🎯 Learning Intentions

• I can apply addition strategies to real-life scenarios and word problems.
• I can create meaningful, clear, and mathematically accurate word problems.
• I can collaborate to develop and present a problem-solving challenge for peers.
• I can justify my mathematical thinking when solving problems.

---

✅ Success Criteria

By the end of the lesson, students will:

• Accurately solve addition word problems
• Be able to explain their chosen strategy
• Work collaboratively to design, present and reflect upon real-life problems
• Use correct spelling and clear, legible handwriting (focus on cursive where possible)

---

🧠 Prior Knowledge

Students should already:

• Be familiar with mental and written addition strategies (from Lessons 1–8)
• Understand place value and the use of decimals (especially Years 6+)
• Be developing their own methods of estimating and checking their answers
• Know how to break down a word problem to find key information

---

🧰 Materials

• Whiteboard and markers
• Workbooks and pens
• Visual scenario prompt cards (Australian-themed)
• Word Problem Planning Sheet (provided in class or printed from Google Classroom)
• iPads or laptops (optional for Google Slides presentation)
• Timer
• Decorative manipulatives—e.g. Aussie currency notes & coins, train timetables, supermarket flyers, etc.

🕘 Lesson Breakdown (60 mins)

⏱️ Warm-Up – Mental Maths Challenge (10 mins)

• Activity: Rapid-Fire Addition
  Teacher calls out a set of real-life themed addition questions aloud. Students compete quietly on paper to solve them within a limited time. Example:

  “If your family spends $364.50 on groceries and another $275.90 on school supplies, what’s the total?”
  “A train travels 248 km in the morning and 532 km in the afternoon. What's the total distance?”

• Spelling Focus: Students exchange their papers to peer-check and focus on spelling of mathematical terms: 'distance', 'total', 'estimate', 'difference'.

---

🧊 Hook – Scenario Exploration (5 mins)

Display three engaging and relatable Aussie-themed visual prompts (projector or printed):

1. A day at Luna Park – ticket prices, rides, meals
2. A bush camping trip – gear hire, petrol costs, supply lists
3. A school fundraiser – sausage sizzle, raffle ticket sales, donation box totals

Ask students:

“Can we use maths to solve or organise these situations? How?”
Stimulate discussion using "Think-Pair-Share".

---

🤲 Group Task – Create Word Problems (25 mins)

Step-by-Step Instructions:

1. Divide class into pairs or small groups of 2-3.
2. Each group selects or is assigned a visual prompt or creates their own real-life context.
3. Using the Word Problem Planning Sheet, groups will:
   • Identify the storyline & setting
   • Choose at least two addition-based questions (can use decimals, large numbers, or mixed values)
   • Work out solutions using at least 2 strategies
   • Draft neatly using cursive handwriting on A3 poster or digitally in Google Slides
   • Check spelling and grammar

Teacher Role:

• Move between groups, prompting depth by asking:

  “What maths is hidden here?”
  “How did you decide what numbers to use?”
  “Can others solve this? Is it fair/challenging?”

---

🎤 Presentations & Peer Responses (15 mins)

Groups present their word problems to the class (or display posters). Other students attempt to solve the problem collaboratively, explaining their working aloud.

Encourage peer feedback:

• “What made this a good challenge?”
• “What helped us understand the question?”

👉 Display successful strategies and high-quality cursive samples on a shared class display or digital noticeboard.

---

✒️ Reflection and Bookwork (5 mins)

Students write a short paragraph in their workbook, responding to one or more of the following prompts:

• “Today I used addition to…”
• “Next time, I want to try using…”
• “I found it helpful when…”

End with a quick whole-class thumbs-up/thumbs-down/posture check to gauge understanding.

---

📈 Assessment Opportunities

• Observation of group collaboration and problem-solving discussions
• Assessment of final word problem quality
• Accuracy and clarity in workbook reflections
• Spelling accuracy and handwriting legibility
• Student question and answer responses during peer presentations

---

🌟 Extension for Advanced Learners

• Incorporate Rates & Ratios: Extend word problems to include unit pricing (e.g., cost per item), or time-based rates (e.g., cost per hour).
• Add a Budget Constraint: Students must devise a scenario and stay within a particular amount (e.g., organising a class celebration with a $200 limit).
• Design & Host a ‘Maths Café’ Challenge: Students take roles: server, cashier, customer. Use real Aussie menus and prices, students must calculate bills, change, and suggest combo deals.
• Video Presentation: Record their scenario and solution as a video explanation to submit via Google Classroom.

---

🧩 Homework / Home Learning Task

• Solve three addition-based word problems from their workbook (teacher provided or created by peers in class)
• Create one original written word problem using a real scenario from home (e.g., cooking, budgeting, shopping, or sports stats), written neatly in cursive with accurate spelling.

Upload solutions to Google Classroom or attach to weekly workbook entries.
