Learning Ninja Facts

  • Since the Birches students are learning their doubles Facts, they can extend those facts into harder doubles facts!

    Grades 1 and 2

    After learning all of double facts from 0 + 0 through 12 + 12, now try these:

    13 + 13 = 26

    14 + 14 = 28

    15 + 15 = 30

     

    20 + 20 = 40

    25 + 25 = 50

    50 + 50 = 100

     

    Grades 3, 4, and 5

    After learning all of the double facts from 0 * 0 through 12 * 12, now try these:

    13 * 13 = 169

    14 * 14 = 196

    15 * 15 = 225

     

    20 * 20 = 400 

    25 * 25 = 625

    50 * 50 = 2,500

     

    Good luck to everyone!!!!!!
