## KS3 Maths Angles in a triangle animation

Powerpoint suitable for KS2 and KS3 Maths: Shape, space and Measure / Geometry - Triangle properties. This animation shows how angles in a triangle lie and a straight line and therefore add up to 180. I usually get students to test this out with their own card triangles and use this animations as a summary.

I like this as it shows clearly how and why the angles in a triangle add up to 180 degrees. You could get the pupils to do this with paper too. Nice to start off a lesson on angles showing this and starting a discussion.

#### Calculate missing angles in a triangle - KS3/GCSE

Get learners in pairs or groups to discuss how we calculate a missing angle in a triangle. Then ask learners how we would use or knowledge to solve the problems involving algebra. When learners say form an equation remind them how to solve using the balance method. For this particular task we completed them on posters for a display to show the challenges we had worked on.

#### Plans and Elevations - Famous Buildings

A PowerPoint of images showing the plans and elevations of famous buildings (one of the slides is the science block in my school but you could swap this). Ideal for KS3 and GCSE classes.
I found the images using google satellite maps and print screened once I had zoomed in.
It was a really nice starter activity to get the students engaged. Hopefully they now know the difference between a plan and an elevation.
This task could be extended by getting students to draw elevations of the given building, even scale drawings

#### Differentiated Activities for Angles NEW Updated 2016 (LKS2 -2014 Objectives)

There are about 17 (practical and fun) lesson activities, tasks or worksheets to cover the following 2014 objectives: <br />
Recognise angles as a property of shape or a description of a turn.<br />
Identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle. <br />
This is one of the children's favourite activities to help understand angles. Ideas for children of all abilities to have fun learning about angles.<br />
Thank you for downloading. Please look for the large files (Flip -chart and PDF) which contain all the resources without the Paws & Clause watermark. <br />

#### Coordinate Battleships Game (Differentiated)

A self-contained game to be played in pairs.<br />
<br />
Use to revise reading coordinates on a grid. Best played once coordinates have already been introduced, as a consolidating activity.<br />
<br />
Differentiated versions of the game within this pack, including use of the first quadrant only, as well as all four quadrants. You will also find instructions on how to play the game within your pack. Suitable for Years 4 and 5 (on one quadrant) and Year 6 and KS3 (on all four quadrants).<br />
<br />
You will find a PDF version and editable Word version available for download; both are exactly the same, so download whichever is more convenient for you.

#### Plotting coordinates using up to four quadrants!

I have created this for a year 5 top set maths group. It is differentiated 3 ways, yellow being the less able, green able and pink more able.<br />
<br />
This links in very heavily with shape as I am teaching this following 3 weeks on shape, space and measure, so it will continue to embed their knowledge of quadrilaterals, types of triangles, angles and parallel and perpendicular lines.<br />
<br />
Hope this is useful! Have included photos of what it should look like once points have been plotted, hopefully I haven't made any silly mistakes! :-)
