My son (Kindergarten) and I have been using RightStart Math level A since September and we are so very pleased with this curriculum. Math was always a struggle for me; but I feel like I’m relearning kindergarten math in such an incredible way! My son is thriving with this program. All of the manipulatives and games are extremely beneficial to him. Every lesson is a new adventure and this program does a great job at keeping things exciting! We are very happy and can’t wait to order level B!
