This is a simple way to encourage math (or other curriculum areas) in the Block Center. Create a parking lot using a vinyl placemat. Use a ruler to make 8-10 parking spaces. Tape a different color of circle in each space. When the children are done playing with the cars at the Block Center, have them park them in the appropriate spot. If colors are too easy for your kids, write capital letters on the hoods of the cars and the corresponding lower case letters. Or try numerals and dots. Have other ideas?
