Excellent workbook: clear layout, comfortable difficulty progression
Simple, clear layout using different coloured boxes on each page makes it easy to divide the work into concepts, and also to mark good places to take breaks. Sensible progression of difficulty. My 5yo has worked through the first ten pages in comfort and enjoyed learning the different ways to think about each problem.

Good for kids!
I bought this to help my children be productive outside of school, especially during the holiday breaks (can you believe some schools don’t give much homework to students). My children enjoy them, it has a lot of material in here and helps with their learning.

Buen apoyo para reforzar aprendizaje
este libro lo compré para mi hija de 5 años y me parece muy bien ya que empieza desde un nivel muy básico de sumas y restas y conforme va avanzando empieza incrementar la dificultad.
