In my personal opinion, Pearson's teaching materials have a higher utilization rate, and many treasure mothers like to use them for their children because the contents in them still meet their preferences.

Pearson English:

The compilation of Pearson children's graded English reading is based on an authoritative survey. According to the survey, in English, 12 words account for 25% of our total reading vocabulary, 20 words account for 10%, and 68 words account for the remaining 20%. This means that in English, only 100 words account for 50% of the words used in our lives.

A set of English graded reading picture books can cultivate children from parent-child reading to independent reading, meet the English learning needs of children aged 3- 12, grasp the golden period of children's language learning, adopt a rigorous and scientific grading system, easily and effectively improve children's English level and stimulate children's interest in English learning.

Oxford Tree English:

Oxford Reading Tree, English Oxford reading tree, is a reading textbook published by many children's reading education experts organized by Oxford University Press in the United Kingdom after more than 20 years of continuous research and development. This is an educational English reading book for children, which is aimed at preschool children and primary school children whose mother tongue is English.

Including stories, poems, audio books and interactive games, which are attractive to children. Oxford Reading Tree is a well-known English mother tongue learning material in Britain, and has the reputation of "the most popular reading plan in Britain".
