Are you looking for a real-world introduction to your Eureka Math program that energizes and entertains your students while they learn the concepts? Then this PowerPoint program is for you!
In Module 4, students extend their arithmetic work to include using letters to represent numbers. Students understand that letters are simply “stand-ins” for numbers and that arithmetic is carried out exactly as it is with numbers. Students explore operations in terms of verbal expressions and determine that arithmetic properties hold true with expressions because nothing has changed—they are still doing arithmetic with numbers. Students determine that letters are used to represent specific but unknown numbers and are used to make statements or identities that are true for all numbers or a range of numbers. Students understand the importance of specifying units when defining letters. They also determine that it is inaccurate to define k as Karolyn because Karolyn is not a number. Students conclude that in word problems, each letter (or variable) represents a number, and its meaning is clearly stated.
Each lesson is presented with an explanatory slide, then has a slide that asks students to solve a problem. All slides have interesting images; some are interactive!
