This blog post, the next in the ‘promoting reasoning’ series, features question types that help children to build on their current knowledge and notice important similarities and differences between questions.
I’m always looking for ways to promote non-counting calculation (there are overlaps here with my ‘visuals’ blog). Prompts like the below-left example helps children to make connections between doubles and near-doubles facts. Children can edit the image to help them see those relationships. Similarly, I love using ‘I know… so…’ question strings. In the below-right example, I hope children will either perform the calculation using the related fact, or they will see the relationship between the three questions.
The examples below probably fit the criteria of ‘variation’ more tightly. Specifically, by keeping all but one aspect of a question/image the same, children’s attention is drawn to the key difference. Consider the below-right example: the left hand image the dominant idea is likely to be ‘one circle’; the right hand image emphasises ‘four quarters’ more. Used together, children’s attention is drawn to four quarters being the same as one whole.
When using the ‘I know… so…’ prompt, I might adjust the amount of variation between the examples depending on where children are up to in their learning. That’s all about knowing your children, the magic ingredient that every great teacher has up their sleeve!
