Mastering Extended Multiplication Facts

In this math class, students build on their multiplication knowledge by practicing extended facts. The teacher introduces manipulatives like cubes, longs, and flats to help visualize multiplication. Basic facts such as 2x3 are used to explain extended facts like 2x30 and 2x300. Students practice these concepts with examples like 3x5, 3x50, and 3x500. The class concludes with additional practice problems and an invitation to complete assignments on IXL and a logic puzzle challenge.
