Katherine Johnson Multiplication Word Problems - Christy Walters | Biblioteka

Instrukcije

Celebrate Black History Month while practicing multiplication and multi-step problem solving inspired by mathematician Katherine Johnson. This short quiz (9 questions) includes single- and multi-step multiplication problems, table interpretation, estimation, and a short reflection connecting math to real-world space work.
