Secondary maths collection
Welcome secondary maths teachers! Are you looking for quality assured resources, designed to make lesson planning easier? Spanning across multiple topics and key stages, this extensive collection, hand-picked by members of the Tes maths panel, is the perfect starting point...
Hand-picked by:
Introducing right-angled trigonometry
Lesson presentations and activities
The PowerPoint is a full sequence of lessons on introducing trigonometry and how to use it. The Recording Ratios document is needed for the discovery lesson, and the Loop Cards are useful as a plenary to this topic of work. Let me know what you think.

Thank you, an excellent resource, will be really useful for remote delivery
Two complete lessons with differentiated activities on discovering trig ratios at GCSE, including using a table of tangent ratios (before getting used to the calculator method). There is a practical activity to try as well as a problem solving activity taken from an OCR specimen paper. (The differentiation is labelled as shape groups from lowest ability to highest: triangle, square, parallelogram, trapezium, pentagon, hexagon respectively). Resources within the lessons are a mixture mixture of my own and other people's - happy to credit individuals if they let me know.

Thank you for publishing your resource. It has been selected to be featured in a new secondary maths collection.
PowerPoint presentation to introduce the topic of trigonometry, either at KS3 or GCSE level maths. Includes background behind why we use trigonometry, some examples with answers, with a question for students to complete at the end. Includes a recap of everything learned.
Brilliant for students with no previous understanding of trigonometry, or those looking to revise/re-learn the basics.Reviews

Perfect! Just what I was looking for. Thank you so much!
Complete lesson to introduce trigonometry and finding the missing sides. Hopefully you will find it of use. Please let me know what you think?

Great images and position of triangles for our Geometry class. Thanks for sharing and saving me time in creating my own images. Love when we help one another.

Excellent resource, just what I was looking for. Thank you for saving me time and sharing yours.
A bingo style activity to reflect on which trigonometric ratio to use given certain sides/angles within right-angles triangles.
To be used as a plenary to a start lesson or as a main reflection activity when putting trig ratios into practice.
N.b. I am an NQT so all feedback is welcomed for my shared resources.Reviews

this is very helpful thanks...
Practice questions, homeworks and assessments
Used this for an interview lesson. Give a third of the group the sin sheet (print on blue), a third cos sheet (print on yellow) and a third the tan sheet (print on white). Get the students to measure the angles in the triangles and two of the sides (dependent on which sheet they have). Then get them to put the values into the calculator to discover the sin, cos, tan features. Introduce SOH CAH TOA and build from there. Updated with PDFs as requested

Brilliant Powerpoint for introducing trig following on from pythag. - I was able to adapt it easily to use with both a foundation and higher class - thank you!
These two worksheets should be printed out. It has been scaled so that when pupils measure with a ruler each 'box' is 1cm x 1cm. Pupils take the required measurements and are asked if they have observed any similarities between O/A. The tan ratio is then introduced! Lots of calculator use is encouraged. Find out the tan of 30º, what about 45º? 1? What does that mean? Feedback would be appreciated as I am a student teacher.

Great way to secure relational understanding of trigonometry as opposed to just a procedural approach.
