What's in the Third-Grade Kit Third grade is where independence starts to build. Your child will read full literature selections, start cursive handwriting, and tackle multiplicati on. History moves into the early modern era, science deepens across all five disciplines, and thinking skills shift toward more abstract problem-solving — logic puzzles, strategy games, and multi-step challenges. STEM this year includes a marble-run engineering set that tends to take over the dining table. Classic and nonreligious kits include the same materials at this grade — compare tiers below to see what's in each, and use the customizer to swap anything that isn't the right fit. Show more
