Preempt mathematical misconceptions by avoiding short-term shortcuts and by using vocabulary that helps children stay on track. Recognise when misconceptions are underlying systematic errors. Hamilton's misconceptions documents will help you teach for understanding now and later too.
These aren’t simple arithmetical errors, but important common misconceptions that need unpicking. If you’ve been teaching these year groups for a while, you may already recognise these misconceptions, but what if you are new to a year group or new to teaching? And, to be honest, we can all use a reminder of the many ways that understanding can be derailed.
To help, Hamilton's maths blocks have a common misconceptions document for each unit, so you can look out for what might go wrong. If you are aware of these, you can adapt your teaching to try and preempt them.
We have also included a ‘Resist the temptation to…’ section. Let’s be honest, we’ve all said something in our teaching and then regretted it! ‘When you multiply by 10, you add a zero’. Oops, the children add a zero when multiplying decimals (10 x 4.5 = 4.50). How many of us have used the word ‘borrow’ when teaching column subtraction? A child with a heightened sense of justice asks, ‘When will we give it back?’ Perhaps not a helpful word to use here! (The word ‘borrow’ dates back to an old method of subtraction, but that’s another story.)
You will also see a section of key words and phrases that are useful for the unit, and a few key questions to tease out if the children have got the key understanding and skills being taught.
