CLASS FAVORITE! This digital game supports students from skip counting, to multiplying, to dividing, and remainders with multiple levels and endless fun. This is the game our students beg to play. Multiple ways to plays allows for a short warm up to a full class activity that has students thinking, laughing, and learning.

Step 1: Create Teams (or individual groups)

There are many ways to play. Students may play individually or in small groups of 2, 3, or 4. We often play as a warm up as students against teacher, or split the class up into 4 groups as teams.

Step 2: Decide on the Rules

One thing we love about Rainbow Multiples is there are nearly endless ways to play! Depending on time, decide on the rules you will use. Some common games are,

  • Connect Four (First player or team to earn 4 in a row wins. You may decide if diagonals are or are not allowed.)

  • Sequence (First player or team to earn 5 in a row wins.)

  • Bridge (Players or teams attempt to make a "bridge" across the board from top to bottom. This can be a good method of play for younger or struggling students as they tend to stick to the top of the board or smaller multiples, Bridge requires them to work on the larger values as well.)

  • Blackout (The longest and most difficult. It can be very hard to fully Blackout the board.)

  • Coloring (In this method players are not looking to "win" but to cooperate to make a fun picture. Each player switches colors, so selecting 4 players even if working individually or in smaller groups is ideal.)

Step 3: Play!

Select SKIP to jump into the game. Use the drop-downs to select the number of players or teams and the level (begin with Level 1).

Player (or team) 1 selects "Roll" to roll the dice. The game will show the roll and give instructions based on the value. A roll of 1 allows players to select any odd number while a roll of 2 allows players to select any even number. If students are not yet familiar with even and odd, teachers may assist and explain even numbers are the multiples of 2 or numbers we say when counting by 2's and odds are all the rest. Rolls from 3-10 allow players to select any multiple of the number. For instance, if rolling a 5 students should lean on the previous exercises (counting by 5's, Hide and Seek, etc.) to think about what numbers are multiples of 5. Rolling an 11 requires students to select any prime number and rolling a 12 requires players select a perfect square. It may be beneficial to provide students with their previous work including their square table and My Blocks sheet while playing.

If there are no available spaces (for instance all perfect squares have already been claimed) or a student cannot identify a value, they can select "I can't find one!" and play passes to the next player.

Continue to play until a player or team wins!

As with all our digital games, for the best experience we recommend students select full screen mode (this can be achieved by clicking the button in the bottom right corner of the game) and utilize a device with a larger screen such as a tablet, laptop, or desktop computer.
