A word problem is a math story.
In all means you add.
Read it: Adding by counting on
You have 4 crackers. Your brother gives you 3 more. You could count them all again from 1, but you already know the first plate is 4.
Say the number you already know: 4.
Count on, 1 number for each new cracker: 5, 6, 7.
The last number you say is the total: 4 + 3 = 7.
Counting all from 1 works, but it is slow, and it gets slower as the numbers grow.
Counting on starts from a number you already trust, so there is less to count and less to lose track of.
Start from the bigger number: for 3 + 4, say 4, then count on 5, 6, 7.
To add, start at the bigger number and count on the other one.
Saying the starting number as the first count: "4, 5, 6" for 4 + 3, and answering 6.
The starting number is what you already have. The counting begins with the first new cracker: 5.
5 ducks are on a pond. 4 more come. How many ducks now? — 9. Start at 5 and count on 4: 6, 7, 8, 9. 5 + 4 = 9.
3 + 2 = 5
Mia has 3 red apples. Then she picks 2 more green apples. How many apples does she have in all?
First, let's show the 3 red apples Mia already has.
Now the 2 green apples she just picked.
Adding means joining the groups together. Let's count them all!
One, two, three, four, five. That's five apples!
Kindergarten · Joining two groups of apples
We can write this as three plus two.
Three plus two equals five.
Mia has 5 apples in all. Adding joins groups together. Great work!
