Pupils needing extra support: Provide extra help by doing the making stages one at a time and reviewing with the children before moving on, this can break up the activity and also make it feel more manageable. Allow the children to work in pairs or small groups as a production line and switch stations. Use verbal and visual prompts, such as photographs and video clips taken through lesson 3 – 4 to support the final evaluation.

Pupils working at greater depth: Express the need to achieve a high-quality finish, sanded down, accurate with no gaps and secured at all joints effectively. Employ them as ‘Construction assistants’ to support the rest of the class or an assigned pupil if they finish their truss bridge ahead of schedule and can do no more to improve its strength. Explain in detail the status of their finished truss bridge with regards to the quality of finish, accuracy of the joints and overall build referring back to skills and tools used. Discuss what they would change if they were to do the truss bridge project again.
