Singapore Math 3 Books Set for Grade 2 - Singapore Math Intensive Practice 2A & 2B, Challenging Word Problems Grade 2

I used these textbooks long time for my kids. From my older son to my daughter to my younger son. A lot of excellent traditional math questions and tricky methods to explain the solutions. That is great supplement for my kids on mathematics.However, compared to another textbooks called monster academy, the solutions in these books are too simple and too abstract for elementary students. Parents need help to explain to them. If they can update the explanation of solution I would like give them 5 stars

I like the book, it is for for my baby
