From the Mathematics Faculty

Happy 2023 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’ HouseUpdate.

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!
