Unit G – Triangle Angles
This maths scheme of work for Key Stage Two gets the children to investigate, record and compare the matching properties of different triangle shapes including their sets of right, acute and obtuse angles. The class can produce examples of different isosceles, equilateral and scalene triangles with matching angles.
Investigate, record and compare the matching properties of different types of triangle shapes including their sets of right, acute and obtuse angles
Lesson One : Angle Search
Practise identifying and classifying some of the different types of angles that can be seen in a range shapes found around the school
Lesson Two : Angle Shapes
Explore how to select, record and classify examples of different sized acute and obtuse angles that might be found in a range of geometric shapes
Lesson Three : Angle Match
Investigate how to identify, name and record some of the matching types of angles that can be found in a range of different geometric shapes
Lesson Four : Triangle Groups
Practise recording, classifying and organising some different examples of triangles by their individual matching properties for the number and types of angles
Lesson Five : Triangle Puzzles
Explore how to select and record some special clues that can be used to identify and illustrate a range of different triangles by their matching names and individual properties
-
Ancient Egyptian Pyramids
Explore how and why the Ancient Egyptians constructed and used different pyramids and tombs to reflect their beliefs about the afterlife
-
Earthquakes
Investigate and record some of the different causes and effects of earthquakes on locations around the world
-
Shape Locations
Explain and model how to record and change the co-ordinate positions of some different geometric shapes using translation and reflection movements in the first quadrant.
-
Shape Symmetry
Explore, record and compare the matching lines of symmetry that can be found in a range of different geometric shapes as part of their individual properties
