Math Halloween Games

Here are a few more Halloween games, focused on math. These would probably work best for older kids (2nd grade and up).

PUMPKIN WEIGHT – Purchase a 6-7 pound pumpkin, weigh it on your bathroom scale, and record the weight. Ask the children to pick up the pumpkin, guess the weight, and write down their estimates. The child who comes the closest to guessing the actual weight can take home the pumpkin or a mini pumpkin as a prize. (You may want to have a few favors on hand in case more than one child makes a close guess.)
PUMPKIN CIRCUMFERENCE - Modify the above guessing game by having the children guess the circumference of the pumpkin using pieces of string. (You'll need a ball of string and scissors to do this.) One at a time, ask each child to cut a length of string that they believe is the distance around the pumpkin. After everyone has cut a piece of string from the ball, wrap a length of string around the pumpkin and cut it to get the exact circumference. Ask each child to measure his or her string against the string representing the actual circumference, and determine the winner(s).
HALLOWEEN GUESSING JAR - Fill small jar(s) (mayo jar, baby food jar, etc.) with candy corn, plastic spider rings, or other Halloween items. Ask the children to write down the number of pieces they believe to be in the jar. As a group, count the pieces of candy corn in the jar. The child who's guess is closest to the actual number gets to take home the jar of candy.
