It is easily adaptable, editable and you can easily create your own to suit your classes needs. I have used the lessons in a variety of ways. Create an overhead and deliver to a whole class in a short time using mental math, put students in small groups and have them present discoveries which leads to some great math discussion or in other ways that suit your class. I have found that my kids are able to increase their mental math abilities at least a full grade level by using the program effectively. I am a big believer in mental math and I try to have my kids use it as much as possible. I find when they find confidence in not using the calculator they start to really like math. Enjoy the program!! Let me know how you find it please.
