Measures of Centre Teacher Resources for Years 5 to 10
Everything you need to teach mean, median, mode and range — lesson plans, worksheets, slides, a question bank and assessments. Aligned to the Australian Curriculum v9.0 for Years 5 to 10, and ready to differentiate for the range of learners in your classroom.

What's Included in the Resources for Measures of Centre?
🔥Curriculum Aligned
Built around the Australian Curriculum v9.0 statistics strand, the pack covers calculating the mean, identifying the median, finding the mode and choosing the most appropriate measure for a given data set. Worked examples use familiar contexts — class test scores, sports stats, household budgets — so students see why each measure matters.

🌍 Differentiated for Students
Each resource ships in three difficulty levels so you can stretch confident statisticians and scaffold students who are still cementing place value and ordering. Worksheets include simple, ungrouped data for Years 5 and 6, frequency tables and stem-and-leaf plots for Years 7 to 9, and grouped-data and outlier analysis for Year 10.
💡Incredible Teacher Resources
The pack moves from procedural fluency — calculate the mean of this list — to interpretation: which measure best represents the data when there's a clear outlier, and what does that tell us? Higher-order questions ask students to defend their choice of measure, a skill that flows directly into Year 11 General and Methods.

Interactive Resources
Practice Questions
Worksheets cover ungrouped data, frequency tables, stem-and-leaf plots and grouped data with class intervals. Each set includes a warm-up, a fluency strip, an applied task and a stretch question, so a single resource can support a full lesson or be sliced into starters and exit tickets.
Structured Solutions
Differentiated Questions
Practice questions ramp from one-step calculations of the mean of five values up to multi-step problems where students compare two data sets and justify which measure of centre tells the truer story. Solutions are fully worked so you can mark in minutes or hand them straight to students for self-review.
Real-World Applications
Engaging Exercises
Real-world tasks anchor each measure in something students recognise — Year 7 students compare the median price of a streaming subscription across providers, Year 9 students use the mean to interpret cricket batting averages, and Year 10 students explore how outliers in census data shift the mean but not the median.

What Do These Measures of Centre Resources Cover?
Mean, Median, Mode and Range — the Core of Statistics
Choosing the Right Measure for the Data
Outliers, Skew and Stretching Year 10 Students
The pack covers the four measures students meet across the Australian Curriculum v9.0 statistics strand: mean (the arithmetic average), median (the middle value of an ordered list), mode (the most frequent value) and range (the spread from lowest to highest). Lessons build from concrete examples — a row of test scores, a tally of favourite sports — up to working with frequency tables and grouped data. By the end of the sequence students can calculate each measure, interpret what it tells them about a data set, and explain the relationship between measures of centre and measures of spread.
Knowing how to calculate the mean is one skill. Knowing when the mean is the wrong choice is a more advanced one. The resources include comparison tasks where students look at two similar data sets — one with an outlier, one without — and decide which measure of centre best represents each. Real contexts help: median house prices, mean rainfall, modal shoe size. By Year 9, students should be able to argue from the data, not just compute from it, and the worksheets give them the structured practice to get there.
For Year 10 classes, the pack pushes into outliers, skew and the limits of each measure. Students work with larger data sets drawn from sport, finance and population statistics, calculate measures of centre with and without outliers, and discuss the effect on the mean compared with the median. These tasks set up the formal study of standard deviation and statistical inference in Year 11 General Mathematics and Methods, and give students the reasoning habits they'll need for senior data analysis.
