This book is great to reinforce letter recognition and ABC order (through dot-to-dots). Also, there is a lot of practice writing upper and lower case letters (much of what would be covered in the "lowercase letters" and "uppercase letters" kumon books). My almost-4-year old enjoys this very much. It also gives me an opportunity to reinforce letters and their sounds in small chunks rather than one at a time, which ends up aiding in ABC order recognition.

Kumon books are great for my 4 year old. He has fun and they really help him learn in small easy steps. Don't sign up for expensive Kumon courses, just get the workbooks- it's cheaper and allows you to spend that quality time with your child.

I am getting my 3 1/2 year old ready for pre-school for the fall, and these workbooks have been so wonderful for us! It helps me have a great teaching guide and he loves the puzzles.
