KaBoom cards are designed to be played as a whole class or small group activity, and is fully differentiated.

These cards are designed to test finding factors and multiples of numbers, starting with simple factors and multiples that can be found by listing (red cards), moving on to harder factors and multiples that require using prime factors (yellow) and finally more challenging prime factor questions and some questions involving finding the highest common factor or lowest common multiple of three numbers. 

Begin by laying all the cards out face down (so you see only the number of points they are worth). Players take turns to select a card, either red, yellow or green. The difficulty of the questions will increase. They may also pick up either a Steal Card, giving them a chance to steal from any other player, a Shield, which protects them from the next KaBoom, and KaBoom cards which means you lose all your collected points so far.

Play as a whole class in teams, or print multiple copies to play in small groups around the table. If students get the answer incorrect, or they need some help, you as the teacher decides whether you will allow them another guess or not.

Questions answered incorrectly go in the ‘house’ pile, along with any cards lost in a KaBoom. At the end of the game, add up the ‘house’ pile. The winner is the player or team with the highest points (including any shield cards that have been unused). The house can win.

Play ends either when all the KaBoom cards have been played, or after a set number of cards are gone, or after a given number of turns, your choice. If you play until all the KaBoom cards are played, then at least one team most likely will end up with no points. 

Included are two copies of the game; one designed for a double sided printer and one designed for single sided printing where you need to turn over the pages yourself to print double sided.

Full instructions are included as are answers. A UK and US version is included for the terminology.

This is a digital product. A download link will be sent to your email address upon purchase and you can then print as many copies as you need to use in your classroom or for home use.
