Tricks and Tips 1: HCF. I recently presented a workshop at the National Mathematics Teacher Conference (#mathsconf2015) entitled 'Tricks and Tips: Clever Methods for Explaining Mathematical Concepts'. This post summarises the content of that workshop for those who were unable to attend. I have quite a lot to cover so I expect I'll need to write three or four blog posts. In this one I'm going to explain the rationale for the workshop and describe alternative methods for finding a Highest Common Factor. In subsequent posts I'll cover sequences, linear graphs, surds, quadratics, compound measures and a few more bits and pieces. Workshop aim How do you find the Highest Common Factor of two numbers? What determines the way we choose the explain things? Most teachers establish teaching habits during their training and NQT year. One of the few things I remember about GCSE maths was that I solved equations by 'moving terms over the equals sign' (the 'magic portal method'). 1.

What do a teacher and entrepreneur have in common? “Those who can, do, and those who can’t, teach” The old adage above couldn’t be further from the truth in my opinion.

I like to say “those who can, have unrelenting energy, buckets full of passion, an ability to be masterful communicators and work in sometimes tough conditions, teach” And so begins my thinking that there may be much more in common in the art of teaching and entrepreneurship than may meet the eye. Here are but a few of the traits I believe successful teachers and entrepreneurs share: The art of selling: What’s the situation at the front of a class? A great teacher has the passion, character and ability to do this – to interest those pupils and inspire them into their subject and world.

Management and team building: A great teacher effectively has a team of 30 people in front of them. Understanding and empathy: A great teacher knows their students so well – this doesn’t mean they know every single intimidate detail about their lives.

Notoriously difficult for pupils to understand, I think addition and subtraction of negatives is one of the things that one comes to understand after doing lots of practice.

HOWEVER, that practice needs to be yielding correct answers from the off. It’s no good sending pupils off to do lots of practice if they’re getting it wrong as often as they’re getting it right. Heavily influenced by our reading on working memory, here’s how we teach addition and subtraction of negative numbers: When to start – We start teaching negative numbers at the beginning of year 8.

Introducing – We spend the first lesson introducing negative numbers – touching on their history, real-life applications (briefly), finding them on a number line, ordering them, etc. No analogies – When teaching addition and subtraction, we NEVER talk about “two negatives make a positive” or use analogies about ice cubes, good/bad people, or use negative/positive tiles.

Adding and subtracting positive numbers with a positive answer. Tricks and Tips 1: HCF. Factorising Harder Quadratics. My pupils panic at the sight of a quadratic with a leading coefficient greater than one. I factorise these quadratics by inspection (the 'guess and test' method) but my pupils aren't satisfied with this suggestion - they want a more structured approach. A commonly taught method in the UK involves splitting the middle term in two (sometimes called the 'Grouping Method'). This is explained very clearly here (thanks to SRWhitehouse for this resource). Teachitmaths.co.uk has a PowerPoint explaining this method. It's worth watching James Tanton's video 'Splitting the Middle Term' too. He's not a fan! An alternative, which seems easy at first but paves the way for a large number of misconceptions, is the 'slide and divide' method.

Nix the Tricks offers an interesting alternative - I've provided two examples here but it's worth reading the book for the full explanation. How to help every child understand ratio. Dividing a quantity unevenly is an abstract idea that most children struggle with. As the problems become more complex, people struggle all the more to see what to do, for example: Jack and Jill share £28 in the ratio 5:2, how much does Jack receive? Jack and Jill share some money in the ratio 5:2. Jack receives £15, how much does Jill receive? Even a child who successfully gets their head around the process of ‘adding the numbers, divide by that amount, multiply by each number separately,’ for question 1, is then straight away often stumped by what to do when faced with question 2. There are two effective techniques for making ratio problems concrete that somehow seem to slip people for a long time, and those who know about them seem to come across by chance.

The Box Method Draw out boxes to represent the ratio. It quickly makes much more sense to a person now that they will need to share out the £28 from question 1 into 7 boxes. This method copes equally well with question 2. Before: Times Table Rockstars - Page Site. Online Version Benefits: As a teacher myself, I know that pupil engagement, learning, time and budget are important. In the development of TT Rock Stars I've given all these aspects careful consideration. Maths teachers recognise how fundamental times table recall speed is to later success in maths lessons; yet it's not always easy finding engaging ways to do daily practice. TT Rock Stars (the paper version) has been used in many schools across the UK since 2010 and the feedback is that pupils and teachers love it.

Features: As the teacher, you can select which times tables they practice each week. Want to know more? Before or after signing up, if you want to ask anything about TT Rock Stars or if something isn't working the way you think it should then email me (bruno@mrreddy.com) or call me (07800 888 800). Paper Version I'm glad you liked the look of TT Rock Stars. First, watch this video, which will give you a good idea of what TT Rock Stars is and what it can do for your pupils. Maths everywhere. I don’t have much truck with “numeracy across the curriculum”. Dani Quinn has explained why better than I could here. But here’s something I think is much more powerful: a culture of valuing maths across the school. A sense in which it’s not just Miss Isaksen who cares about maths, but every teacher.
