Page 2 - HA- Counting on and sequence
P. 2
A sequence is a list of numbers that follow a pattern or rule.
What is a Backward Sequence?
A backward sequence is a pattern where the numbers go down.
How to Spot the Pattern?
• Look at the difference between numbers
• See what number is being subtracted
Example Sequences:
Back by 2s: 20, 18, 16, 14, 12, __
Back by 5s: 50, 45, 40, 35, 30, __
Back by 10s: 100, 90, 80, 70, __
Learning Outcomes
Students will be able to:
1. Accurately count backwards from a given number using different step sizes (1s, 2s,
5s, 10s).
2. Fill in the missing numbers in backward counting sequences.
3. Explain the rule of a backward number pattern.
4. Apply counting back in solving basic subtraction problems.
5. Demonstrate understanding through oral, written, or practical activities (e.g.,
number lines, games, worksheets).
