Perimeter, Area and Volume - Area of a Triangle (2) - Worksheet

This worksheet from masterthecurriculum.co.uk is designed to teach Year 6 students about the area of right-angled triangles through fluency, precision, reasoning, and problem-solving activities. The National Curriculum objective is to recognise when formulae for area and volume can be applied and to calculate the area of parallelograms and triangles. Key vocabulary such as 'approximate', 'area', 'triangle', 'square', 'length', 'perpendicular', and 'formula' are used throughout the lesson. Students will use their understanding of finding the area of a rectangle to then find the area of a right-angled triangle, learning that the latter is half the area of the rectangle when they share the same length and perpendicular height.

The worksheet includes differentiated sheets and teaching slides to cater to varying abilities, ensuring that all students can engage with the material effectively. Key questions prompt students to compare rectangles and triangles, explore their relationship, and deduce the formula for calculating the area of a right-angled triangle. For example, they are asked to consider what is the same or different about a rectangle and a triangle and to use the formula for the area of a rectangle (length x height) to determine the area of a triangle. This educational resource is geared towards helping students to understand and apply mathematical concepts to find areas of triangles, parallelograms, and composite shapes, enhancing their geometric understanding.
