# When Game Time Is Any Time

June 28, 2015

Do you know how to tell time? If you have a digital clock, the first number tells you how many hours have passed since noon or midnight, and the second number tells you the minutes since the hour started. But Bedtime Math fan Talie B. just showed us a new clock that turns telling time into a game. Instead of just saying 9:32 am, for each number it gives you an “equation,” or a way of combining other numbers. So it might say 3+6 for the hour (9), and 8 x 4 for the minutes (32). Better yet, it changes to a new equation every time, and it can use adding, subtracting, multiply, dividing, or even more than one of those at once. We’re guessing it’s named the Albert Clock after Albert Einstein, because you have to use your brain…if you do that every day, you’ll become really smart just like Albert!

Wee ones: If the Albert Clock says 7+1 for the hour, what hour is it?

Little kids: If it’s 4:00 and the clock uses a 2 and a 6 to tell you the time, what would it have to do to them?  Bonus: What other number of hours could you make with just a 2 and a 6?

Big kids: Can you find a way to combine 5, 4 and 7 to get 31?  Bonus: What’s the biggest number of minutes you can make with 2, 7 and 8? (Reminder if needed: the minutes part can run only as high as 59!).

The sky’s the limit: How many ways can the clock show 12 by multiplying 3 digits?
