We can use math to understand
the things around us.

We can estimate the number of:
apples on a tree
birds in the sky
wheels on a train
jellybeans in a jar

If you counted 5 apples in one
area of the tree,
You could estimate the number of apples in the whole tree.

If you counted 2 birds
on the fence,
You could estimate the number of birds in the sky.

If you counted 4 wheels
on one car,
You could estimate the number of wheels on the whole train.

If you counted the number of jellybeans in one section,
You could estimate the number of jellybeans in the whole jar.
