Love is in the air, and at Mathnasium, we're all about spreading the joy of learning, especially when it comes to math! As Valentine's Day approaches, we've found a unique way to intertwine the world of numbers with the season of love.
With summer in full swing, kids may not be “feeling” the math lately. In addition to the card games mentioned in the previous blog, we have a math trick that can help your student see how cool math really is! We all appreciate a good ol’ magic trick, especially kids. You might even be a little surprised to see their eagerness and excitement to learn math magic tricks.
This math magic trick is based on a very simple mathematical fact:
Each pair of opposite faces on a six-sided die always add up to seven
In any six-sided die:
1 is always opposite 6, thus the sum is 6 + 1 = 7
2 is always opposite 5, thus the sum is 2 + 5 = 7
3 is always opposite 4, thus the sum is 3 + 4 = 7
So… all you need for this trick is a six-sided die and basic addition/subtraction skills! If you’ve got that, you’re ready for the trick.
Roll the die and once it has landed on a face, gently pick up and turn the die so that the face that it landed on is only visible to the other participant
Tell your friend to memorize the number and keep it a secret
While your friend is viewing and memorizing this number, take the number that is opposite and subtract it from 7
This will give you the number that they are viewing, allowing you to “read their mind”
Say “Abracadabra” and reveal the number
And voila, MAGIC
