Other Examples:

  • Counting on: "How much is 4 and 3 more?" "Fourrrrr...five, six, seven [uses rhythmic or finger pattern to keep track]. Seven!"
  • Counting-up-to: May solve missing addend (3 + _ = 7) or compare problems by counting up; e.g., counts "4, 5, 6, 7" while putting up fingers, and then counts or recognizes the 4 fingers raised.
  • Asked, “You have 6 balls. How many more would you need to have 8?”, says, “Six, seven [puts up first finger], eight [puts up second finger]. Two!”

Help your student become a(n) Counting Strategies +/-

These activities challenge children to solve all the addition and subtraction problem types they have already learned to solve by counting on with objects with more sophisticated counting strategies, including counting on or counting up (or down) from one number to another.
