Compare the number of objects in two sets or difference between two measures.
Lesson details
Learning outcome
I can compare the number of objects in two sets or describe the difference between two measures.
Key learning points
- We can compare two sets of items. There are more ___ than ___. There are fewer ___ than ___.
- We can use a range of vocabulary to compare two measures. Longer/shorter, taller/shorter, heavier/lighter etc.
- We can see the difference between two numbers or measures as the ‘gap’ between them.
- Cubes, bar models and number lines can help us to visualise this ‘gap’
Keywords
More - A larger quantity or amount.
Fewer - A smaller quantity or amount.
Difference - The result of subtracting one number from another. Way in which two or more things we are comparing are not the same.
Common misconception
Using less and fewer incorrectly when describing and comparing.
Reinforce 'fewer' is used for things we can count (not as many) and 'less' is used for things we cannot count (not as much). Explore a range of examples of this together.
Teacher tip
Children often describe the larger number relative to the smaller number, so it is important that they also practise describing the smaller number relative to the larger number. There are more ___ than ___ and there are fewer ___ than ___.
