A mixture of missing angle and side length questions for higher students (Pythagoras, Trigonometry, Sine and Cosine Rules). A flow chart is included to help students to decide how to determine the unknowns.<br />
<br />
Print on coloured paper and laminate for repeated use. To easily differentiate, ask students to sort triangles into groups according the formula needed & work from left to right on the flow chart. <br />
<br />
Questions collected from a variety of on-line sources.<br />

This PowerPoint contains a whole lesson introducing the topic of matrices, specifically what matrices are, order of matrices and how to put data in matrix form. Then starting to look at some basics, such as how to add and subtract matrices. It also looks at how a scalar is used, and goes through examples of questions like 3a + b.<br />
<br />
The PPT contains a starter, various examples, lesson objectives, key words, questions, answers and plenary. I have found this resource to help me structure the lesson effectively, keep the flow and successful in helping pupils progress and get a good foundation for future lessons on matrices.
