The 2D Shape Drawing Debugging has been rated 5 stars

RESOURCE OVERVIEW:

In this activity pupils will follow an algorithm to draw pictures constructed from 2D shapes. The algorithms they follow will include errors and pupils will use logical reasoning to detect and correct these.

PUPIL OBJECTIVES:

I can use logical reasoning to detect and correct errors in an algorithm.

TEACHING ASSESSMENT OPPORTUNITIES:

Informal, teacher assessment of progress during main task, class discussions and plenary. Focus on how pupils use logical reasoning to identify errors in an algorithm and fix errors in the algorithm.
Formal, summative assessment of debugging sheets if required.
