During one of my recent 20 minutes of math play sessions with my 5 year old daughter, we played around with a number line. A number line is a really abstract thing, and without something to connect it to, it is nearly impossible for a young learner to understand. So we built this fun thing:
That got me thinking that maybe we could build one that didn’t use similar sized objects for a number line, to help her understand that a number’s value will still be the same even if the object is a different size. That was when we came up with this one:
All of this building led to talk about sizes of things, grouping things, ordering and reordering, the value of numbers and so much more. It was a ton of fun to make both with the number representations and actual concrete objects!
