This is one in a large series of short videos from NCETM showing how people use maths at work. See the others here.
Here is a great phone app that will help you with your arithmetic so you don’t need to be afraid when you are faced with that non-calculator exam. It’s called Maths Tricks and shows you lots of short cuts to performing calculations and gives you endless practice to improve your speed and accuracy. Best of all it’s free!
You can find it on Google Play. I am recommending this because it is good, not because I have any connection to the app.
Equipment. One pack of cards with picture cards removed.
The black cards are positive numbers and the red cards are negative numbers. Ace is one. Each player is dealt 2 cards. Each player chooses whether to accept a third card from the dealer. The object is to make the total of the cards in your hand as close to zero as possible. The hand shown on the right is +7.
Each round the winner scores zero and losing players score the difference of their hand from zero. The pictured hand would score 7 points.
Play continues until one player reaches 50 points. The winner is the player with the least points.
An arcade style “astroids” game where you have to shoot the decimals in the right order.
Download, print and cut out the triangles. Work with a friend to try and match all the questions with the correct answers and make a shape.
