Pictures....ah I love pictures, never would guess that would you? So here are our 2 containers we used. I try to tell kids that size matters in estimation. That things that are larger will appear to be holding less than things that are smaller, but that is not always the case. (depth x length x width)
Here they are really thinking, counting, comparing and ultimately giving me a number that they hope will be accurate. Whoever got the closest to all candies got to keep that jar.
