40 structured lessons. Lessons are grouped by subtopic.
Grade 4 science (4th grade, ages 9–10) is 40 lessons in 5 units: Unit 1 — Life Science (lessons 1–8), Unit 2 — Earth Science (lessons 9–16), Unit 3 — Physical Science (lessons 17–24), Unit 4 — Human Body and Health (lessons 25–32), and finally Unit 5 — Projects and Review (lessons 33–40), project work that brings the year together. Along the way, children learn to distinguish between renewable and nonrenewable resources, define reflection and refraction of light and explain what nutrients are and why the body needs them.
Start here: Lesson 1: Compare Plants and Animal Adaptations is free to open and print. Every other lesson has a free preview of its mini lesson and vocabulary.
Paper first: each lesson is printed before you call your child. You read it once and talk it through, your child does the exercises on paper, and you correct together with the Parent checklist — about 45 minutes at the table. The next day, a 10-minute screen review of the same lesson.
