Anyone else's kid have particular trouble with the "packing boxes" game intended to teach place value? DD6 mostly gets place value, but is totally thrown by questions like:
There are 52 items. Fill in the missing values.
Boxes.......Loose Items
3.............22
__............42
2.............__
Anyone else got stuck here? Ideas on how to explain it?
(I have a suspicion DD is stuck because it's a complicated way to represent something simple. Like, if you're grouping tens, why did you stick some of them over on the "boxes" side and some of them in the tens place on the "loose items" side?)
