Ordering numbers 11- 20 practically
Lesson details
Learning outcome
You can compare and order numbers 11-20 practically.
Key learning points
- Understand numbers to 20 in the ordinal context, as part of a number track or line.
- Use the language of first second and third to order numbers and sets of objects to 20.
Keywords
First - The smallest of the values.
Second - The middle value of a set of three.
Third - The largest of the values.
Common misconception
You can't compare and order numbers that are not next to each other in the counting sequence.
Start with numbers close together in the counting sequence and move on to numbers with a larger gap.
Teacher tip
Start by comparing numbers of object in a set and move on to the language that allows us to say that 15 is greater than 12 even if we are not labelling a set. We are saying that 15 ones is greater than 12 ones.
