Name_____________________________________________
I can solve addition word problems within 20.
Draw a picture to solve each problem. Write the addition problem in the box.
1.OA.1
1. Alexis had 4 f ish. Brianna had 2 f ish. How many f ish did the girls have altogether?
2. Shane checked out 2 books. Tad checked out 3 books. How many books did they check out in all?
3. Miguel had 3 crayons. Ross had 4 crayons. How many crayons did they have altogether?
4. Jeff saw 1 rabbit. Soon, 4 more rabbits came. How many rabbits were there altogether?
The nest had 3 eggs.The mother bird laid 1 more egg.How many eggs were there in all?
Sometimes, it helps to draw a picture about a word problem.So, 3 eggs plus 1 egg equals 4 eggs in all.
