Math in Our World: Snakes & Ladders

Sasha's driveway has 45 squares for the Snakes and Ladders game. There are 9 rows and each row has 5 spaces. Each space is labeled with the a number, counting by 1s from 1 to 45. The numbering starts in the bottom left and goes to the top right. Four snakes and five ladders connect spaces across the board.
Sasha's Driveway
Rayne's driveway plan is a sketch on grid paper, 8 feet wide by 18 feet long. The bottom row is drawn to show 4 equal spaces. It looks like there are 9 rows.
Rayne's Driveway Plan

Sasha drew this Snakes and Ladders game in his driveway. Rayne wants to make one, too. First Rayne measured their driveway. Then Rayne drew a sketch of their driveway to find out how many squares of the game board they could fit.
