Guessing and Counting
Numbers can be counted in different ways. We can
count in steps of 10, such as 10, 20, 30... up to forever.
By adding one to a number, we get the next number.
For example, 299 + 1 = 300.

Using objects like matchsticks can help visualize numbers.
Arranging them in groups can make counting large numbers
easier.
VISUALIZING NUMBERS WITH
MATCHSTICKS
Using objects like matchsticks can help visualize numbers.
Arranging them in groups can make counting large numbers
easier.
For example, consider two large bundles of matchsticks.
Each large bundle contains 10 smaller bundles, and each
smaller bundle has 10 matchsticks.

For example, consider two large bundles of matchsticks.
Each large bundle contains 10 smaller bundles, and each
smaller bundle has 10 matchsticks.
To find the total matchsticks in one large bundle:
10 (small bundles) × 10 (matchsticks) = 100 matchsticks
VISUALIZING NUMBERS WITH
MATCHSTICKS
Since there are two large bundles:
100 (matchsticks per bundle) × 2 (bundles) = 200 matchsticks in
total
This method makes counting easier and helps in
understanding multiplication in a simple way.

By adding more or taking some away, the value of the number
changes. We will see how this happens.
NUMBER FUN: UP AND DOWN WE GO!
Jack brought 5 apples for everyone to share. He gave one apple
to Lily, so they had 5 apples in total. Adding 1 made the number of
apples bigger.
