PLEASE NOTE: This PDF is exactly the same as my PPT entitled "Math Order of Operations: PEMDAS".
This PDF explains the order of operations in math (i.e. PEMDAS). It includes fun explanations, answer keys, can be used as printable worksheets, examples, PEMDAS summary that can be used in a poster format, and assists with test preparation. It allows your students to practice their key skills.
The PDF contains 62 pages 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 PDF 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).
This resource 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 resource 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.
