Adaptive teaching
Pupils needing extra support
Could verbally explain how wheels work and objects move when researching the selection of wheeled items rather than writing; could use something circular to draw around when designing their own fairground wheel; could refer to the Knowledge organiser when designing their own fairground wheel; could use the Activity: Wheel design: support version when designing their own fairground wheel; should be encouraged to cater for eight people so they only need four pods (two people in each), which are easier to space out by splitting the wheel into quarters.
Pupils working at greater depth
Should be encouraged to refer to the design of wheels, axles and axle holders when justifying, offering alternatives or finding solutions; should justify their choices for each aspect of their design, including materials and shapes.
