How to Multiply by 3 Using Groups and Arrays

MatholiaChannel

A clear, step-by-step instructional video designed to teach students how to multiply by 3. The video utilizes multiple pedagogical strategies, including real-world word problems, visual grouping models, skip counting number lines, and dot arrays to build conceptual understanding before moving to rote memorization. It begins by presenting a scenario with bunches of cherries to introduce the concept of "groups of 3," then demonstrates how to solve it using different methods. The content covers key themes such as equal grouping, the relationship between repeated addition and multiplication, and the utility of arrays (dot paper) for visualizing products. It walks viewers through two distinct word problems (cherries and tennis balls) to show practical applications, concluding with a full recitation of the 3 times table from 1x3 to 10x3, accompanied by visual counters for each step. This video is highly valuable for 2nd and 3rd-grade classrooms as it bridges concrete representation and abstract calculation. Teachers can use it to introduce the 3 times table, reinforce the strategy of skip counting, or demonstrate how arrays represent multiplication equations. The clear visuals and deliberate pacing make it an excellent resource for whole-class instruction or independent review stations.
