Looking for a great, concrete way to introduce multi-digit multiplication to your students? Using arrays is a terrific way for students to organize their thinking, concretely show the students what they are actually multiplying when they are working with larger numbers, and help them understand multiplication on a more fundamental level.
In this interactive SmartBoard presentation, students are introduced to the Singapore Math method of using arrays for multiplication. Students learn the concept and apply this method, as they guess what might be behind boxes, and fill in the blanks.
Help your students REALLY understand multi-digit multiplication before they delve into abstract algorithms.
