Featuring content from Funk & Wagnalls New World Encyclopedia, Primary Search provides students with easy-to-read encyclopedic entries written specifically for kids. All full-text articles are assigned reading level indicators (Lexiles) that provide educators with an estimate of the result’s reading difficulty and the approximate grade-level reading ability required for comprehension. Lexiles help teachers meet the needs of students with varying reading abilities and interests and allow students to read along at their own pace.
