  1. The First Step The first step in learning number sense should be to memorize the PERFECT SQUARES from 12 = 1 to 402 = 1600 and the PERFECT CUBES from 13 = 1 to 253 = 15625. These squares and cubes should be learned in both directions. ie. 172 = 289 and the 289 is 17.

  2. Perhaps making yourself flash cards will help the process of memorization.

  3. Perfect squares & cubes DrillDepending on how much you would like to practice, number your notebook paper 1 thru 134. For the next slides you will have 6 seconds per slide. Try doing the questions mentally.

  4. At any point you want to stop, go to the very end of this presentation to check your answers.Award yourself 5 points for every correct answer. Deduct 4 points for every wrong answer, scratched out answer, skipped problem, and problem you had scratch work.

  5. Perfect squares & cubes DrillThe highest possible score will be 500, the lowest -400.The more you practice the better you will get! Have FUN!!
