PLEASE NOTE: This PowerPoint (PPT) presentation is exactly the same as my PDF entitled "Math Order of Operations: PEMDAS (PDF)" - just in a different format.
This PowerPoint (PPT) presentation explains the order of operations in math (i.e. PEMDAS). It includes fun explanations, answer keys, worksheets, examples either as printables or in a presentation format, PEMDAS summary that can be used in a poster format, and assists with test preparation.
The PPT contains 62 slides and the presentation:
- explains what “operations” in maths are;
- looks at why the order of operations in math is important;
- shows what happens if the order of operations are done incorrectly (using examples);
- explains how to do the correct order of operations;
- describes how to remember the correct order of operations with PEMDAS or “Please Excuse My Dear Aunt Sally”;
- provides examples of the correct and incorrect way and explains what to do and what to avoid;
- shows students step by step how to implement the order of operations in various types of math expressions;
- includes order of operations for students to try, with subsequent detailed answer keys to show the students the steps for getting the correct answers using PEMDAS;
- includes examples with parentheses, exponents, multiplication, division, addition and subtraction - with starting with easier examples and working towards more complicated examples - so that this can be used for varying grade levels;
- various worksheets are also included in the PPT with varying degrees of difficulty on different worksheets (answer keys are also provided);
- includes explanations of BEDMAS (for Canadian students) and BODMAS (for UK students).
The presentation is suitable for students from Grade 4 or 5 to Grade 9. It can also be used as revision for older grade students. The examples and worksheets vary in difficulty - and for younger students, teachers can easily remove or delete the slides containing the more complex math expressions.
This presentation could be used to take up a full lesson, or it could be spread over several lessons building on complexity, or sections of it can be used as short revisions during a lesson.
A fun and interesting way for students to learn or revise the order of operations in math.
