My son used the Saxon 2 Daily Warm Up Worksheets and they made life with 4 boys doing 4 different math levels possible. It just saved me a small amount of time and gave him something independent to do. I was so pleased to see Grade 3. In addition, your customer service is great! You reactivated my Grade 2 warm up sheets so I can use them for my next son! I've recommended these sheets on our local co-op facebook page. :)
