Answer keys and mini folded notes are also included.

Skill Level: Easy
Grades: 6th to 9th

Key Learnings:

• Demonstrate that the trapezium area is the average length of its parallel sides multiplied by the perpendicular height. A = h/2(a + b)
• Use the trapezium formula to calculate trapezium areas and convert between area units
• Apply strategies, reasoning, and explain mathematical relationships using other two-dimensional shapes to find the trapezium area

Australian Curriculum:

• Recognise and explain mathematical relationships using reasoning (MA4-3WM).
• Apply appropriate mathematical techniques to solve problems (MA4-2WM)
• Communicate and connect mathematical ideas using appropriate terminology, diagrams and symbols (MA4-1WM)
• Establish the formulas for areas of rectangles, triangles and parallelograms and use these in problem solving (ACMMG159)
• Find areas of trapeziums, rhombuses and kites (ACMMG196)
