Maps and Grids

Maps and grids with Millie and her kitten Biscuit, from grade 4 into grade 5: rows and columns; map squares named by a letter and a number, like B3; points named by two numbers, across first and then up, like (3, 5); moving left, right, up and down; which point is higher or farther right; how far apart two points are; and the corners, sides, perimeter and area of rectangles on a grid.

Every card is a little story: “Captain Mia’s treasure is at (4, 2). How far across does she go first?” Each topic has its own world and a big seek-and-find picture to explore.
