Elementary Math Algorithms is your answer to the explanation of math algorithms used in grades 2-6. It contains 26 interactive slides for demonstration and practice along with links to videos for further explanation. Also, included is a math cast created by a former 5th grade student of mine explaining how to do Lattice Multiplication with Decimals. The algorithms covered include; Lattice Multiplication, Partial Products, Column Addition, Partial Sums, Trade-First Subtraction, Counting-Up, Partial Differences, Partial Quotients,
Column Division, and Traditional Long Division.
