Ten-Adds: A Cool First Step to Right Brain Math Play

Ten-Adds: One Nine and Twos Eights

Ten-Adds: Ones and Nines work together to climb a mountain and Twos and Eights read together

One of the keys to Right Brain Math is exploring Ten-Adds (the numbers that add up to 10: 1-9, 2-8, 3-7, and 4-6, 5-5 and 10-0). It does help kids in addition, but it has many other benefits, and show up on Tic-Tac-Toe Squares, Number Wheels, and even Cubes of numbers. The main advantage is that kids struggle with multiplication by 6, 7, 8, and 9. Ten-Adds make Nines almost as easy as Ones, Eights almost as easy as Twos, Sevens as easy as Threes, and Eights almost as easy as Twos.

Kids can easily picture a phone number pad, which also helps them learn the basic numbers. All the ends of Tic-Tac-Toe lines going through the five in the middle are the Ten-Adds.

 Put it to use: Kids are fascinated with phones and calculators. With a phone off, have kids hit the Ten-Adds (1-9, 2-8, 3-7, and 4-6, 5-5) in both directions (1 + 9 and 9 + 1). Have them say out loud “1 + 9 = 10” etc. They are playing Tic-Tac-Toe and win every time. It can also be viewed as Sadoku or a 3X3 grid. Kids are fascinated with patterns and this can make math fun.

Next time we will explore Ten-Adds on the Number Wheel, where the connection between the numbers in each Ten-Add clearly show the similarity in patterns (example: the twos and eights create the same pattern on the number wheel) Also how they form parallel lines and relate to fives. Tune in.

More Ten-Adds: Threes and Sevens fly paper airplanes, A Five sees another Five in the mirror and Fours and Sixes work together lifting weights.
