Today’s activities are all about addition, counting and place value. They are designed to engage our young children in deep mathematical thinking as they explore possible solutions.

A TRIP TO THE AQUARIUM
Gina went to the aquarium yesterday.
She learned that some sea animals have arms.
![]()
One of the tanks had sea stars and squid in it.
Gina counted 50 arms in the tank. Wow, that’s a lot of arms!
Show or tell what you know about the arms in the tank. Use pictures, numbers, symbols, or math words.
How can you get started?
-
Think about how many sea stars and squid it takes to make 50 arms in all.
Remember, each sea star has 5 arms and each squid has 10 arms.
There’s more than one right answer! -
You might start at 0 and count by 10s and 5s to get to 50.
Count 10 for each squid in the tank. Count 5 for each sea star. -
If it helps, draw simple pictures to help you keep track of the total number of arms.
