Math for elementary school children with problem solving worksheets, drills, addition, subtraction, division, multiplication, counting, number sense etc.
As former elementary science and math education professor, I was always encouraging preservice teachers to teach science and math from a hands-on, minds-on perspective.
My goal was single minded in the sense that for students to learn science and math their curiosity must peaked.
This was always a challenge because most of these preservice teachers learned science and math by rote memorization of facts. Their prior knowledge and experience had few opportunities to actually investigate science phenomena and truly understand the usefulness of math.
Teaching math to elementary students is critical for establishing a foundation of success in mathematics. There is a need for some basic memorization of facts, because students who do not memorize arithmetic functions struggle in upper grades.
However, math must be fun and interesting, along with making connections with real-world applications.
