“Four Goodness Sake”

Can you write number sentences that give all the numbers between 0-20 using the number 4 four times? 

This was the challenge posed to some of the students in SNC in math’s workshops during weeks six and seven. 

What followed was a journey where students discovered the concept of squaring numbers , the order of operations (BODMAS), and plenty of practice of their timetable skills.
