Introduction
(5 minutes)
Write PEMDAS in large print on the board, along with the definitions and symbols: P (parentheses), E (exponents), M (multiply), D (divide), A (add), S (subtract).
Tell students that it is important to know the proper order of operations so that we are all consistent with our answers.
Show students 'The Order Of Operations Song' by Silly School Songs on a video projector or tablet.
