Yes, it says "K & Up"—and yes, it still belongs in your Pre-K kit.This workbook covers science concepts your Pre-K learner is ready for, including living and nonliving things, life cycles, the five senses, weather, seasons, landforms, rocks, moon phases, textures, forces, and phases of matter. While Kumon labels it "K & Up," the difference is less about the content and more about the level of independence it expects.Like every Kumon workbook, lessons begin simply and build gradually, helping your child master one concept before moving to the next.For Pre-K students, we recommend working through this book together. Read each science fact aloud, talk about it before placing the sticker, and enjoy the mazes, matching activities, and coloring side by side. That little bit of parent involvement makes this workbook an excellent fit for younger learners.We selected this workbook because Kumon's gentler Pre-K & Up science title is now out of print. With a parent alongside, this edition provides the same incremental Kumon approach while giving your child a strong introduction to early science.
