My 2.5 grand daughter caught on to the color matching pretty quickly. When she completes the cups for a card, she loves to ring the bell. HA! The quality of the cups, bell & cards is really good. These cards wont rip. I like the variety of color arrangements on the cards. As they learn the stacking and in-a-row cards, they can move on tho the more challenging spacial placement cards. I can see this being a very useful learning tool for a few years. I will say, I thought it was a bit pricey for what you get, but the learning opportunities make it worth it.
