Return of the Math Vines

In a previous post I shared some Math Vines that I have created with my colleagues Chad Richard and Dan Allen. Here are some others we have recently made. The first one which develops the area of a trapezoid formula has proved to be very popular (and, we think, is much more beautiful than our original attempt which is below it).

We do like using Vines to show why formulas work. The next one was actually inspired by brother-in-law, Stuart Sudlow, who is tech teacher for TDSB.

Vines can also be used to develop a concrete understanding of things such as fractional equivalence.

Or Vines could be used to prove things through spatial reasoning:

Or reveal hidden mathematical gems:

Finally, look at this Vine and ask yourself where the missing square went:
