Getting ready for long division:

Adding and subtracting accurately:

  1. Math Lines- Subtraction– start with subtracting to 1, then to 2, etc.
  2. Math Lines Menu– shoot a marble

 Practice with divisibility rules (factors)- a page on my site

Division models:

  1. Model a basic division problem as an area model

Division Algorithm, step-by-step

  1. Division game– Frog Math- click PLAY
  2. Long Division– harder to see at first, but give it a shot.
  3.  Soft School’s Long Division
