Activity: to recognise, visualise and name 3-dimensional figures [lo 3.1.1]
To investigate and compare 3-dimensional figures [lo 3.3.1]
1. The following nets are examples of pyramids.
Trace them exactly, cut them out and fold each pyramid.
2. Hold a class discussion and draw up a list of the similarities and differences that you notice between the two pyramids.
Assessment
Learning Outcome 3: The learner will be able to describe and represent characteristics and relationships between two-dimensional shapes and three-dimensional objects in a variety of orientations and positions.
Assessment Standard 3.1: We know this when the learner recognises, visualises and names two-dimensional shapes and three-dimensional objects in natural and cultural forms and geometric settings, including those previously dealt with and focusing on:
3.1.1: similarities and differences between tetrahedrons and other pyramids.
Assessment Standard 3.3: We know this when the learner investigates and compares (alone or as a member of a group or team) two-dimensional shapes and three-dimensional objects studied in this grade according to properties listed above by:
3.3.1: making three-dimensional models using:
- drinking straws to make a skeleton,
- nets provided by the teacher;
