Unit planner Assessment rubric This rubric aligns with Year 7 Australian Curriculum: Mathematics, is the focus of this unit. Teachers may wish to expand to include other learning areas. This rubric is intended as a guide only. It can be modified to suit teachers' needs and to be integrated into existing assessment systems. Teachers may also wish to collect the worksheets as work samples for individual student folios.

The student provides a succinct and thorough justification of their solution The student selects and uses appropriate mental and written strategies to calculate ‘best buys’. Occasional errors are corrected with little or no assistance. The student provides acceptable justification of their solution The student selects and uses some basic mental and written strategies to calculate some simple ‘best buys’. Justification is unclear or not provided The student can apply the unitary method to identify ‘best buy’ situations, such as comparing the cost per 100 g See ACMNA174 above Activity 2 Worksheet 4 The student selects the correct pricing units for all grocery items and accurately calculates their unit prices The student selects the correct pricing units for most grocery items and calculates their unit prices. Occasional errors are corrected with little or no assistance The student requires teacher guidance and support to select and calculate the correct pricing units for grocery items

The student makes some valid comparisons between several prepaid plan offers and provides a recommendation with some justification for the best one based on needs and budget The student records given estimates of mobile phone and data usage. The student requires teacher guidance and support to make simple comparisons between several prepaid plan offers. A recommendation is provided with unclear or no justification
Assessment rubric (cont) Skill Relevant content description(s) Relevant activities and worksheets Competent Developing at Needs further development The student can explain and apply their learning by recommending ways in which spending can be reduced Suggested Summative Assessment ACMNA156 ACMNA174 ACMSP169 Activity 5 Worksheet 8 (includes assessment criteria) The student: provides a clear and detailed explanation of a practical strategy for saving money comments thoughtfully on the pros and cons of the strategy researches cost differences thoroughly calculates correctly the potential savings over a 6-month period explains calculations clearly and includes unit calculations where relevant creates a well- designed, detailed and imaginative poster The student: provides a satisfactory explanation of a practical strategy for saving comments on a few of the pros and/or cons of the strategy researches some cost differences calculates, with some errors, the potential savings over a 6-month period explains most calculations and includes some unit price calculations where relevant creates a poster that organises and displays most information satisfactorily The student: provides minimal explanation of a practical strategy for saving money comments on one or two of the pros and/or cons of the strategy researches little about cost differences attempts to calculate the potential savings over a 6-month period, but has little success provides little or no explanation of calculations creates a poster that lacks detail and organisation
Collect the PMI charts and note students’ understanding of the considerations involved in comparative shopping. As homework, ask students to discuss with their parents areas of the family budget where some savings could occur. Each student should write a list of at least five expenses where they and their family feel some money could be saved by changing spending habits. (If it is considered to be too intrusive for your students to ask about household budgets, you could provide an alternative task – identify, with their parents’ help, how savings can be made in a supermarket context by identifying five products where money could be saved by changing their spending habits. NOTE – if making this alteration, you will need to adjust the culminating assessment task, outlined on Worksheet 8: Smarter spending. Notes The ABC program ‘Checkout’ is an excellent resource for developing competence in consumer and financial literacy. Start collecting advertisements and catalogues with prices of groceries – perhaps send a letter home to ask for these. Activity 2 Examine how unit prices are calculated Unit prices are on the most appropriate unit of measurement, which is usually written on the packaging. Students can look at unit pricing in real terms by visiting a supermarket or finding online grocery catalogues using the search ‘supermarket specials Australia’. The ACCC provides guidelines for unit pricing. Students work in pairs to answer the questions below. The ACCC website address is . What does ACCC stand for? What is the purpose of the ACCC? Students type ‘grocery unit prices’ into search engine then read the information online to find the unit that would generally be used for products with the following quantities. Quantity Unit 365 g 100 g 250 mL 100 mL 3.5 L 2.3 kg Briefly discuss students’ responses to these questions in class. Read through Resource 1: Unit pricing with the class. The handout models the calculations used to find unit prices. It is often reasonably simple to estimate an answer. For example:
