This is a solid curriculum that has helped close the gaps that my son has in the foundations of Math. This is well suited for children like our son who respond well to multi-sensory types of learning. While there are families who may feel that the curriculum does not do enough “Drill” type of exercises, the choice is their own to supplement that type of reinforcement with RightStart Math. I did not realize how well the right type of game could reinforce number sense and math facts. This curriculum is worth every penny and there is no turning back for us!
