Lesson details
Key learning points
- When comparing two-digit numbers, the number of tens can be compared to find the greater number.
- When the tens in the numbers are the same, the greater number can be found by comparing the number of ones.
- The greater number can also be found using a number line.
- The greater number comes further in the counting sequence, so it will be further along the number line.
Common misconception
Children may think that they must see both the tens and ones in a two-digit number to compare them. They may also reverse the tens and ones and compare the ones first.
Ensure that numbers with the ones digit hidden are given to compare so that children can appreciate the relative size of the numbers. Use practical equipment and stem sentences to consolidate understanding of the structure of two-digit numbers.
