Securing Pipes intro: pair-work rules and a diagram of a strap around 3 pipes as 6 radii plus a circumference
Hand out first to set up pairs, timing, equipment and peer review
Strap length patterns: students compare 3 ways to stack 3 pipes, then find a rule for strapping triangular stacks
Tasks 1 and 2: reasoning about stability, then generalizing a rule
Real-world variation: students find the strap length in terms of r for 5 pipes stacked as in a roadside photo
Task 3: applying the pattern to a real photographed stack
Non-triangular pipe counts: students investigate strap length for 4 pipes, then for 7 and beyond
Task 4: open-ended investigation to close the assessment
