Kakooma Competition


This week’s tip takes advantage of one of my Game Leaderboard Templates to run a competition where students practice hundreds of mental math facts (and have fun at the same time!) by playing the online game, Kakooma.

Important Note:
The teacher will need a Google account to use the leaderboard template. Students will NOT need Google accounts. No accounts are needed to play Kakooma.

How it Works:
The teacher will use a template to open a pre-formatted leaderboard spreadsheet. Students will use the provided form to submit their Kakooma times. The spreadsheet will collect the student student data and will show the all-time leaders, the leaders for the week, and the leaders for the day.

Teacher Instructions:

 Getting Ready

  1. Go to: http://gregtangmath.com/Kakooma
  2. Choose the Kakooma game (Addition, Negatives,
    Times, or Fractions) you want students to play:
  3. Determine the level (Easy or Hard) and number
    (4, 5, 6, 7, 9) you want students to play
  4. Decide whether you want students to play individually or
    in teams.


Using the Leaderboard Template

  1. Make sure you are logged in to your Google account.
  2. Click here to make a copy of the template.
  3. Follow the on-screen instructions to set up and use the leaderboard and to view the results.



Student Instructions:

  1. Go to http://gregtangmath.com/Kakooma
  2. Choose the game and level as directed by your teacher.
  3. Open the form. (A URL or QR code will be provided by your teacher.)
  4. Enter your name and time.
  5. Click “Submit.”
  6. Repeat steps 1-5 each time you play Kakooma.


  • School competition: Set up a whole-school competition where each class submits its top scores.
  • Teacher competition: Get teachers excited about math by setting up a teacher-only Kakooma competition.
  • Level the playing field: Assign Kakooma levels to individual students based on their abilities. Struggling students might play 5 number Kakooma while advanced students might play 7 number Kakooma. Or stuggling students can play the easy version whereas other students play the hard version of the same game.
  • Team Competition: Group students into teams of 2 or 3. Students in each team work together to solve the Kakooma puzzles as quickly as possible and then enter their team name and times into the form.
  • Offer prizes or extra credit points for game leaders.
