TES Maths Resource of the Week

Resource title: Odd-one-out activities

Resource author: danielwkelly

What is it?

This versatile collection is a complete gift. Not only do each of the 24 worksheets cover a wide range of topics, but they also follow the same format. This means that less time is spent explaining the activity, leaving more to consolidate learning. 

Engaging, challenging and easy-to-mark, these tasks come with nine answers but only eight questions. Students work through each of the problems to identify the one remaining answer.

How can it be used?

Covering topics such as brackets, fractions, factors, equations, sequences and indices, the author suggests that these activities make good starters and plenaries.

While that is undoubtedly true, I feel they also have the potential to make up the main body of a lesson, not least because they have an in-built source of richness in the form of the odd answer. Don't just leave it sat there doing nothing! Why not get students to create their own question for it?
