Cute little board game for testing whether students can find the HCF and LCM of pairs of numbers.
Works best if you split the class into groups of 2-3. Students must correctly find the HCF (Highest Common Factor) and LCM (Lowest Common Multiple) of pairs of numbers in order to progress along the tiles towards to finish line. The file is editable so you can change the difficulty level to suit your class (and change any terminology if needed)!
Players place their counters at the start position. They roll a dice to determine who will go first (the player with the highest score).
Player 1 rolls again and moves the number of spaces shown on the dice.
If Player 1 is able to correctly answer the question shown, they can stay on that tile. If they answer incorrectly, they must return to their last position (in this case, the start).
Continue taking turns in this way until one player reaches the finish.
And for an added twist, the black tiles:
If a player lands on a black tile and answers correctly, they may move a further 2 places and attempt the question in that position. If this is answered incorrectly, the player must return to the black tile.
Rather than asking for the HCF or LCM of a pair of numbers, the black tiles require students to list all the factors of a number (e.g all the factors of 40).
- Printable (and editable) copy of the board game
- Full set of rules (which can be projected to the class)
What you'll need (per group):
- One dice
- A counter (or similar) each
- A copy of the board game
Please feel free to leave feedback. This game has been a huge hit among my students and colleagues but it would be lovely to hear some opinions from further afield.
