After finishing book 1, I was pleased with the results. My struggling speller was spelling and reading!(thanks to the combination of AAS and the Beehive Reader), and I was pleasantly surprised to see the other two gain confidence with their spelling.
So if you are looking for a new spelling curriculum, I would highly recommend All About Spelling. If you are currently using AAS, don’t forget that AAS Level 5 is now out. If you would like to know more, there is a helpful community called the ChatterBee that can answer any questions you might have.
