Using Trigonometry and Similar triangles to find the distance of the stars and diameter of the Sun

Using Trigonometry and Similar triangles to find the distance of the stars and diameter of the Sun

A worksheet taking students through the parallax method of finding the distance to stars using SOHCAHTOA trigonometry and then an additional task on using similar triangles to find the diameter of the Sun. Suitable for Y9 classes onwards. The idea inspired by the nice resource from Greenwich Observatory: https://www.tes.com/teaching-resource/measuring-the-universe-ks4-11198074 - from which I used a couple of pictures. Check out this resource as well for some more ideas.

Junior Geometry - Topics 1-10

Junior Geometry - Topics 1-10

Bringing together the 1st 10 of 20 Topics in the GetMathsFit Junior Geometry series. This is over 350 pages of worked exemplar, explanation, definition of meaning & concept, exercises and model solutions. The teaching is logical, sequential and thorough without the need to refer elsewhere. From an introduction to points, lines and angles students explore and learn further characteristics, physical skills and reasoning with plane figures, symmetry, parallel lines, Pythagoras, similarity, congruence and finally proofs and problem solving with angles and parallel lines. Use for in-class introductions, group work, plenaries and differentiation as well as a home self study, revision and reference resource.

Pythagoras Theorem (Topic 6): Worked examples, exercises & model solutions

Pythagoras Theorem (Topic 6): Worked examples, exercises & model solutions

Topic 6 of 20 in the Junior Geometry series demonstrates via a series of worked examples the core calculations of Pythagoras Theorem. Moving on to straightforward applications in 2D & 3D this is a self-contained stand alone resource for self-study and practice. The worked exemplars, exercise questions and model solutions make this a very handy plenary, homework or revision resource.

455 Maths revision sheets, 75 Feedback sheets, 11 Topic sheets, 60 Starters

455 Maths revision sheets, 75 Feedback sheets, 11 Topic sheets, 60 Starters

Visit https://www.maths-resources.co.uk to see thumbnail versions of the 455 revision sheets. 455 Maths revision sheets arranged broadly in order of difficulty. Suitable for Years 7 – 11. Wide range of topics covered. Very useful as homeworks. 75 of these have accompanying “Feedback” sheets, which give worked solutions to many of the questions. In many cases the next sheet has the same questions but using different numbers. Students can study their answers using the Feedback sheet and then aim to get a higher mark for the next sheet. Sheets often cover a range of topics, and the constant repetition has proved to be very effective in ensuring that material previously taught is not forgotten. Worksheets on Circles, Indices, Interior and Exterior Angles, Mean, Median, Mode and Range, Multiples, Factors and Prime Numbers, Percentages, Probability, Properties of Quadrilaterals, Ratio and Proportion, Straight Line Graphs and Tree Diagrams are provided by the 11 topic sheets. In many cases these sheets progress from simple recall questions through to more complex problems. The first 14 Starter sheets cover basic numeracy – addition and subtraction, times tables, negative numbers, fractions, square and cube numbers and simple percentages. After this, other topics are covered. Like the revision sheets, the Starter sheets are arranged broadly in order of difficulty. They are supplied as PowerPoint presentations and well as PDFs. Answers are provided for all the revision sheets, topic sheets and starters.
