Number Line Jumping

 This is a fun way to add and subtract simple numbers on a number line. This idea originated from the activity that goes with Hap Palmer's "Jumping to Add and Subtract" song (see below). Create a number line on the floor by writing the numbers 0 through 9 on cards or dessert-size paper plates. Use yarn or electric tape to create the number line, and place the number cards or plates about 18 to 24 inches apart on the number line. 

To add, have the child stand on the number 2 or 3. Then add a number like 5, and have them jump or step 5 numbers ahead on the number line. 

To subtract, have them start on a higher number and jump or step backwards the number you are subtracting. 

This can also be an introduction to skip counting by twos. Have them jump to the numbers, skipping one in between.
