This lesson covers the full range of attainments for missing angles in a triangle. It starts by recapping prior knowledge on angles on a straight line and around a point before moving onto the basics of angles in a triangle. This lesson allows the topic to be differentiated for a variety of attainment levels and could easily be adapted to meet the need of higher or lower attaining groups through missing out specific examples. The lesson does not look at the specific angle properties of isosceles and equilateral triangles, however, I do have a lesson on this available. This lesson spends time really allowing students to build an understanding of angles in a triangle and build change though the interleaving of previous learning on angles and through the involvement of forming and solving a variety of equations. The lesson includes; Starter Introduction to the topic in small chunks Opportunities to practice basic skills through a collaborative activity. Clear modelling through “I do” and “You Do” examples. Multiple choice questions to draw out misconceptions. Differentiated worksheet. A challenge question. The lesson includes the solutions and is fully animated which will make it perfect for delivering live remote lessons.

This is a whole lesson on Angle Rules and Parallel Lines. This comes as part of a great series on different angle rules. This lesson builds on the first lesson (angles on a straight line and around a point) by looking at corresponding, alternate, and supplementary angle rules. Teaching all the angle rules over more lessons does pay dividends and so this lesson fits into the bigger bundle available on angle rules. This lesson also introduces algebra from the start to get pupils used to it from the get-go and to help develop these core skills. This lesson is ready to go with no prep required. It is also great for home learning and flip learning. 18 slide-presentation + ORIGINAL VIDEO CONTENT + worksheets The lesson comes with: + Starter + Learning objectives (differentiated) + Keywords (different types of angles) + AFL activity + excellent examples + super clear teaching slides + FULL ORIGINAL VIDEO CONTENT (10 MINS) + Differentiated worksheet (with answer key) + Puzzle 'Follow Me' Worksheet + Handout (great for student notes) + plenary All 7 LESSONS on Angle Rules are available as a bundle and All Geometry Lessons as one MEGA BIG BUNDLE are available from the links below: Angle Rules BUNDLE (7 Lessons) Geometry - All Lessons LASTLY: This lesson is flat-packed (limited edited) for copyright purposes.

Worksheet (2 pages) and Homework (1 page) (with answers) for Critical Angle and Total Internal Reflection. Including an explanation of light refracting away from the normal when leaving a denser medium, and how this relates to the critical angle. Calculations for working out the critical angle or refractive index when given one of those two values. Total internal reflection, its uses, and light ray diagrams for fibre-optic cables. A corresponding presentation is free to use and embedded at physics.mrhatchard.co.uk in Section 4 (Waves). Written for the Cambridge IGCSE Coordinated Sciences and Combined Sciences courses, but obviously a large content overlap with various GCSE courses also.

Suitable for both Key stage 3 and 4. This lesson and worksheet is designed to help pupils revise angles in parallel lines. The lesson is fully differentiated featuring a starter, main and plenary for pupils to work through. There are numerous examples, practice problems and challenges for pupils to complete. The worksheet is fully differentiated (mild, medium spicy, hot and challenge) allowing pupils to work at different levels simultaneously. The worksheet also features a section for pupils to self-assess their understanding and set a target for next lesson

A good way to round off the topic of angles with this colouring sheet. Pupils are able to self assess by seeing if their answer is in the colouring area.

everything u need 2 know about angles

In this activity, students will practice applying what they know about angles in quadrilaterals to find the angle or variable indicated. Then, they will color their answers on a pattern with the color indicated to reveal a beautiful, colorful mandala! This no-prep activity is an excellent resource for sub plans, enrichment/reinforcement, early finishers, and extra practice with some fun. It is especially useful for end-of-year practice, spiral review, and motivated practice when students are exhausted from standardized testing or mentally “checked out” before a long break (hello summer!). Color motivates even the most challenging students and the students get a fun chance to practice their essential geometry skills. In addition, the finished products make fabulous classroom decor!

Worksheet attached. Activity: measure each angle and state whether is is acute, right angle, obtuse or reflex. Protractor needed.

This is a problem solving activity/worksheet that tests multiple levels of understanding related to the topic of interior and exterior angles of regular polygons. They are high level problems to test the most able, although a hint/formula sheet is included to help “differentiate down”. The purpose of this activity/worksheet is to provide differentiation, challenge and time saving for teachers. All answers are provided.

