Cross-Out: Sums to 12

Chris asked for a new game yesterday, and I didn’t have one ready (Gasp!) So we made one up together called “cross-out”. This was quick, easy to organize, and he had fun playing it and ‘cheating’.

Materials: white board, dry-erase marker, two dice (we used dot dice, but you can use number cubes to up the level of thinking)

Objective: We played as a team. The goal is to cross-out every sum when rolling two dice (2-12).

How to Play

  1. Have your child write the numbers 2-12 on the white board. This is great fine-motor practice! cross out 9
  2. Player 1 rolls the dice and adds up the values. Player 2 crosses out the sum on the board. I rolled a 9, so Chris had to find the 9 and cross it out (see below).cross out 9
  3. Player 2 rolls the dice and adds up the values. Player 1 crosses out the sum on the board. If a sum is already crossed out, continue rolling (and therefore practicing addition and counting on) until you get a sum that you can cross out. No losing turns here!
  4. Once your team has crossed-out every sum, you won! Do a silly dance to celebrate your success!

Fun Note:
When we only had the 3 to cross-out, Chris asked if we could change dice to be 0-5 instead of 1-6. “Why?” I asked. “So that I have a better chance of rolling a 3! The only way I can get it is with a 1 and a 2 and that’s tough!” If I had the 0-5 dice at my fingertips, I would have totally given in. This is a great statistics insight for such a tiny human!

He rolled a few more times, got sick of rolling and decided to just roll one die. BAM! First roll he got a 3. He was very proud of his ‘cheating’ scheme!3

Differentiation Ideas:

  • Use a number cube and a dot die to work on counting on (Level 2).
  • Use two number cubes to work on addition rather than one-to-one counting with dots.
  • Use cubes that have larger values and work on the teens/twenties. I buy square wooden cubes at a hobby/craft shop and use a Sharpie to make whatever dice I want to use. Easy and cheap!
  • Play against each other. Each person could write 2-12 and see who can cross-out their board first.
