Assessment Task Plan

Year 7 Mathematics How Fit Are You?

Unit overview

This unit requires students to understand what data and mathematical calculations are required to make judgements about one’s personal fitness. Records of students’ physical activity, including heart rates and recovery times, are used to prepare tables and graphs that illustrate levels of fitness. The calculation of mean, median and mode will assist students to make statements about their own personal fitness and to make comparisons between their level of fitness and that of the whole class.
Curriculum intent
Ways of Working
Select and use suitable mental and written computations, estimations, representations and technologies to generate solutions and to check for reasonableness.
Evaluate thinking and reasoning to determine whether mathematical ideas, strategies and procedures have been applied effectively.
Communicate thinking and justify reasoning and generalizations, using mathematical language, representations and technologies.
Reflect on and identify the contribution of mathematics to their life.
.
Knowledge and Understanding
  • Data can be summarised and represented to support inferences and conclusions
  • Measures of location such as mean, median and mode, and frequency and relative frequency, can be used to explore distributions of sample data
  • Sample data drawn from a given population can be summarised, compared and represented in a variety of ways

Reflecting
What deep understandings are desired?

The desired result is for learners to understand that:

  • Mathematical data, in the form of activity rates, heart rates and recovery time, can be used to evaluate personal fitness levels
  • Measures of location can be used to support inferences and conclusions about data
  • Representations of data, such as tables and graphs, aids used in interpreting a range of data
What essential questions will guide the inquiry?
  • What data and mathematics can I use to determine a report about my overall fitness?
  • What mathematical calculations will be useful in analysing my fitness?

What key knowledge and skills will students acquire as a result of this unit?
Students will know:
  • Rate is a comparison of two different measurements e.g. heart rate and recovery rate
  • Tables and graphs can be used to display data
  • Mean, median and mode are measures of location
  • Sample data can be summarised, compared and analysed
Students will be able to:
  • Calculate their heart rate before and after an activity
  • Calculate the speed of recovery after an activity
  • Create a table and record raw scores
  • Choose a suitable graphical representation and convert data tables into graphs
  • Create a frequency distribution chart
  • Check the reasonableness of calculations
  • Make inferences and draw conclusions from the data
  • Make statements about using mathematical calculations and graphs to describe aspects of daily life

Assessment – what evidence of student understanding is needed?
  • Record raw scores as a data table
  • Create a frequency distribution chart
  • Calculate mean, median and mode
  • Create graphs from the table data
  • Make inferences and draw conclusions using the data and mathematical reasoning

Assessment task outline
The assessment will require students to present a personal report which includes tables and graphs showing their overall fitness. The report should display mathematical calculations of mean, median and mode and frequency distributions of class scores which provide information from which comparisons and conclusions can be made against personal scores.
Literacy demands:moderate
Numeracy demands: The meaning of rate. Conventions used when constructing tables and graphs. Mathematics concepts that will be useful when analysing data.
Explicit teaching required
  • Discuss how mathematics might be used to help you determine your fitness level
  • What mathematics might you need to do?
  • What data might be useful?
  • Calculating heart rate and speed of recovery
  • Displayingdata in different ways including tables and graphs
  • Calculating mean, median and mode
  • Making inferences and drawing conclusions using mathematical reasoning and information from tables and graphs
