Did you know that spending a little time every day thinking through mind-challenging puzzles helps keep your mental processes sharp and agile well into old age? If you like good brainteasers and winning cool prizes as much as we do, we've got a neat little challenge for you to celebrate Train Your Brain Day! We've prepared three mental math/logic challenges designed to get your gray matter thinking creatively—give them a try and send in your solutions to [email protected] by October 23 for a chance to win one of two Mathnasium prize packs!
1. I am a 4-digit number. All of my digits are prime. I am an even number. None of my digits repeat. My tens place is greater than my ones and hundreds place combined. What number am I?
2. Using a 7-minute and a 5-minute timer, how can you measure 9 minutes?
3. You have 9 marbles: 8 weigh the same and 1 weighs slightly more than the others. You have a balancing scale. How can you find which marble is the heavy one with only 2 weighs?
And don’t forget—your brain craves variety, so once you've completed our challenge, be sure to mix up your daily brain training routine with a variety of mindteasers like Sudoku and crossword puzzles. Good luck!
Mathnasium meets your child where they are and helps them with the customised programme they need, for any level of mathematics.
