Activity
Valencia is playing in the sand at the beach, when she
notices something amazing. If she writes any addition
problem in the sand, the answer washes up on the shore!
Let’s watch the answers come in on the tide, and see if you
can keep up with the sea!
Valencia writes 14 + 4 in the sand. Can you figure out the
answer?
Did you get 18? 14 + 4 = 18!
Now Valencia writes 11 + 8. What will the sea say?
Here comes the answer: 11 + 8 = 19! Did you get the same
answer?
Valencia wants to know what 13 + 2 equals. What do you think
the answer is?
Watch out for the next wave! The answer is 15. Awesome
work!
Valencia writes 10 + 7 in the sand. What do you think the
sea will say?
10 + 7 = 17. The waves got it right, did you?
The last addition problem Valencia writes is 13 + 4. Can you
add these two numbers together?
13 + 4 = 17! That’s right.
The sea is proud of your work, and says, “Good job!”
Question
What is 12 + 3?
Using a number line, start on the 12, then jump three times to the right. You land on 15. The sum is 15!
