Task: Measuring using different methods in the outdoor classroom

Classroom work pre-visit

Activity: Look at the equipment you will take to the cemetery and discuss how it can be used. Talk about non-standard measures, for example, strides. Discuss the problems involved in taking circumference measurements.

Vocabulary: circumference, girth.

At the cemetery

Activity: Measure and record the circumference of different trees at working heights, with pupils choosing the most appropriate method.
Activity: Measure the distance around the central former chapel area using different units and equipment. Other distances can be measured, eg between trees, or memorials.
Activity: Measure a distance in strides, then re-measure using standard units and compare. Find regular shapes to measure.

Supplementary task: Estimate the height of the trees, do the tallest trees have the biggest circumferences?

Classroom work after the visit

Activity: Arrange the tree circumferences in order of size, compare different results for the same trees and discuss discrepancies. Which was the most accurate way of measuring?

Task: Looking for and making symmetry in the outdoor classroom

Classroom work pre-visit

Activity: Discuss: what does symmetry mean? Ask pupils to find symmetrical shapes/patterns within the classroom. Introduce the line of symmetry and reflection.

Vocabulary: symmetry, line of symmetry, reflection.

At the cemetery

Activity: Collect leaves, sticks, stones and, with Maths partners, build symmetrical patterns. Swap pairs so that pupils can identify the symmetry and pattern in others’ work and continue with the given patterns. Find the line of symmetry in collected leaves.

Supplementary task: Find other symmetrical shapes and patterns in the cemetery and name them.

Classroom work after the visit

Activity: Mount examples of symmetrical shapes found at the cemetery and label them for display. Use mirrors to discover symmetry in everyday objects.

Supplementary task: (KS2) Introduce the concept of rotational symmetry.
