A complete lesson on the interior angle sum of a quadrilateral. Requires pupils to know the interior angle sum of a triangle, and also know the angle properties of different quadrilaterals.
Activities included:
Starter:
A few simple questions checking pupils can find missing angles in triangles.
Main:
A nice animation showing a smiley moving around the perimeter of a quadrilateral, turning through the interior angles until it gets back to where it started. It completes a full turn and so demonstrates the rule. This is followed up by instructions for pupils to try the same on a quadrilateral that they draw.

Three example-problem pairs where pupils find missing angles.
Three worksheets, with a progression in difficulty, for pupils to work through. The first has standard ‘find the missing angle’ questions. The second asks pupils to find missing angles, but then identify the quadrilateral according to its angle properties. The third is on a similar theme, but slightly harder (eg having been told a shape is a kite, work out the remaining angles given two of the angles).
A nice extension task, where pupils are given two angles each in three quadrilateral and work out what shapes they could possibly be.

A complete lesson on sharing an amount in a ratio. Assumes pupils have already learned how to use ratio notation and can interpret ratios as fractions - see my other resources for lessons on these topics.
Activities included:
Starter:
A set of questions to recap ratio notation, equivalent ratios, simplifying ratios and interpreting ratios as fractions.
Main:
A quick activity where pupils shade grids in a given ratio( eg shading a 3 x 4 grid in the ratio shaded:unshaded of 1:2). The intention is that they are repeatedly shading the ratio at this stage, rather than directly dividing the 12 squares in the ratio 1:2. By the last question, with an intentionally large grid, hopefully pupils are thinking of a more efficient way to do this…
Examples and quick questions using a bar modelling approach to sharing an amount in a a given ratio.
A set of questions on sharing in a ratio, with a progression in difficulty. Includes the trickier variations of this topic that sometimes appear on exams (eg Jo and Bob share some money in the ratio 1:2, Jo gets £30 more than Bob, how much did they share?)
A nice puzzle where pupils move matchsticks(well, paper images of them) to divide a grid in different ratios.
Plenary:
A final spot-the-mistake question, again on the theme of the trickier variations of this topic that pupils often fail to spot.

A complete lesson on solving equations of the form sinx = a, asinx = b and asinx+b=0 (or with cos or tan) in the range 0 to 360 degrees. Designed to come after pupils have spent time looking at the functions of sine, cosine and tangent, so that they are familiar with the symmetry properties of these functions. See my other resources for lessons on these precursors.
I made this to use with my further maths gcse group, but could be used with A-level classes too.
Activities included:
Starter:
A set of four questions, effectively equations but presented as visual graph problems, to remind pupils of the symmetry properties of sine and cosine and the fact that tangent repeats every 180 degrees.
Main:
An example to transition from a visual problem to a formal, worded problem, and a reminder of the symmetry properties of sine and cosine.
Five examples of solving trigonometric equations of increasing difficulty, including graphical representations to help pupils understand.
A set of similar questions for pupils to do independently. I’ve made this into a worksheet where the graphs are included, to scaffold the work. Includes an extension task where pupils create equations with a required number of solutions.
Plenary:
A “spot the mistake” that addresses a few common misconceptions.
Printable worksheets and answers provided.

Activities included:
Starter:
A matching activity, where pupils match up names of solids, 3D sketches and nets.
Main:
A link to an online gogebra file (no software required) that allows you to fold and unfold various nets, to help pupils visualise.

A brief look at other prisms and a tetrahedron (the latter has the potential to be used to revise constructions if pupils have done them before, or could be briefly discussed as a future task, or left out)
Then two activities with a different focus - the first looking at whether some given sketches are valid nets of cubes, the second about visualising which vertices of a net of a cube would meet when folded.
Plenary:
A brief look at some more elaborate nets, a link to a silly but fun net related video and a link to a second video, which describes a potential follow up or homework task.
Printable worksheets and answers included where appropriate.

Activities included:
Starter:
A nice ‘puzzle’ where pupils work out three seemingly unrelated multiplication sums (a good chance to practice another non-calculator skill), only to find they give the same answer. Intended to stimulate some discussion about prime factors.
Main:
Four mini-activities, where pupils use one number’s prime factor form to obtain the prime factor form of some related numbers.
An opportunity for pupils to be creative and come up with their own puzzles.

A complete lesson on the interior angle sum of a triangle.
Activities included:
Starter:
Some simple recap questions on angles on a line, as this rule will used to ‘show’ why the interior angle sum for a triangle is 180.
Main:
A nice animation showing a smiley moving around the perimeter of a triangle, turning through the interior angles until it gets back to where it started. It completes a half turn and so demonstrates the rule. This is followed up by instructions for the more common method of pupils drawing a triangle, marking the corners, cutting them out and arranging them to form a straight line. This is also animated nicely.
A few basic questions for pupils to try, a quick reminder of the meaning of scalene, isosceles and equilateral (I would do a lesson on triangle types before doing interior angle sum), then pupils do more basic calculations (two angles are directly given), but also have to identify what type of triangles they get.
An extended set of examples and non-examples with trickier isosceles triangle questions, followed by two sets of questions. The first are standard questions with one angle and side facts given, the second where pupils discuss whether triangles are possible, based on the information given.
A possible extension task is also described, that has a lot of scope for further exploration.
Plenary
A link to an online geogebra file (no software needed, just click on the hyperlink).
This shows a triangle whose points can be moved dynamically, whilst showing the exact size of each angle and a nice graphic of the angles forming a straight line. I’ve listed some probing questions that could be used at this point, depending on the class.
I’ve included key questions and ideas in the notes box.
Optional, printable worksheets and answers included.

A complete lesson on introducing quadratic equations. The lesson looks at what quadratic equations are, solving quadratic equations when there isn’t a term in x, and ends with a more open ended, challenging task.
Activities included:
Starter:
Two questions to get pupils thinking about the fact that positive numbers have two (real) square roots, whereas negative numbers have none.
Main:
A discussion activity to help pupils understand what a quadratic equation is. They are presented with equations spit into 3 columns - linear, quadratic and something else, and have to discuss what features distinguish each.
Examples, quick questions and two sets of questions for pupils to try. These include fraction, decimal and surd answers, but are designed to be done without a calculator, assuming pupils can square root simple numbers like 4/9 or 0.64. Could be done with a calculator if necessary.
Some questions in a geometric context, culminating in some more challenging problems where pupils look for tetromino-type shapes where area = perimeter. There is scope here for pupils to design their own, similar puzzles.
I haven’t included a plenary, as I felt that the end point would vary, depending on the group.
Slides could be printed as worksheets, although everything has been designed to be projected.
Answers included.
