Pupils who are secure will be able to:

• Identify stronger and weaker supporting shapes.
• Recognise that supporting shapes can help increase the strength of a bridge so it can hold more weight.
• Identify beam, arch and truss bridges and describe their differences.
• Use triangles to create simple truss bridges that support a load (weight).
• Cut beams to the correct size using a cutting mat.
• Smooth down rough cut edges with sandpaper.
• Follow each stage of the truss bridge creation as instructed by the teacher.
• Complete a bridge with varying ranges of accuracy and finish supported by the teacher.
• Identify some areas for improvement and reinforcing bridges as necessary.
