Work it out!

Give it a try! Yesterday, Alex saw 14 birds in his backyard. Today, he saw 12. How many birds did he see in all? Write a number sentence and SOLVE it.

If you wrote… 14 + 12 = 26 then… You’re right!

Step 4 LOOK BACK. Does your answer fit the question?

We had to find out how many birds Alex saw in all. We added the number he saw yesterday and the number he saw today.
