I have been using these worksheets from “Home-Skool Mama” math book with my second graders and they love it. We use it daily. What I like most about it is all of my students regardless of their math level can work with and be motivated by doing better each time through repetition. Also the the way it progresses and challenges them when you use a timer. Students who are challenged by math and students who are advanced in math can use this book effectively.
