This is a complete lesson on geometrically proving and then applying the addition formulae. The lesson consists of 30 slides which guide students through a step-by-step proof of sin(A+B) and cos(A+B), then how to prove tan(A+B) and all the subtraction versions from these, plus a further six slides covering three common questions on the application of the formulae (which can be used as examples or as questions). It also includes copies for the students to complete as you go along.
Resources included:
A PPT and smart notebook file 36 slides long with a detailed step-by-step proof using SOHCAHTOA.
A student copy of the initial diagrams for them to work from
There is a separate file for PPT and notebook.

This is a ready to teach lesson on how to implement the Simplex Algorithm in 3D, showing first how it could be done graphically if we had the right software, then applying the Simplex Algorithm to the same problem.
The lesson is 27 slides long, with tableaux for the students to work through at the same time.
The lesson is provided in Notebook and PDF format.
I will soon be uploading the next lesson for Simplex Algorithm so watch this space.

This is a complete lesson on introducing equivalent fractions. It is assumed that students are able to shade and recognise fractions.
Depending on the ability of the class, it can take between 1 and 3 hours.
It makes use of pictorial representations, fraction walls (provided) and develops this into using multiplication to find equivalent fractions.
Resources included:
A smart notebook and PPT file 76 slides long
Two versions of a fraction wall (ideally to be laminated, but an alternative version is provided if this is not possible)
3 activities for the fraction walls
1 activity in which students walk up to the board to find equivalent fractions
1 cut out and match up activity
Resources required;
Mini-Whiteboards
Scissors (and glue if you want the students to stick the matching activity down)
Laminator (optional)
Powerpoint or Smart Notebook

This includes the first two lessons on the Simplex Algorithm:
How to implement the Simplex Method and why it works, referring back to graphical and algebraic approaches. It is unclear to many students why the Simplex Algorithm works, what theta values are and why you need to look for the most negative value in the last row. The primary objective of this lesson is to thoroughly explain all of this.
How to implement the Simplex Method in 3D, showing first how it could be done graphically if we had the right software, then applying the Simplex Algorithm to the same problem.
A lesson on reverse percentages, including a lesson with detailed slides, two worksheets and other activities (which can be done on mini-whiteboards).
Objectives are:
Get students to recognise when a question is a reverse percentage and when they are normal percentage questions
Students to be able to answer reverse percentage increase and decrease questions
This is a bundle containing three GCSE progression grids (from Grade 1 to Grade 9) on Area and Volume:
Areas of Circles and Sectors
Volume of Cones, Pyramids and Frustums
Transformations
Venn Diagrams
The grade 1 question is worth 1 mark, the grade 2 is worth 2 and so on. I facilitate marking by saying it’s all-or-nothing, but that’s up to you.
The grids can be:
Used in lesson for students to see what grade they can get to
Peer/Self/Teacher-assessed
Used independently
Done for Homework
Laminated and given as revision cards.
The answers, with full working out are included.
If you have any suggestions or have spotted a mistake, do not hesitate to contact me via lastminutemathslessons@gmail.com.
I’m in the process of uploading other grade grids - please let me know if you have any specific requests.
Thanks!

This starts with a reminder of differentiation and how it works (which can be skipped if you prefer), then goes into detail about differentiation from first principles, using chords on a curve. It can pretty much be picked up and taught without much preparation, as long as the teacher has an understanding of differentiation and how to find the gradient between two points.
Full Sequence of lessons in one notebook file for polar coordinates including:
Converting between polar and cartesian form
Plotting polar equations
Integration
Differentiaion,
Total number of slides = 77
This bundle contains 5 lessons:
Floyd’s Algorithm
Graph Theory and the Planarity Algorithm
How to find the order of an algorithm
Explaining how the Simplex Algorithm works
Applying the Simplex Algorithm in 3 dimensions
