Set Induction (Attention-Grabbing Story):
The teacher begins with a playful story:
“Children, yesterday I went to the market to buy oranges. The seller tied them in bunches of 5. When I got home, I wanted to count how many oranges I had, but I didn’t count one by one — I counted 5, 10, 15, 20… Can you see? I skipped some numbers and it made counting faster!”
The pupils laugh and join the teacher in clapping as they count in 5s.
Entry Behaviour:
Pupils can count numbers from 1 to 100 and identify tens and ones.
Learning Resources and Materials:
- Number charts (1–130)
- Flashcards with 2s, 3s, 5s, and 10s
- Beads, bottle covers, or sticks for counting
- Skip counting songs and videos
- Real-life objects (shoes, pencils, spoons)
Building Background Knowledge:
Teacher revises counting from 1 to 100 and reminds pupils how numbers increase by one each time. Then explains that skip counting means jumping over some numbers in a pattern.
Embedded Core Skills:
- Numeracy and logical reasoning
- Pattern recognition
- Listening and speaking
- Observation and memory retention
- Problem solving
