Core Maths in Pictures

This simple resource consists of a series of pictures that can be used as a starting point to generate Fermi estimation questions. Some notes and suggested approaches are provided, and the activity can easily be extended using other suitable pictures.

Overview of task

This simple resource consists of a series of pictures that can be used as a starting point to generate Fermi estimation questions. Some notes and suggested approaches are provided, and the activity can easily be extended using other suitable pictures.

Prior knowledge

Students will need to understand the process of Fermi estimation. Alternatively, this resource could be used to help introduce this topic.

Relevance to Core Maths qualifications

•AQA

•C&G

•Eduqas

Suggested approaches

Learners could work in groups of two or three to create a Fermi estimation type question based on the current picture. The groups could then share their questions with the whole class for them to work on. This resource could be used as an introduction to Fermi estimation or as a follow-on to work on Fermi estimation.

Resources/documentation

The supplied presentation introduces the task and further suggestions about possible approaches are supplied in the presenter notes.

+
Relevant digital technologies

Interactive whiteboard technologies (or digital cameras) could be used to record students’ work. Internet access might be useful if students need to research particular data points, such as the world or UK population.

+
Possible extensions

The essence of this activity lies in its simplicity – we simply present a picture and invite students to respond to the question ‘What could you ask?’ This makes it an ideal activity for students to take on and extend for themselves; they could take it in turns to bring suitable images to class to be used as stimulus material for a Fermi estimation lesson starter.
