each remaining position has three marks: one for each neighboring multiple and one for circling the correct value. A default sheet has 18 scored positions and 54 marks.
- These questions avoid exact multiples so that the lower and upper candidates are different and strictly surround the input.
- Turn off examples for independent assessment. The generated numbers remain the same, letting you compare practice and assessment fairly.
