Find the missing angles in each of the polygons. Students will need to know how to work out the total angle sum in each polygon before they attempt this worksheet.
Angles are all multiples of 5 so this could be done without a calculator.
Finishes with some work on regular polygons.
Names of 2D shapes worksheet. I find these worksheets very useful to give the pupils as homework’s; they can be trimmed and then stuck into exercise books. The pupils like them and they save on marking time. You will need to change the school logo to your own.
This activity gets students to construct regular polgons and stars using protactor and ruler. It quickly moves onto a powerful online microworld to make the constructions. Students can then discover the rules for a) the sum of exterior angles of a regular polygon and b) the exterior angle of any regular polygon or star.
A visual unit that can be used to promote thinking and encourage group discussion about the properties of polygons. Pupils can use the information provided to accurately draw diagrams to represent equilateral, isosceles, right-angled and scalene triangles along with many regular quadrilaterals.
The activity consists of information sheets, an interctive whiteboard activity and worksheets on polygons, trianlgles and quadrilaterals.
Ideal for KS3 students.
I created this activity for my bottom set Year 9s - who loved it! I made 12 horses labelled 1-12 and blue-tacked them to the board. Each pupil picks a horse. Using 2 dice each horse moves across one space when its number is rolled. It quickly showed the pupils which numbers were more likely to come up when 2 dice are rolled. When playing again I removed some of the 'winning horses'
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.
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.
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! :-)
Investigation and problem solving activity in which students identify all the different pentominoes, then fit them into shapes (50 different shapes, inc. 4 rectangles, 4 squares, 17 animals, 13 pictures (inc. car, train, plane, rocket, boat), 12 other shapes (inc. cross, yin and yang, heart)).
Adventure game in which students answer KS3 circle questions in order to rescue a princess. Teacher notes and answers are provided. There are 5 sections, each with 2 topics. They have 4 attempts at each topic, if they get all 4 wrong, the game ends and they will have to start again. The 5 sections are: parts of a circle, circumference, area, reverse questions: given circumference, find diameter and radius; given area, find radius and diameter. Go to my profile page to see the GCSE version including arc length and sector area and check out my other games.
