Adding Within 10
Put them together. Count them all!
Hi! It is me, Dot. Let's add!
Adding means putting groups together.
Count all the bugs to find how many in all.
The + sign means add. The = sign means equals, or is the same as.
Picture Adding
Each card has red bugs and blue bugs. Tap every bug to count them all.
The last number you say tells how many in all!
-
1 + 2 = 3
1 bug and 2 bugs make 3 bugs.
Tap every bug to count them all!
-
2 + 3 = 5
2 bugs and 3 bugs make 5 bugs.
Tap every bug to count them all!
-
4 + 1 = 5
4 bugs and 1 bug make 5 bugs.
Tap every bug to count them all!
-
3 + 4 = 7
3 bugs and 4 bugs make 7 bugs.
Tap every bug to count them all!
-
5 + 3 = 8
5 bugs and 3 bugs make 8 bugs.
Tap every bug to count them all!
-
6 + 4 = 10
6 bugs and 4 bugs make 10 bugs.
Tap every bug to count them all!
Hop on the Number Line
Dot starts on the first number. Tap Hop to jump forward one space for each number you add. Where does Dot land?
3 + 4 = ?
Dot is on 3. Hops: 0 of 4.
Tap & Hear
Tap the yellow card to hear the adding problem. Then tap the big number that shows how many in all. There are 5 rounds. Use Tab and Enter to play with a keyboard.
For Grown-ups
This page practices early adding from the Common Core math standards for kindergarten and grade 1. Every sum on the page is 10 or less.
- Show adding with objects, drawings and equations (K.OA.A.1).
- Add within 10 by using objects or drawings (K.OA.A.2).
- Add fluently within 5 (many sums on this page are 5 or less) (K.OA.A.5).
- Relate counting to adding, like counting on by hopping on a number line (1.OA.C.5).
- Add within 20, with fluency within 10, using strategies such as counting on (1.OA.C.6).
Try it: put out a few spoons, then add a few more. Ask, "How many in all?" Let your child touch and count each one.
Counting on: on the number line, your child starts at the first number and counts forward. This is a big step past counting from 1.
