Fifty Shades of Grey Addition

Charlie Harber is Deputy Lead Adviser for Primary Mathematics at Herts for Learning.  This blog aims to take the seemingly simple operation of addition and demonstrate how we can vary presentation in order that pupils see connections and do not fall into shallow procedural thinking.

Would you agree that these are all shades of grey? (Who hasn’t spent time deliberating between shades on a paint chart?)  They are all different. So how can they be all grey?

We are generalising what is meant by GREY. Oxford online dictionary define grey as ‘Of a colour intermediate between black and white’ – so under this definition all these colours, despite being different, are grey because they share this similar property. For children to understand what grey is, what would you do? Would you just present them with a single shade? More likely, one activity you would do is present them with a range of objects in lots of different colours including shades of grey and ask them to sort the objects based on their colours. In mathematics we could refer to this as part of generalisation – the ability to see what is common amongst a range of different situations. Continue reading “Fifty Shades of Grey Addition”

Bar Modelling is a Leap of Faith

Charlie Harber is the Deputy Lead Adviser for Primary Mathematics at Herts for Learning.  A passionate advocate of bar modelling, her last blog on the subject RUCSAC pack your bags, dealt with a KS2 SATs question.  Here Charlie turns her attention to KS1 bar modelling.

In my last blog on bar modelling I used an example from the 2016 KS2 test. Subsequently, I had had a number of requests asking for a similarly worked example of a KS1 test question.

So you have textbooks…so what?

Siobhan King is a Mathematics Adviser at Herts for Learning

I have been thinking about maths text books: what they add to lessons and how they can be used effectively.  I am a firm believer in not reinventing the wheel and know that teacher time is finite and exceptionally valuable.   Furthermore, I agree with Tim Oates’ assertion that “high quality textbooks support both teachers and pupils – they free teachers up to concentrate on refining pedagogy and developing engaging, effective learning.”  (Oates, 2014, p4) Continue reading “So you have textbooks…so what?”

Is mastery just a passing fad?

 

Nicola Randall, Mathematics Teaching and Learning Adviser at Herts for Learning

Before I even start to tackle this question, I think it is helpful to clarify what we mean by ‘fad’ and the best way I could think of doing this was to consider some examples.

  • Leg warmers worn anywhere other than inside a dance studio: fad
  • No make-up selfies: fad
  • Replacing actual laughing with the word “LOL”: fad
  • Dressing as clowns and scaring people: fad

Why dodecahedrons hate CPA.

Rachel Rayner is a Primary Mathematics Adviser for Herts for Learning

For a blog about the CPA approach click here.

Yes, teachers do label their fixed ability groups by shapes…still. Yes, pupils do end up in the circles group from the age of five and in some cases in the teacher’s head, younger.  And yes, it damages.  We are all by now familiar with the work of Carol Dweck and the idea of fixed and growth mindsets.  But in maths at least this fixed ability grouping or setting persists in Primary, despite the evidence that it can be detrimental to those pupils designated ‘circles’ or ‘triangles’.   Continue reading “Why dodecahedrons hate CPA.”

Take One Resource: The Counting Stick

Deborah Mulroney is a Primary Mathematics Adviser for Herts for Learning

In this blog the resource that we are focusing on is the counting stick. It usually has ten intervals but the type with four faces and divided in several ways are most useful. The main use is that it can be thought of as representing a three-dimensional empty number line.

Numberline 1

CPA: using Cuisenaire to support pupils to develop fractional understanding

Louisa Ingram is a primary mathematics adviser for HfL

Identifying Fractions

To begin with, pupils need to become familiar with assigning a value to a rod and finding the fractional value of the other rods. A good starting point is to find the value of the white rod as this then allows you to find the value of all other rods. When the brown rod equals 1; the white rod is one eighth. Compared to dark green, the white rod’s value is one sixth. Against blue, it is one ninth and against orange one tenths etc. You can then start to apply this such as assigning the brown rod a value of 2. Through this you can also draw attention to fractions such as which rod is one half, one quarter, one third the length of etc. Continue reading “CPA: using Cuisenaire to support pupils to develop fractional understanding”
