What’s the Radius?

Description

This resource is aimed at middle/senior class pupils or SEN pupils at the beginning of work on learning about the Circle and its properties. It features images of circles in pastel shades with the diameter marked in cm on each one. Each card asks the question “What’s the Radius?” The pupil has to use their knowledge of the properties of the Circle, knowing that the radius is half the diameter, to work out the length of the radius.

There are four cards per A4 page. Cut up the sheets into 19 separate cards and laminate them individually. The pupil should look at the image of the Circle on the left side of each card, noting the length of the diameter. They then work out what the length of the radius is and place a clothes peg on the correct answer on the right of the card, from the three possible answers given. 

This activity is especially suitable for pupils who may not be able to write answers but know their shapes. It is a way for them to demonstrate their understanding of the properties of the Circle. It is also good for fine motor skills in the manipulation of the pegs onto the cards.

This activity would also work well as a station activity during maths Station Teaching, where a pack is made up for each pupil in the group.

We frequently gave activities such as this for homework to our SEN pupils. It gave them the sense that they had homework like everyone else and it also allowed the parents to see what maths topic we were currently working on.

This activity could also be completed by the pupil as an independent task in their work station.
