This week for homework I gave students a mathematical challenge of four numbers to work with in BODMAS to produce as many different combinations they could fit on a page in their book. They need to do a minimum of three and maximum of four numbers in each combination.
Scoring for this was
For Three Numbers
If addition and subtraction are only used – one point
If multiplication is used – two points
If division is used – three points
If brackets are used when needed – three points
If four numbers are used they get an extra point added on
Example Addition and subtraction are now – two points
At this stage we don’t want negative numbers or remainders with division or fractions in their answers. Answers have to be whole numbers.
Hope this makes sense.
