I have been a teacher for over 20 years - all the stuff I upload has been tried and tested in my classroom. I don't mind a discussion on Twitter too where I also share new resources. I now have a personal website: https://andylutwyche.com/

I Need A Loan!

I Need A Loan!

(2)
This leads on from 'Misleading Graphs' where the students have to draw a graph in an effort to convince a Small Business Manager to give them a loan.
Function Machines Puzzles

Function Machines Puzzles

(3)
Can you calculate what the workers in each box are doing on the mathematical building site? It's essentially function machines but where you have the answers but need to find the rules.
Differentiating Explosions

Differentiating Explosions

(0)
Three slides with different differentiation problems. The first asks students to differentiate, find a gradient and equation of a tangent at the given point; the second asks the same but the equation of the normal at the given point; the third asks students to find the turning/stationary points. I have thrown in a bit of integration (by stealth) as well just as a challenge… and this could be used for IGCSE or A/AS Level.
A Natural Sequence
alutwychealutwyche

A Natural Sequence

(3)
This is designed to add some "real life" and to enhance to a sequences lesson. It links into the golden ratio and has a link to a YouTube video on the subject. There are invitations to calculate the golden ratio and to draw the Fibonacci spiral.
Function Notation Matching

Function Notation Matching

(5)
Eight matching activities that encourage discussion in class involving substituting into functions, inverses and composite functions. These would work as a starter/plenary or as a revision lesson on function notation.
Quadratics Matching
alutwychealutwyche

Quadratics Matching

(0)
This takes students through factorising quadratics, solving them and onto completing the square, including solving quadratics that won't factorise nicely. Designed as starters/plenaries/assess the learning activities.
Building Blocks - Statistical Diagrams
alutwychealutwyche

Building Blocks - Statistical Diagrams

(2)
Taking students all the way from pictograms, through bar charts, pie charts, stem-and-leaf, scatter graphs, frequency diagrams, cumulative frequency, box plots and histograms. The graphs are as large as I can make them and should be ok if copied on to A4.
Non-Examples - Coordinates and Graphs - Reasoning Tasks
alutwychealutwyche

Non-Examples - Coordinates and Graphs - Reasoning Tasks

(3)
Six slides each containing five questions where students need to decide if the answer given is correct and explain how they have arrived at their conclusion. Topics include whether a coordinate lies on a line given its equation, y=mx+c, equations of curves (quadratics, cubics, reciprocals), gradient, These are designed to generate discussion in class.
Transformation Options
alutwychealutwyche

Transformation Options

(0)
There are twelve transformations here, all of which have more than one solution; this asks students to find as many solutions that work, including reflections, translations, rotations and enlargements with negative scale factors. I did this with a class and offered rewards for any solutions I hadn’t listed which seemed to motivate them even more! Solutions are on a separate slide to enable printing.
Non-Examples - Function Notation
alutwychealutwyche

Non-Examples - Function Notation

(0)
Each slide contains five questions that have been answered, but not necessarily correctly. Your class need to discuss whether the answer given is correct or not and find the correct answer if not. These bring up common errors and lots of discussions. Areas covered: substitution, inverses, composite, domain & range.
Deriving The Addition Formulae
alutwychealutwyche

Deriving The Addition Formulae

(0)
I got shown this by a colleague so thought I would PowerPoint it; there are essentially a few versions of the same thing: Minimally labelled etc - for a strong set of mathematicians All angles marked The side or angle you need to find next is highlighted I will use this to introduce the addition formulae. There may well be other/better versions out there so I am sorry if I have wasted your time.
Ratio Spider
alutwychealutwyche

Ratio Spider

(5)
This covers sharing in a given ratio, simplifying and recipes. Each spider has challenges for discussion when seeking solutions. Designed to encourage discussion.
The Best Deal
alutwychealutwyche

The Best Deal

(2)
This is an exercise in finding the best way of buying what a customer wants given four different “deals” on pricing. You can buy more than required but not less which should add an extra bit of challenge. Workings are essential and I have provided answers on a separate slide each time. There are five to work out and this should lead to nice mathematical discussions. I have also put this in a format that could be used easily online if this is desirable.
Surface Area and Volume Spiders
alutwychealutwyche

Surface Area and Volume Spiders

(6)
Six spiders on surface area and volume (3 of each) and a final "problems" spider. They are of increasing difficulty, moving from cubes and cuboids to prisms to cones, spheres and pyramids. These are designed to avoid students getting into a rut of performing a mathematical recipe by asking a mixture of finding surface area/volume to working backwards. These usually encourage discussion in class.
