Big idea: Children need to link three things: the number word ("five"), the numeral (5), and the quantity (5 objects). They also learn that numbers have different jobs: telling how many, naming which one (a house number, a day on the calendar), and measuring (age, time, temperature).
Common difficulties:
- Mixing up 6 and 9, or 2 and 5. Point out how they are different, and practise with real objects.
- Writing numerals backwards. Normal at this age. Make writing fun and large: in the air, in sand, with chalk. Don't worry about neat printing yet.
- Saying 12 as "one-two". Connect teen numbers to "10 and some more" with ten frames or egg cartons.
How to help: Go on number hunts. Read the calendar each morning. Let your child press the numbers on the microwave. Read counting books together. Talk about 9-1-1 and when to use it.
Next: the lesson Numbers 11 to 20 builds on this, so your child can read and write all the numbers to 20.
