Grateful Parents Have to Say:
Alison R.
Parent of an 5thGrade Student
My kid has been having difficulty keeping up with math at school. I started doing a worksheet every day when he gets home from school. These are helping a lot in my child's math skills. These are very similar to the worksheets that they use at the Kumon Centers but are it's a lot cheaper to do it at home with my son for now and I would encourage other parent to check out this worksheet at least once to enhance your child math skills.
Claire N.
Parent of Preschool Students
Our 5 yr old twins have been working these worksheets ever since they were 4. They really work. They are basically able to read and write on their own and are already showing strengths in mathematics. They have a reiterative step by step approach which gets more difficult as the child moves farther through the lessons. I would recommend to any parent wanting to get their kids on the right path when it comes to education.
