Each of the problem situations in this series are designed to help the busy teacher structure an effective and informative problem solving lesson. They each include:

• Links to the Australian Curriculum Mathematics
• A lesson plan based on the STAR problem solving model
• Scaffolding questions and prompts to use with students
• Hints about what to look for and notice as students work on the problem
• Typical student work samples that show the expected range within any classroom
• Reflection suggestions
• Thoughts about follow-up

Differentiation and formative assessment is built into each lesson.
