Review on Math Flash Cards For Kids - Addition, Subtraction, Multiplication & Division With Rings - Kindergarten To 4Th Grade by Gregory Plump

Hapinest Math Flash Cards Set for Kids Hole Punched with Rings - Learn Addition, Subtraction, Multiplication and Division for Kindergarten, 1st, 2nd, 3rd, and 4th GradeThis is a great set of flash cards. The cards are oversized and glossy, and the decks are drilled with a hole in the corner so you can connect them with a ring (the set included 4 rings) and more reliably keep them all together. I say this, coming from a household where I still occasionally find a stray flash card from our last set scattered randomly in the house.I also love that the sets are color coded by function. Addition cards have the problems printed in red, division in orange, subtraction in blue and multiplication in green. This is a nice safeguard for quick sorting, should you get them all mixed up, or a quick visual cue to the required task if you deliberately mix them all up.They're printed on nice thick coated card stock, much like nice playing cards. They're oversized, larger than a standard card deck, like those jumbo senior decks.The cards are nice and opaque. You can't see through them, and even if you could, their clever design would obscure the answers printed on the opposite sides. The cards are designed to look like the problem is written on a little whiteboard, with a marker and eraser sitting in the tray at the bottom. When you hold up the card for your kid, they see the problem in large print, plus small print on the marker shows the answer for the opposite side (the one facing you). You see the other problem (solved on their side) and the solution to the problem facing them on your marker. But the design is such that the solution is printed on the marker, so that from the opposite side, it's covered by the dark eraser, so even if the cards were on a thin paper, the answer wouldn't be visible through the card. Clever! I mean, unnecessary, I guess, given the quality of the cards, but still. Clever.My only criticism is that the solutions (printed on the back of the card you're holding up--so you can't readily see the problem yourself if you're drilling someone) are quite small, and I have to wear my readers to read them. I guess this is so the kid theoretically can't note the answer and then cheat when you flip the card--except that most people shuffle through the deck and flip the whole deck rather than flipping each card--and also, many children have eagle eyes and would have no problem reading the small print. So why not maker it bigger so it's easy on the adults doing the drilling?
