Mathematics Faculty

From the Acting Co-ordinator of Mathematics

Happy 2024 and welcome back to all our new and existing families!

Every two weeks in the HouseNews School newsletter, we in the Mathematics Department release our “Problem of the Week” that all members of our School community (parents and carers included!) are invited to participate in. There are two levels of questions: the Green question is a little easier, and the Red question is slightly more challenging. Solutions will be posted in the following weeks’ newsletter.

There are two ways you can submit your answers – either send them in to your Mathematics teacher (or your childs’ Mathematics teacher if you are a parent!) or you can also send answers in to maths@tphs.nsw.edu.au 

At the conclusion of each term, the individual who sends in the highest number of correct solutions will receive a $10 iTunes gift card.

Happy problem solving everyone!

GREEN PROBLEM:

Your friend tells you that they have two bills in their pocket and the bills can only be $1, $5, $10 or $20 bills. How many different amounts are possible, in dollars, that these two bills could consist of?

Note: both bills can be the same.

RED PROBLEM: 

Edith had nine children at regular intervals of 15 months. If the oldest is now six times as old as the youngest, how old is the youngest child?
