Every year April is Math Awareness Month! Let’s celebrate with a fun video for you on math in real life. In “Ninja Training,” we meet Kevin, a guy who will try any job but is almost never good at it. Why? Because he doesn’t do the math right. Watch what happens when he tries to be a sneaky ninja and it all goes wrong. (Parents: You might want to check out the video first before showing to your wee-est ones.) Click here to watch!
Wee ones: Kevin has to sneak through windows. What shape is the window in your room?
Little kids: To reach that window, Kevin climbs a ladder. If he’s climbed up the first 3 rungs, what numbers are the next 3 rungs he climbs? Bonus: If there are 10 rungs total, how many does he have left?
Big kids: If Kevin takes 12 seconds to climb the ladder and 1 second more than that just to fall through the window, how much time does that take in total? Bonus: Can he then make a 28-second run down the hall and finish it all in under 1 minute? (Reminder if needed: A minute has 60 seconds.)
Wee ones: Most windows are rectangles or squares, but yours might be an oval or other shape.
Little kids: 4, 5, 6. Bonus: 4 more rungs, since he’s climbed 6 out of 10.
Big kids: 13 seconds, since he takes 12 + 1. Bonus: Yes! He will take 13 + 28 = 41 seconds total.
Laura Bilodeau Overdeck is founder and president of Bedtime Math Foundation. Her goal is to make math as playful for kids as it was for her when she was a child. Her mom had Laura baking before she could walk, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
