The preschoolers practiced one-to-one correspondence today while playing with megablocks. When you are counting with your preschooler make sure to only say a number aloud when your finger touches the object, or in this case, the black dot. We always count from left to right. After we counted dots it was time to find the right number and build a match. This is a super easy and fun way to practice math skills. Try with some blocks at home!
