My son is in second grade and I was not happy with the math book we had been using the year before so I decided to give this book a try. We both love it. It is challenging but it incorporates multiple exercises so that he doesn't get overwhelmed. We will be using Horizons next year!
My daughter loves these workbooks. They are colorful but not distracting or full of sensory overload. I have seen some workbooks that are to full and overwhelming. I am planning on using these up to the 3rd grade and then switching to Saxon in the 4th grade and so far these have been an exellent math workbook preparing her for her older years.
Each daily lesson has a review of the same material of the previous day. At the end of the week there is a test. The next week starts off with the same material a bit harder and harder or it will add a new topic.
My 7 year old son LOVES math! Horizons math has been perfect for him, as it has cute colored pictures and moves along at a quicker pace. He excels at Gr. 3 level multiplication/division tables, and so finding that in a level 2 book is great. I do think, unfortunately, that for the average Gr. 2 child, the Horizons Math would be too difficult ... but if you have a math lover, then this is the book series for you!
