Counting forwards and backwards in 10s to 50
Lesson details
Learning outcome
I can recite the decade number names from 0-50, going forwards and backwards, and notice the patterns in the count.
Key learning points
- Decade numbers are used when counting forwards and backwards in tens.
- You can start counting in tens from any decade number.
- A 100 square can be used to help you count the decade numbers.
Keywords
Number names 10 to 50 - E.g. 'ten' for 10
Decade numbers - These are the multiples of ten which mark the tens boundary where the pattern of counting changes.
Common misconception
May confuse decade number names with teen numbers e.g. thirteen, thirty.
Regular identification and discussion of common errors with opportunities to correct them within this lesson can be replicated beyond it.
Teacher tip
This lesson involves oral rehearsal and interaction with key representations. As before, the slides simply act to aid lesson design and delivery. In daily routines, practise counting to 100 and beyond, including saying the number names, enumerating a quantity of objects and pointing to numerals.
