Grade 1 - A History Of The Earth

The History of the Earth: Supplemental Guide | Introduction 7

In addition to this core vocabulary list, every lesson includes its own
Vocabulary Chart. Words in this chart either appear several times in the
Read-Aloud or are words and phrases that support broader language
growth, which is crucial to the English language development of young
students. Most words on the chart are part of the General Service list
of the 2000 most common English words or part of the Dale-Chall list
of 3000 words commonly known by Grade 4. Moreover, a conscious
effort has been made to include words from the Primary Priority Words
according to Biemiller’s (2010) Words Worth Teaching. The words on
the Vocabulary Chart are not meant to be exhaustive, and teachers are
encouraged to add additional words they feel would best serve their
group of students.
