WHAT

- Maths facts are only a small part of mathematics

- Mental computation is not about having fast, but efficient strategies to work out number problems.

- 6 x 7 = 42. If you know this by rote, you don't necessarily have number sense. You also need to understand how this might look as an array which will help you to know halves, doubles and other ways that this equation can be represented. 

- Flash cards and speed maths games do nothing but prove who is the fastest, not necessarily who has the best understanding.

SO WHAT/NOW WHAT
For the most part I agree with this article. It is important for students to be able to have number sense so that they can apply their existing knowledge flexibly across a range of scenarios and contexts.

I think that this article underplays how having quick and efficient recall of basic facts can open up opportunities for students to solve more complex problems. For example, It is very difficult to solve 126 divided by 6, without instantly knowing that 6 x 20 = 120. I believe helping students to acquire a range of basic facts that they have quick access to will help them to move forward as mathematicians. I believe the key is to push students to use these skills creatively and flexibly to a range of contexts and scenarios.
