3D structures, Angles, Transient Art and lots of great conversation, whilst making Hot Chocolate and Smores (toasted marshmallows between biscuits)
This activity is good for upper primary. Ask each pupil to pace out 20 metres along a path then mark the spot (ideally with their own crossed marker lashed together that they have made earlier.) Then, as a group, use a tape to measure the distance to find who has estimated most accurately. Repeat with different distances. Children enjoy the challenge of this!
Younger children can be challenged to measure big steps and small steps, or moving in different ways – hopping and striding. They can explore the ideas of scale and units of measurement. For example – how many oak leaves in a line can stretch 50 cm compared to say, willow?
