PAT TEST PREP – MATH

Today we worked on a presentation for our math test prep. We were tasked to complete a couple of questions to remind us of what we’ve worked on throughout the year.

Riveting Revision – Maths

This week we have a maths test, so we were tasked to look through this revision doc. There was work from all the things we have learnt this year.

Self Reflection – Future Aspirations

Our morning consisted of a program called “Future Aspirations”. 6 men and women came into our space. They talked about their careers and their struggles through life. Tyrone, David, Tanielu, Shaniah, Tia and Haare. Afterwards we asked questions about everything they said. The main thing I took away from the talk was: “Don’t be your own barrier” and “It’s better to be an alien than a sheep”. The first one means, don’t think that you can’t do something without trying. The second one means, don’t be a follower be different. I really enjoyed this and was so interested in their speeches.

Graph Conclusions – Maths

We have been working on graph conclusions this morning. There are multiple questions in the presentation, some were challenging, some weren’t. We also had a create task, which we have to complete on the sleeping lions task. Stay tuned to check that out.

Graphy Graphs – Maths

Today we worked on statistics/graphs. The questions were about analysing the data and sharing our findings after looking through the graphs. We also did some critical thinking where we looked at the graphs and shared what we thought could be improved.

Statistical Sleeping Lions – Maths

This is our end product of our statistical investigation! We have finished our analysis, and put in a graph.
