Playing Card Maths

Imagine you are on a desert island with nothing but a pack of playing cards. Do you have to stop learning mathematics? Of course not! Here are some great ideas for teachers, parents and tutors.

Learning the sequence of doubling numbers (powers of two) is a worthwhile pursuit for children of all ages. This game is lots of fun to play, does not require the player to already know the doubling sequence, but presents the numbers in context and in a way that will help the child learn and recognise them.

Play the game little and often! Do not spend hours and hours playing but do spend ten minutes every day working to improve your score. Your personal best score is shown at the top right of the screen and this provides a target for you to try and beat. Earn trophies as you achieve the high score tiles.

Enjoy playing the game and learning more mathematics as you do.

Comment recorded on the 9 May 'Starter of the Day' page by Liz, Kuwait:

"I would like to thank you for the excellent resources which I used every day. My students would often turn up early to tackle the starter of the day as there were stamps for the first 5 finishers. We also had a lot of fun with the fun maths. All in all your resources provoked discussion and the students had a lot of fun."

"An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!"

"Keep in mind you can achieve numbers higher than 2048 I have actually managed to reach 4096. The language used on the webpage implies the game ends after reaching 2048 and trophies aren't tracked for numbers higher than 2048 and this all irks me."

"Keep in mind, you can get 128 by random swipes, but that is quickly game over."
