This app is simple but sweet. It helps groove a child into the various basic consonant blends that many words in the English language start with and allows them to practice forming words using them. This app covers 20 consonant blends such as br and th. For each consonant blend, the child plays a game to see if he can form 5 actual words correctly using this blend. It is a great way to learn and practice spelling. Once the child gets 5 correct, he can move on to any of the other consonant blends of his choice. It is a great learning tool.
