Another problem with almost all worksheets is that they don't prevent incorrect answers. Self_checking worksheets just let the student know they did something wrong__after the fact. I am a firm believer in the concept that, if at all possible, learning should be structured in small chunks in such a way that there is very little possibility for error. Worksheets often allow for mistakes to be made and then to be repeated many times. A mistake that gets practiced is extremely difficult to correct. This especially happens when worksheets are used as time fillers or baby sitters and the work isn't really being supervised.
Step 3: Flashcard Ward I have my son in a competition against my husband. I write the problems on flashcards. Whoever answers it first, gets a point. Off course my husband takes his time and makes sure to just stay within a point or two of my son. This is honestly the most effective step for my son. He tries so hard. I started offering prizes for the winner. Nothing big, you have to see how hard an eight year old will work for a cookie. When we complete these steps, he is ready to go! It has been extremely effective for Cameron. He started the school year with a 2 out of 4 as a math skill grade. His last report card just came and he is now on the 4 out of 4 level. I hope it helps you too!
