Which one doesn't belong is a great prompting discussion within maths time. I use these a few times a week to get students to think about the possibilities and talk about their own reasoning with a buddy. These can be used within any year level, in whole class discussion, group discussion or individually!
I attended a PLD session from Donna Golightly who shared the website to these fantastic thinking prompts! I downloaded and collated some into some slideshows for you to use as well in your class!
There are two sections:
Which one doesn't belong - shapes
Which one doesn't belong - number
Click on the links above to access the google slide deck with some prompts you can use in your maths time. It is a great way to talk about different maths prompts, strategies and ways students think or interpret information. This helps students realise how huge the concept of maths can be and that their way of thinking isn't always the only way!
