Start English from the Basics
The most effective way to learn English for children is to approach written text by learning what they sound like. After this, learning sentences and grammar will feel a lot easier for children.
This series not only covers the usual consonant and vowel phonics, but also digraphs, vowel sounds, comparisons of similar sounding phonics and phonics that are used in similar places.
Each book contains repetitions of the phonics sound and sentence format in interesting stories, making it easier for children to remember. The series also comes with workbooks and a guidebook to help children with the learning process.
