An easy, breezy hat that your students can make to celebrate Dr. Seuss' birthday on Read Across America Day. On March 2, your students can create a Human Number Line by wearing their hat and arranging themselves in number order. You can even practice counting, adding, subtracting, finding one more or one less, finding the number before or after, finding the number that is ten more or less, finding the even or odd numbers, counting by twos, threes, fours, or fives, counting backwards, etc. Copy the numbered circles on card stock & laminate to create a center where students put the numbers in order. Have FUN with this simple project that makes math fun!
