Incidentally, this reminds me of a scene from a Japanese anime, where a young girl gets her elder sister to explain why 1/2 divided by 1/4 equals 2. The elder girl replies without skipping a heartbeat: you simply invert the 1/4 to become 4/1 and hence 1/2 times 4 equals 2.
The young one isn’t convinced, and asks how on earth it is possible to divide something by a quarter — she reasons you can cut a pie into 4 pieces, but how do you cut a pie into one quarter pieces? The elder one was at a loss, and simply told her to “accept it” and move on.
How would you explain the above in a manner which makes sense?
Would you love to introduce your preschoolers to the mind-stretching wonder of math? Check out Moebius Noodles, an open community of mathematical resources for parents and educators of young children.
Moebius Noodles activities and games use stuff you already have around the house to explore symmetry, fractals, functions, transformations, topology, and more, in a way that is accessible to babies and toddlers (and their parents!) and easily adapted to include older siblings.
Even a small donation will help this amazing project get off the ground — and Maria is offering a variety of “secret rewards” (like free books, or a secret-message game designed especially for your child) to those who chip in now.
To mix things up a little, this month’s Math Teachers at Play Blog Carnival is a love story – between two people and then their new cute daughter. It’s a story of the coolest carnival of all – having kids.
