# Homework Sheets

• #### Year 9 Week 31

This set of sheets moves onto statistics covering: mean, median, mode, range, frequency tables, histograms, reading statistical tables and probability trees. A lot of the work covers these mathematical aspects in everyday activities.
• #### Year 9 Week 32

These sheets carry on with the statistical theme with some graphs to draw and interpret. Which is best for the data presented - a pie graph or a bar graph? You also get to interpret a stem and leaf graph, draw a probabliity tree and look and comment on some misleading graphs. Finally, there is a linear graph to draw and interpret.
• #### Year 9 Week 33

In this set of sheets you get to draw and interpret a probability tree. Learning this skill will be handy for when you move on to higher mathematics classes. A lot of everyday mathematics involves looking and interpreting tables of figures, therefore there is an exercise on what it costs to borrow money. There are then some practical measurement problems and finally you need to interpret the maths on the label of a popular food packet.
• #### Year 9 Week 34

By now you should be an expert at drawing and interpreting a probability tree. You also get to investigate chocolate box packaging and look at Time Series data and graphs. Finally there is a look at a speed-time graph. Remember if you are ever late to school or are not quick enough in class, tell the teacher there was a sign outside that says "School - Go Slow"

• #### Year 9 Week 35

Worksheet Set 35 starts with a signwriting challenge. There is also a ratio and area exercise and a couple of linear (straight line) graphs to draw. There is more measurement and a page of everyday mathematics. Successful students revisit topics often so that they always remember what they have covered. Mathematics is also best learnt by building on your knowledge by using what you have previously learnt to solve new problems.

• #### Year 9 Week 36

This set of sheets recalls your knowledge of area, you get to interpret a fitness graph for two middle aged men, there is statistical data to analyse and then a quick relook at percentages, algebra, equations, expanding brackets and triangle angles.

• #### Year 9 Week 37

A lot of everyday mathematics involves interpreting figures in mathematical tables. In this set of sheets there are tables of repayment options when borrowing money and for paying insurance. There are further exercises in interpreting graphs and an interesting baseball average question. You also calculate which is the best mexapixel option for photographs, investigate the "Rule of 72" and what happens to area and circumference when you enlarge a circle.
