Comparing Numbers Within 10
Comparing Numbers Within 10
When we count objects, we often want to know which group is bigger or smaller. Comparing numbers helps us figure out if a group has more, fewer, or the same amount of things as another group.
What Are "More", "Fewer", and "The Same"?
- More: A group has more when it has a larger number of objects.
- Fewer: A group has fewer (or less) when it has a smaller number of objects.
- The Same: Two groups have the same amount when their numbers are exactly equal.
How to Compare Groups
One of the best ways to compare two groups is by using one-to-one matching. Imagine you have 5 apples and 3 plates. If you draw a line from one apple to one plate, you will fill all 3 plates and still have 2 apples left over! Because there are apples left over, we know that the group of 5 has more than the group of 3.
Comparing Numbers Directly
Once you know how to count from 1 to 10, you can compare numbers just by looking at them. Numbers that come later when we count are greater (more). Numbers that come earlier are smaller (fewer).
When counting: 1,2,3,4,5,6,7,8,9,10.
Since 7 comes after 3, we know that 7 is greater than 3.
Let's Practice!
Here are some examples of how to compare numbers within 10:
1. Which group has more: 5 cats or 3 dogs?
- Think about counting: 3 comes before 5. So, 5 is the bigger number.
- Answer: The 5 cats are the group with more.
2. Are there enough hats for 4 children if there are 6 hats?
- Let's match them up! If we give 1 hat to each of the 4 children, we use 4 hats. We started with 6 hats. Because 6 is greater than 4, we have extra hats left over.
- Answer: Yes, there are enough hats!
3. Which is the greater number: 3 or 7?
- Remember our counting order. 7 comes after 3.
- Answer: 7 is the greater number.
