PEMDAS: Order Up!
Need extra help for EL students? Try the Order of Operations Sequencing pre-lesson.
Students will be able to solve expressions using the order of operations.
- Prior to conducting this lesson, gauge students' understanding of the order of operations.
- Write a pair of equations on the board similar to: 5 × 3 + 6 and 5 + 3 × 6.
- Discuss the rules that must be followed for this problem to be solved correctly.
- Have students insert parentheses around the multiplication or division part in the expressions, and define it as symbols used in mathematics to group things.
- Discuss the similarities and differences in the problems and the change in results this would cause.
- Explain that at the conclusion of this lesson, they will be able to solve problems that require them to know the order in which operations should take place.
- Allow students to use their home language (L1) or new language (L2) in their discussions.
- Provide a definition for "order of operations" and "parentheses" and a visual to help them follow the conversation. Refer to the visuals during your explanations.
- Write the academic language they can use throughout the lesson on the board as you introduce the language.
- Model using comparative phrases and then write some of them on the board to help in their discussions (e.g., "They are the same/different because...").
