Great practice for my 6 year old!I bought this book for my 6 year old who is currently in first grade. Over the past few months, he has learned the crossover and carry over method in both addition and subtraction. He has pretty much worked through the Kumon Grade 2 Addition and Subtraction workbooks. This is a great next step for him. He understands and grasps the concept of adding in the hundreds/thousands; however, with the crossover method I am teaching him how to begin subtracting in the hundreds and thousands. We do daily practice in this workbook and he brings it to school to work in during after-school hours. My plan is to have him comfortably doing this addition and subtraction by the summer and during the summer, so that when he enters second grade in the fall, he will be more comfortable with numbers. I also utilize another book called Daily Math 2nd grade as an additional supplement since it has other daily problems such as (measurements, introduction to multiplication and division, fractions, word problems, etc). No I do not home school my son; however, the curriculum at his current public school is not challenging at all for him especially in the subject of Math. I love the repetition and layout of the book. The problems get progressively difficult as the children work the book. As a previous reviewer said, I wish they were able to combine both addition and subtraction problems together…but I can just print those worksheets out at home for free :).
