Counting and comparing
I can use my knowledge of counting forwards and backwards to and from 100 and comparing numbers within 20 when solving problems.
Lesson details
Key learning points
- When we count a number of objects, we can use a range of strategies to find the total.
- We can start a count from any number and count forwards or backwards.
- We can use 'greater than', 'less than' and 'equal to' to compare numbers.
- We can represent these using the mathematical symbols > , < and =
Common misconception
Mistakes when counting in ones. Children may not be able to visualise numbers to see which is more/greater than, less than or equal to.
Children should continue to practise counting forwards and backwards from a given number to increase confidence of counting within 100. Use number lines or one hundred squares to help children visualise numbers and support comparison.
Keywords
Strategy - A plan or method to achieve a specific goal.
More than - Greater quantity or value.
Greater than - Bigger/larger in value or size.
Less than - Smaller in size referring to abstract or continuous number. E.g. less water, fewer drops.
