Colourful differentiated ONESIE worksheet. Allowing students to show progression. Suitable for cover lessons - easy and cost effective to photocopy.
**Supplied with answers.**

BUNDLE

This is a set of 4 mastery worksheets on trigonometry involving the Sine rule, Cosine rule, area of triangles using trigonometry and exact trig values.
Each worksheet is split into 3 sections, fluency, reasoning and problem solving so students can master the topic.
All answers are included for the questions.

A complete lesson on using SOHCAHTOA and Pythagoras’ theorem with problems in three dimensions.
Activities included:
Starter:
A set of recap questions on basic SOHCAHTOA and Pythagoras.
Main:
Examples and questions to dscuss, on visualising distances and angles within cuboids and triangular prisms, and understanding the wording of exam questions on this topic.
Examples and quick questions for pupils to try, on finding the angle of a space diagonal.
A worksheet, in three sections (I print this, including the starter, two per page, two sided so that you have a single page handout), with a progression in difficulty. Starts with finding the space diagonal of a cuboid, where the triangle pupils will need to use has been drawn already. The second section looks at angles in a triangular prism, and pupils will need to draw the relevant triangles themselves. The third section has exam-style questions, where pupils will need to identify the correct angle by interpreting the wording of the question. (eg “find the angle between the diagonal AE and the plane ABCD”).
An extension task looking at the great pyramid of Giza.
Plenary:
A final question to add a bit more depth, looking at the most steep and least steep angles up a ramp.
Printable worksheets and worked answers included.
Please review if you buy as any feedback is appreciated!

A complete lesson on using and applying Trigonometry to right angled triangles which is suitable for the new curriculum.
Pupils are given the chance to master the fluency of this topic aswell as work on reasoning and problem solving tasks.
All tasks are differentiated to 3 levels all with solutions and offer lots of consolidation as well as alot of challenge. Can be used with KS3/KS4.

A complete lesson on using sin, cos and tan to find an unknown side of a right-angled triangle. Designed to come after pupils have been introduced to the trig ratios, and used them to find angles in right-angled triangles. Please see my other resources for complete lessons on these topics.
Activities included:
Starter:
A quick reminder and some questions about using formulae triangles (e.g. the speed, distance, time triangle). This is to help pupils to transfer the same idea to the SOHCAHTOA formulae triangles.
Main:
A few examples and questions for pupils to try, on finding a side given one side and an angle. Initially, this is done without reference to SOHCAHTOA or formulae triangles, so that pupils need to think about whether to multiply or divide.
More examples, but this time using formulae triangles.
A worksheet with a progression in difficulty, building up to some challenging questions on finding perimeters of right-angled triangles, given one side and an angle.
A tough extension, where pupils try to find lengths for the sides of a triangle with a given angle, so that it is has a perimeter of 20cm.
Plenary:
A prompt to get pupils thinking about how they are going to remember the rules and methods for this topic.
Printable worksheets and answers included.

The introduction sheet is designed to be used as a class activity to learn about bearings and then solving problems involving bearings using trigonometry.
The second sheet is a worksheet with a mix of problems involving trigonometry and bearings (answers included).

A flow diagram that will help pupils decide if they should use Pythagoras or Trigonometry.

TES PICKS

Two trigonometry codebreakers that both involve a terrible joke. The first one is with right-angled triangles, the second requires the sine rule, cosine rule and area of a triangle using trigonometry.

This worksheet separates out the trig questions, and first asks pupils to fill in theta, opposite, adjacent and hypoteneuse, then write out with trigonometric ratio they are using.
Scaffolding to solve problems.

TES PICKS

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.

A set of matching activities to help students practise finding the missing sides and angles in triangles using SOH CAH TOA.
This pack includes four activities:
1. Label the Sides Worksheet
A quick activity for students to label the sides as opposite, adjacent or hypotenuse to get them ready for using SOH CAH TOA.
2. Matching Activity 1 (Sin & Cos)
Students must use the sine and cosine ratios to find the missing sides in a set of triangles.
3. Matching Activity 2 (Sin, Cos & Tan)
Students must use sine, cosine and tangent ratios to find the missing sides.
4. Matching Activity 3 (Angles)
Students must calculate the missing angles in a set of triangles and match them to their answers.
All activities include answers and are easy to check as students can record their answers in a table, meaning you can quickly assess if they are on the right track.

Whole lesson on Angles of Elevation and Depression for high ability year 10 groups. Can be adapted to suit.
Lesson includes:
Starter - Assess current ability and introduce new use of trigonometry.
Main activity - Differentiated so that students can choose to either draw their own diagrams and check against the diagrams provided, or match the diagrams and build their answers from them.
Plenary - Find and correct the mistakes - approaching misconceptions and common errors.
Flipchart - Including examples and board work to introduce the topic.
Lesson can last over 2 full lessons, to enable adaptation to strengths and weaknesses of the class.

BUNDLE

Lessons covering
Right angled trigonometry

Detailed lesson plan with presentation, assessment, worksheet, answers, differentiation, starter and plenary

Complete revision mat covering all of the foundation trigonometry topics in the new 1-9 specification.
Covers trigonometric ratios, calculating sides and angles using trigonometry, angles of elevation, exact trig values and applied problems where a diagram needs to be drawn.
Complete with answers.
Please note I have not rationalised the exact trig values, they are taken from the diagram.

This PPT is ideal for introducing trigonometry to higher tier GCSE Mathematics students. It covers:
Basic trigonometry using SOHCAHTOA
3D Trigonometry
Advanced Trigonometry
A poster which can be used by students to understand when to use different trigonometric methods

Notes, examples, questions and answers illustrating the use of trigonometry in solving problems. Diagrams are given for many of the questions but some problems are included which require the construction of a sketch diagram. This unit of work is suitable for self-study and ranges from beginner to GCSE level.
Three exercises containing a total of over 60 questions (with separate answers) are included in this resource of 20 A4 pages.

This is the original resource for the following topics
