Ordered Pairs

We have been working with coordinate grids. A coordinate grid can help us find information, usually on a map. In my map book, there is a coordinate grid that tells me where I can find a street on a map of a particular town. Coordinate grids are labeled with numbers on the x and y axis. The first number in an ordered pair tells you how many to go over (on the grid). The second number tells you how many to go up.

I made a coordinate grid on the floor in the pod. The children had a great time playing Twister! Ms. Barry called out left hand, left foot (etc...) and an ordered pair. The children had to figure out how to get their body part to the right coordinate. You can make a coordinate grid and play at home.

Our latest discovery is that our ceiling looks just like a coordinate grid. I've accepted the challenge to label each axis (on the ceiling) so each child can find the coordinates (ordered pair) for the location of their desk. Does anyone like to hang out on ladders??????? :o)
