Thinking deeply about what we teach

We are reviewing our year 7 curriculum currently and refining it in preparation for students to come to secondary school a lot weaker than in previous years because of the sheer amount of school time students have missed out on.As part of this I have looked at how we feed forward some of the representations and teaching that we advocate, linking the current topic to future ideas. Talking about why we are promoting using a method or representation and where that then goes on to in their future maths career. 

Not only can this benefit students but it also shows teachers the many ways that we can make links within maths and that something that we may show when teaching place value is also relevant when we look at scales on a graph or explaining why we want to push the use of number partitioning so that when we look at multiplication it can make things easier for us to calculate. These have to be carefuly selected and incorporated though, using a particular representation/method has to serve a purpose. I feel there is no need in doing something if there isnt a particular reason for it and doesn't help me, as a teacher or a student, in the future. 

Below is an example of some of the ideas I had. 

- Number partitioning - to be used to make addition and subtraction calculstions easier. Also used with methods of multiplication.
-Gattegno Charts - can be used to link to standard form and index laws
- Completing Number lines and intervals - can be used with scales on a graph, averages, moves nicely into rounding
- Rounding - links to estimating calculations and checking answers

This is by no means an exhaustive list but as I was writing it it made me realise that a topic like place value can have so much depth to it and we can potentially teach it for weeks if not months exploring lots of concepts around it. When I first started teaching Place Value, it was a 1 or 2 lesson thing that I would get through before I got on to the 'cool', 'tough' maths. But now my eyes are wide open to the endless possibilities and avenues that I could go down with my students. What i will say though is that, we as teachers need to upskill ourselves so that we can better enrich our students with these topics that, when you truly think about it, make such a huge difference to future understanding. 

Place value was a classic that I thought was just for bottom set students and the higher attaining students just needed to answer 1 or 2 questions on it to show me they knew what it was. Thats not mastering a topic though, I've looked at using different number base systems, going into number partitioning, using gattegno charts etc to ensure I am stretching the concept for high attaining students. This continues to be a development for me but one that I am looking forward to adding to my repertoire.

Literacy in Maths

I'm a Maths teacher, I teach numbers. Why is Literacy so important for me? Well….here's why: "Literacy is fundamental for success in school and later life. Students who cannot read, write and communicate effectively are highly unlikely to access the challenging academic curriculum in secondary school and are more likely to have poor educational outcomes across all subjects." (Link 3)  Unfortunately there are a lot of Maths teachers who believe (wrongly) that literacy is a thing that the English department do. They see it as a tick box for observations. Rather than being an essential component of students being able to learn maths.  -  So what does it look like in Maths? Answer the question: Blindle 4x + 6 Are you able to do it?  This is the challenge a lot of students face in Mathematics. Subject specific vocabulary can seem really confusing to a lot of students. Understanding what a keyword is asking of students is often the hardest part of a question and can hold s...

Equivalent Fractions with Ratio Tables

The following is a slide taken from NCETM Checkpoints. I was happy with the fraction pair on the right but the left stumped me! Then I had that 'aha' moment!  What I used to do I never used to teach equivalent fractions like the one on the left to my classes. I would just use arrows to multiply both numerator and denominator to find an equivalent fraction, very similar to the fractions on the right.  The issue with this though is, like me, students don't necessarily see all of the multiplicative relationships between the fractions as well as within the fraction. They are missing that key knowledge to support them answering the first pair of fractions.   What I do now Ratio tables allow students to see those multiplicative links. By doing this it makes questions like the checkpoints task much easier for students to do.  Disclaimer: this isn't the only way I teach equivalent fractions. I also show students how prime factors can also help us. There will be a future...

Percentages with Ratio Tables

What if I said you could teach your students one thing and they could answer everything to do with Percentages? Don't believe me? Let me show you: Finding a percentage of an amount Q: Find 20% of 925 Increasing/Decreasing by a percentage Q: Decrease 45 by 16% Expressing as a percentage Q: A cereal bar weighs 24g. The cereal bar contains 3.6g of protein. Work out what percentage of the cereal bar is protein Percentage Change Q: Rebecca bought a dress for £80.  She later sold it for £116. Find the percentage profit. Reverse Percentages Q: A car increases in value by 35% to £2500. What was its original price? Ratio tables can be used for it all. There is obviously going to need to be some further teaching about what an increase/decrease is, how to work out the multiplier etc, but it is a great tool we should all be using more often You may have worked out by now that I like using Ratio tables.
