When I bought the math book for 1st Grade, I loved it so much, that I ordered Grades 2, 3, 4 and 5. I am very happy to see how my son is excited to do his math homework now! Great choice for home schooling kids as well. You can use this book as extra math work for your kids, let them think, count, draw and even color funny illustration this book filled with. It has 600 questions and almost 300 pages! HIGHLY RECOMMEND.