Angle rules, straight line around a point, in a triangles, parallel lines and pythagoras, just few quick smart board slides to prompt teaching of these topics

A powerpoint created to make pupils confident with trigonometry Focuses first on labelling the sides with Hypotenuse, Opposite and Adjacent Introduces the trigonometric ratios and ways to remember them Includes many examples so that pupils can see how it is done Includes an activity where pupils must match the questions with their answers (includes solutions for these) Moves onto calculating missing angles using trigonometry and provides opportunity for the discussion of inverse operations

This pack contains two activities to motivate using a protractor and ruler carefully. 1. Impossible Constructions This activity requires students to try and draw a series of shapes, with the knowledge that at least one of them is impossible! For example, can they construct a triangle with two obtuse angles? Why? Why not? 2. Draw that Space Ship! This activity requires students to try and make an accurate version of a space rocket. They must draw lines and angles accurately in order for the spaceships to turn out correctly. There are two different Space Ships for students to work on, of increasing difficulty! Answers are included.

In this activity, students will classify angles (graphic and numerical representations) as obtuse, acute, straight, or right. Then, they will color a pattern according to their answers to reveal a beautiful, colorful mandala! This no-prep activity is an excellent resource for sub plans, enrichment/reinforcement, early finishers, and extra practice with some fun. It is especially useful for end-of-year practice, spiral review, and motivated practice when students are exhausted from standardized testing or mentally “checked out” before a long break (hello summer!). Color motivates even the most challenging students and the students get a fun chance to practice their essential geometry skills. In addition, the finished products make fabulous classroom decor!

This high quality poster is ideal for your classroom wall, bulletin board or math display. It makes a great anchor for students (and teacher) to refer to. I have included 4 designs with different colored tittles to fit your room decor. Angle definitions and examples on the poster are: Acute, Right, Obtuse, Straight, reflex, Full, Adjacent, Complementary, supplementary and vertical. Enjoy.

This is a whole lesson based on the Year 6 Geometry objective of '’Angles in a triangle- special cases. This resource includes the teacher input ( learning journey), independent worksheet and a depth activity to deepen the children’s understanding of the concept being learned. The questions have been inspired and adapted from the White Rose Small Steps Guidance and Teaching for Mastery documents. This document is useful for teachers who have adapted Maths Mastery and need guidance in the approach or those who are looking for variation in fluency, reasoning and problem solving or simply those who don’t want to plan it themselves but want high quality resources and quality first teaching. =) All of the documents that are uploaded as an Activinspire file are interactive and all of the concrete/pictorial manipulative can be used, moved and manipulated. This document can be downloaded on Activinspire and it is also available as a PDF for those who do not have Activinspire. **Please note - these resources are not compatible with Smart Notebook and the PDF file is not interactive. ** Thank you for taking the time to review my resources. =) I hope this helps you with your teaching and if it does please could you be kind enough to leave some positive feedback. =) Kind regards, @MasteryMaths01

I completed these lessons with my year 6 class to practise estimating the size of angles, then measuring their actual size using a protractor. The worksheet for this lesson is differentiated for LA, MA and HA. The second lesson moves onto the class drawing angles using protractors.

A page of protractors with a variety of acute, obtuse and right angles for pupils measure. A great way to introduce protractors and how to use them. This worksheet could easily be used in both Upper and Lower KS2.

A complete lesson on the interior angle sum of a triangle. Activities included: Starter: Some simple recap questions on angles on a line, as this rule will used to ‘show’ why the interior angle sum for a triangle is 180. Main: A nice animation showing a smiley moving around the perimeter of a triangle, turning through the interior angles until it gets back to where it started. It completes a half turn and so demonstrates the rule. This is followed up by instructions for the more common method of pupils drawing a triangle, marking the corners, cutting them out and arranging them to form a straight line. This is also animated nicely. A few basic questions for pupils to try, a quick reminder of the meaning of scalene, isosceles and equilateral (I would do a lesson on triangle types before doing interior angle sum), then pupils do more basic calculations (two angles are directly given), but also have to identify what type of triangles they get. An extended set of examples and non-examples with trickier isosceles triangle questions, followed by two sets of questions. The first are standard questions with one angle and side facts given, the second where pupils discuss whether triangles are possible, based on the information given. A possible extension task is also described, that has a lot of scope for further exploration. Plenary A link to an online geogebra file (no software needed, just click on the hyperlink). This shows a triangle whose points can be moved dynamically, whilst showing the exact size of each angle and a nice graphic of the angles forming a straight line. I’ve listed some probing questions that could be used at this point, depending on the class. I’ve included key questions and ideas in the notes box. Optional, printable worksheets and answers included. Please do review if you buy as any feedback is helpful and appreciated!
