Introduction: What Does Decreasing Mean?
Let’s imagine you have ten cookies on a plate. You eat one cookie. Now you have nine cookies. You eat another cookie, and now you have eight cookies. The number of cookies is getting smaller – this is what we call decreasing!
Counting Backward
When numbers get smaller, we count backward. Let’s practice counting backward from 10:
10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
Think of it like a rocket launch countdown – we start from a bigger number and count down until blast off at zero!
Fun Activities
- The Disappearing Circles
Look at these circles. Let’s count how many are in each row:
⭕⭕⭕⭕ (4 circles)
⭕⭕⭕ (3 circles)
⭕⭕ (2 circles)
⭕ (1 circle)
Can you see how the circles are decreasing? Each row has one less circle than the row above it.
- Steps Going Down
Imagine walking down stairs. Each step takes you lower:
“`
5
4
3
2
1
“`
When we go down the stairs, the numbers get smaller!
Remember
– When numbers decrease, they get smaller
– We can count backward just like counting forward
– Each time we decrease a number, we have less than before
