Addition – my own addition chart
As you learn your addition facts, ask someone to quiz you on them.
If you can say the answer right away, they will put a dot in the
answer square.
Color each square as you master the fact!

Addition – missing addend problems
Sometimes we have to solve problems when we know the answer but
we don’t know all of the problem.
Noah had 4 cars.
His grandma gave him some more so he now has 7 cars.
How many cars did she give him?
We know he had 4 cars.
We know he ends up with 7 cars.
What we don’t know is how many cars his grandma gave him.
One way to find out is to draw or use counters.
We draw 4 cars. Then we can draw more cars to get to 7 cars
altogether. We count how many more cars we drew.

4 + 3 = 7

We put 1 in the first tens frame.
We have made 10.
We need to add 4 more into the other frame.
