Join numbers together! The more the merrier!
Take some away and see what's left!
Fast adding! Groups of groups!
Share fairly like a pizza party!
Addition is like inviting more friends to the party! The more you add, the bigger the fun gets. Ready?
Addition means putting numbers together to make a bigger number. We use the plus sign + and the answer is called the sum.
3 apples + 2 apples = 5 apples!
2 + 3 = 5
4 + 1 = 5
6 + 2 = 8
5 + 5 = 10 (that's a pair of hands!)
When numbers get bigger, we sometimes need to "carry" a ten to the next column. It's like packing extra socks into the next suitcase!
27
+ 15
โโโโ
42
7 + 5 = 12 โ write 2, carry the 1
2 + 1 + 1 (carry) = 4
Emma has 18 stickers. Her friend gives her 25 more. How many stickers does she have now?

789 + 456 = 1,245
3,478 + 2,659 = 6,137
Subtraction is taking away โ like eating cookies from a jar and counting what's left. Let's go on a Minus Mission!
Subtraction means taking some away. We use the minus sign โ and the answer is the difference.
5 cookies โ 2 cookies = 3 cookies left!
8 โ 3 = 5
9 โ 4 = 5
7 โ 7 = 0 (all gone!)
10 โ 1 = 9
Sometimes the top number is smaller. We "borrow" from the next column โ like asking a friend for a ten!
42
โ 17
โโโโ
25
2 is smaller than 7, so borrow 1 ten โ 12 โ 7 = 5
Then 3 (left after borrowing) โ 1 = 2
There were 53 birds on a tree. 28 flew away. How many are still there?
1,000 โ 467 = 533
8,503 โ 2,786 = 5,717
Multiplication is super-fast addition! Instead of adding the same number over and over, we multiply. It's like having many groups of the same thing.
Multiplication means repeated addition. We use the times sign ร (or *). The answer is the product.
4 groups of 3 stars = 3 + 3 + 3 + 3 = 12
So 4 ร 3 = 12
2 ร 1 = 2 2 ร 2 = 4 2 ร 3 = 6 2 ร 4 = 8 2 ร 5 = 10
5 ร 1 = 5 5 ร 2 = 10 5 ร 3 = 15 5 ร 4 = 20 5 ร 5 = 25
10 ร anything is easy: just add a zero! 10 ร 7 = 70
Learn the times tables up to 12. Then try two-digit ร one-digit.
23 ร 4
20 ร 4 = 80
3 ร 4 = 12
80 + 12 = 92
There are 6 boxes. Each box has 8 crayons. How many crayons altogether?
24 ร 15 = 360
47 ร 36 = 1,692
Division is sharing equally โ like cutting a pizza so everyone gets the same amount. Fair and fun!
Division means splitting into equal groups. We use the divide sign รท. The answer is the quotient.
6 pizza slices shared by 2 friends = 3 each
6 รท 2 = 3
10 รท 2 = 5
12 รท 3 = 4
15 รท 5 = 3
8 รท 1 = 8 (sharing with just yourself!)
Sometimes things don't divide evenly. What's left over is the remainder.
17 รท 5 = 3 remainder 2
(because 5 ร 3 = 15, and 17 โ 15 = 2 left)
24 candies shared equally among 6 kids. How many does each get?
144 รท 12 = 12
1,568 รท 28 = 56
