Activity 01
Role-Play: Chef Recipe Scale-Up
Provide groups with a recipe for 4 servings. Students use fractions and ratios to scale it for 20 people, then add decimal costs for ingredients from a price list. Groups cook a sample and present their calculations. Discuss adjustments for time constraints.
Explain how a chef uses fractions and ratios to scale a recipe for 100 people.
Facilitation TipDuring Role-Play: Chef Recipe Scale-Up, circulate with measuring cups and recipe cards to guide students through scaling while emphasizing the role of fractions and ratios.
What to look forPresent students with a simple recipe for 4 people. Ask them to calculate the ingredient amounts needed for 12 people, showing their work using ratios or multiplication. Then, provide a medication dosage for an adult and ask them to calculate the correct dosage for a child who weighs half as much, using decimals.

Activity 02
Pairs: Game Designer Geometry Map
Pairs use grid paper to design a video game level with shapes, angles, and paths for character movement. Label geometric properties and justify choices for smooth navigation. Share designs with the class for feedback.
Justify why geometry is critical for a video game designer or an animator.
Facilitation TipIn Pairs: Game Designer Geometry Map, provide grid paper and rulers to support accurate measurement and transformation tasks.
What to look forPose the question: 'Imagine you are designing a new park. What mathematical concepts from geometry would you need to consider to plan the layout of paths, playgrounds, and seating areas?' Facilitate a class discussion where students share their ideas and justify their choices.

Activity 03
Whole Class: Nurse Measurement Clinic
Set up stations with mock patients. Students measure 'dosages' using decimals on syringes, record vital signs, and calculate totals. Rotate roles and compile class data to identify patterns in patient care.
Analyze the ways nurses use measurement and decimals to ensure patient safety.
Facilitation TipFor Whole Class: Nurse Measurement Clinic, set up four stations with measuring tools and dosage charts to ensure all students engage with decimal calculations.
What to look forAsk students to write down one profession discussed and explain how either fractions/ratios, decimals/measurement, or geometry is essential for a specific task within that profession. They should provide a brief example.

Activity 04
Individual: Profession Math Reflection
Students choose a profession, list 3 Year 5 math skills used, and create a poster with examples like time scheduling or money budgeting. Share one insight in a class gallery walk.
Explain how a chef uses fractions and ratios to scale a recipe for 100 people.

Generate Complete Lesson→A few notes on teaching this unit
Begin with a brief whole-class example that connects math to a familiar profession, then move to guided practice. Teachers should model precision in language and calculation, especially around decimals and fractions, to prevent common errors. Avoid rushing through explanations—pause after modeling to allow students to articulate their thinking before moving to independent work.
Successful learning looks like students actively applying mathematical concepts to solve realistic problems, explaining their reasoning clearly, and connecting skills to meaningful career tasks. Evidence includes accurate calculations, thoughtful design choices, and reflective discussions.
Watch Out for These Misconceptions
During Role-Play: Chef Recipe Scale-Up, watch for students who treat fractions as whole numbers or skip the ratio step entirely.
Prompt students to verbalize their scaling steps aloud, such as ‘If 2 cups serve 4 people, how many cups serve 12?’ Use peer feedback to correct errors in real time.
During Pairs: Game Designer Geometry Map, watch for students who draw shapes without considering angles or proportions.
Ask pairs to justify each shape’s dimensions using geometric properties, such as ‘Why is this triangle equilateral?’ and have them test their design with a classmate.
During Whole Class: Nurse Measurement Clinic, watch for students who round decimals prematurely or ignore units of measurement.
Use measuring tools with clear markings and require students to record doses to two decimal places, then discuss the impact of rounding in medical contexts.
