During this unit, students represent expressions in words, with a drawing and converting all multiplication into additions. The main goal is for students to understand each part of the expression and be able to represent it, allowing students to evaluate expressions without memorizing rules.
At the end of each section, worksheets/activities are provided for additional practice and/or homework and should be completed before moving to the next section.
Furthermore, each section builds on the previous one by reinforcing what was learned and adding complexity. Slides are animated and color-coded to help students make connections between the expression and its different representations.
Section 1: Introduces Order of Operation with expressions of the type: A + B x C and B x C + A
Section 2: Introduces expressions of the type: A x B + C x D and A + B x C + D
Section 3: Introduces Distributive property A x ( B + C) and solidifies the concept by adding D + A x ( B + C) and A x ( B + C) + D
Section 4: Focuses on A x B x C
Section 5: Introduces subtraction to expressions of the type A – B – C and A – B + C
Section 6: Adds complexity to subtraction problems by adding the type A – B x C and A x B – C
Sections 7 to 9: Adds complexity by using larger numbers
Note #1: The numbers used is sections 1 through 6 are between 0 and 10 as the focus is on the concept and representations. Sections 7 through 9 extend students’ understanding by using larger numbers.
Note #2: This unit does not include division as division adds a level of complexity that should not be included until students have mastered order of operations with addition, multiplication and subtraction.
Included in this package: PowerPoints (63 slides), PDF file with Teacher’s Notes (guiding questions and teaching suggestions), Activity Worksheets with Answer Keys (total pages 39 without counting answer keys).
The PowerPoint is protected and in show mode. The Activity Pages and Answer Key are in non-protected Word files to allow teachers to make changes for additional practice, review and/or homework.
Important Note: Included in the package are two identical PowerPoints, except one uses the "x" for multiplication and the other one uses "•". Also, all the Word documents use the "x" as multiplication but can be easily replaced by "•" as the Word documents are not protected.
Important Final Note: This package builds on my initial unit “Order of Operation without Memorizing Rules” and the first graphic organizer used is the same. This updated package includes an animated color-coded 63-slide PowerPoint and incorporates larger numbers that can’t be represented. If you are currently using my previous unit, you will LOVE this one!
