It has been engaging for the students - all trying to reach their highest level and competing with their peers while also learning. Thank you very much!" Comment recorded on the 14 September 'Starter of the Day' page by Trish Bailey, Kingstone School: "This is a great memory aid which could be used for formulae or key facts etc - in any subject area. The PICTURE is such an aid to remembering where each number or group of numbers is - my pupils love it! Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield: "I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information." Comment recorded on the 18 September 'Starter of the Day' page by Mrs. Peacock, Downe House School and Kennet School: "My year 8's absolutely loved the "Separated Twins" starter. I set it as an optional piece of work for my year 11's over a weekend and one girl came up with 3 independant solutions." Comment recorded on the 3 October 'Starter of the Day' page by S Mirza, Park High School, Colne: "Very good starters, help pupils settle very well in maths classroom." Comment recorded on the 9 October 'Starter of the Day' page by Mr Jones, Wales: "I think that having a starter of the day helps improve maths in general. My pupils say they love them!!!" Comment recorded on the 8 May 'Starter of the Day' page by Mr Smith, West Sussex, UK: "I am an NQT and have only just discovered this website. I nearly wet my pants with joy. Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School: "What a brilliant website. We have just started to use the 'starter-of-the-day' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources on-line we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun." Comment recorded on the 1 August 'Starter of the Day' page by Peter Wright, St Joseph's College: "Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities. |
Notes:Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Pupils begin by learning the names on the sides of a right-angled triangle relative to the angles. They then learn the ratios of the lengths of these sides and the connection these ratios have with the size of the angles.
Trigonometry Teacher Resources:3D Trigonometry Presentation: A slide presentation (a poem) introducing using trigonometry (including Pythagoras' Theorem) to find lengths and angles on three dimensional shapes. Inverse Trig Calculator: This calculator is designed to find all of the angles for a given trigonometric ratio and show them on a graph. Triangle Solver: Provide and three measurements for a triangle and this application will work out the remaining sides, angles and area. Trig Tour: See angles, in either degrees or radians, on the unit circle and the graph of the trigonometric function. Trigonometry Activities:Which Side?: Arrange the diagrams in groups depending on whether the arrow is pointing to the opposite, adjacent or hypotenuse. Trigonometry: Sine, cosine and tangent ratios are used to find sides and angles in right-angled triangles. Formulae to Remember: The traditional pairs or pelmanism game adapted to test recognition for formulae required to be memorised for GCSE exams. Trig-Pythag Fusion: Problems requiring multi-step solutions using both Trigonometry and Pythagoras' Theorem Trigonometry in 3D: Calculate the lengths of sides and the size of angles in three dimensional shapes. If Then Trigonometry: Finding the exact values of sine, cosine and tangent of angles if given a different trig ratio. Common Trig Ratios Degrees: A self-marking exercise on finding the exact values of sine, cosine and tangent of special angles. Trigonometry Advanced: A self-marking exercise on the sine rule, cosine rule and the sine formula for finding the area of a triangle. Common Trig Ratios Radians: A self-marking exercise on finding the exact values of sine, cosine and tangent of special angles given in radians. Alternatively, for the more advanced student, there is an ever-growing collection of Exam-Style Questions with worked solutions on the topic of Trigonometry. Trigonometry Investigations:Search for Infinity: Manipulate the Lissajou curve to produce a perfectly symmetrical (vertically and horizontally) infinity symbol. Trigonometry Videos:Trigonometry Video: The basic trigonometric ratios are sine, cosine and tangent and are used to find the lengths of sides and the size of angles in right-angled triangles. Trigonometry and Pythagoras: A trigonometry and Pythagoras theorem revision song Common Trig Ratios Video: You may not realise that it is possible to find sin60° or tan45° without a calculator. This video is to help you do the online, self-marking exercise. Three Dimensional Trigonometry Video: When you have mastered trigonometry in two dimensions it is time to practise solving three-dimensional problems. Formulae for GCSE: These are the formulae candidates need to know for the GCSE(9-1) Maths exams.

"Hi, I have looked for something that specifically looks at angles of elevation and depression. Unable to find these as a separate of questions. Do you have a specific of questions relating to this?
Many thanks.
[Transum: Thanks for your comment John. You can find exam-style questions on the Angles of Elevation and Depression page.]"
