Young scholars use desk arrangements to help them learn about factors, arrays, and commutativity. In this multiplication lesson, students read a multiplication problem about student desk arrangements. Young scholars then brainstorm a solution to the problem and watch the QuickTime video about the topic. Students complete the Commutative Operations handout and discuss. Young scholars may complete a factor pairs activity and a rectangular prism activity.
A restaurant scenario starts this lesson, getting students to think about doubles facts as equal groups that can be added or multiplied. Throughout the course of a week, pupils will use manipulatives, write word problems, and play flash card games to construct a solid understanding of the principals behind all multiplication. Note: Taking time to let learners explore and fully understand the fundamental principals behind any mathematics concept is the best way to foster success.
Fourth graders play a game with red and green cards (composite and prime numbers). As a card is drawn students create all possible arrays. The winner of each round is the person with the most arrays. Students discuss their results, and define the terms prime and composite.
Sixth graders explore probability through experiments using lists, arrays, tree diagrams, and station games. In this theoretical probability lesson, 6th graders use a tree diagram to find probable outcomes in an experiment. Students then rotate through stations, playing theoretical probability games. Students determine if the games are fair or biased.
