PEDMAS codebreaker activity
PEDMAS Activity
Make using PEDMAS fun with this code-breaker game. Students are asked to use the correct order of operations by using the PEDMAS (BODMAS/BEDMAS) rules to answer simple arithmetic problems.
In this simple PEDMAS game, there are no exponents. Only addition, subtraction, multiplication, division and parenthesis.
The code is random to avoid your students attempting to guess a riddle rather than 'do the math'!
Make it more engaging by offering a small reward for the first student to crack the code. This makes a great spiral review activity.
What do the letters in PEMDAS mean?
PEMDAS is used as an acronym for the words parenthesis, exponents, multiplication and division, addition and subtraction. It is the order of the letters in PEMDAS that tells you what calculations to perform in the correct order.
The phrase Please Excuse My Dear Aunt Sally has often been used to help students remember the order of the letters in PEDMAS.
An example of the use of the word PEDMAS:
Work out
9 + (3 × 13 + 2)
Pedmas tells us to start with any operations grouped in parenthesis first, so we would start with working out
3 × 13 + 2
Pedmas also tells us that we should do multiplication before addition, so this becomes
39 + 2 = 41
Now we have dealt with the parenthesis, we have reduced our calculation to
9 + 41 = 50
