What I love about Brainsmith’s Quantum Cards:Great quality cards. BabyT has bent, sat and folded the cards in a million ways. But they don’t really get bent too badly. This is because the paper itself is of a superlative quality.The images are so artistic and professionally drawn. Brainsmith says all the images are licensed and hand drawn and painted. The fine work shows and is a true reflection of what that object must look like in real life.The cards themselves are huge. The images therefore are large and contrast well against the clean, white background. This helps create a visual impact on the mind. It stimulates visual learning. When the different senses are used to learn, the learning is more permanent.The information provided behind each card is succinct and will suit younger children as well as older ones. I am sure we will keep finding new elements about each animal as babyT grows up.Each set contains 10 cards which is good for a one time learning activity. Other flash cards sets that I have, had like 20 to 30 cards and even I found it too boring to go through them all. I also love the summary card which has images of all the mammals on it. BabyT loves reading and pointing the animals out on his own here.
