I love the Kumon books and find them a great supplement to school. With this book, however, I was disappointed to find only eight pages on geometry, involving ONLY triangles and quadrilaterals. A positive is this book covers value in great quantity (counting by tens and hundreds, number place values, filling in missing numbers, greater and less than), which seems to be a good precursor to measuring. Another positive is it covers some measuring, time and money. But I wish there was more geometry. I recommend this second grader book for first graders looking for the above features to review.
