Math in Our World: Trains, Trains, Trains

5 train track pieces. 3 are straight and 2 have curves. 4 rows of train cars. One row has 6 gray train cars. Then a row of 2 brown train cars. Next a row of 5 red train cars. And a row of 3 green train cars.

Hayden and Charlotte decided to play with trains today.

They wanted to make sure to share the trains fairly. They lined them up to see how many they had.
