This puzzle is a great learning tool for young children!

I love how each sea animal is labeled, so the puzzle can also be used for early literacy learning. The colors are vibrant & the quality is great! My 3 & 5 year old boys really loved doing this puzzle & keep asking to do it again!

Great way to teach your kids basic science concepts!
I was worried he might lose his concentration nearer the end of the game but he didn't. Just really chuffed that he is already learning the basic concepts of science.
