This little packet is great for traveling, or educational activities on the go. You don't have to be only using it for the CVC words that are included, but can use it for spelling practice, or expand your set on your own. We are teaching our little one to read and the hands on activity that doesn't slip or get away from your too easily (because of the magnets) is a great help. I do wish the letter tiles fit a little more exactly. On the width, exactly 3 letters fit across. On the length, it fits several letters with a space just slightly too small to fit one more. and then the stack of letter is a little more than the height of the container. If you are type A or need all your ducks in a row, this might bother you. But if you are a kid who would not have put it back in neatly anyway, should be fine. The good news is that the lid fits on top of this securely. Love this kit, love the value, love the versatility. Ok Ok it's just travel magnet letters, but it just works for where we are in our word family journey
