Work on number sense with the classic game High, Low. Select a specific range of numbers to work with, such as 1-50 (featured above). For older kids, you can include negative numbers. One child is chosen to be "it." He / she chooses a number and keeps it a secret! Peers take turns guessing the numeral. The person who is it writes the number each person guessed under high or low. They write it under high, if the guess is greater than the number. They write it under low, if the number guessed is less than their number. Whoever guesses the secret numeral first wins!
