Shape, Shape and Measures – Angles
Geometry Inventor
Through discussion and practical activities appreciate how
to identity and label angles using appropriate notation SP11
5
Could do some work before using the protractor.
Measure and record angles; Acute, Obtuse, Reflex
SP12
Is there some case for those who are having difficulties
actually using a protractor???
Draw a range of angles; Acute, Obtuse, Reflex
SP13
(*Angle Measure – Microsmile)
Explore through practical activities angle relationships
associated with straight lines, intersecting lines and parallel
lines
SP14
6
Understand and use angle properties of intersecting lines
and parallel lines. Use and extend the appropriate language,
for example corresponding, alternate and transversal SP15
Use drawing packages to draw polygons
8
SP16
Very easy in the programme
Develop an understanding of the trigonometric ratios, sine,
It is possible to construct scale drawings in this programme
cosine, and tangent and apply these to right angled triangles then use the measuring tools to complete answers.
in two dimensions. SP20

Shape, Shape and Measures – 2D / 3D
Geometry Inventor
Through discussion and practical activities investigate the
properties of triangles, sides, angles, symmetry,
tessellations and congruence
SH11
5
Reflect a two dimensional shape about a line
SH 12
Through discussion and practical activities investigate the
properties of triangles, sides, angles, symmetry,
tessellations and congruence
SH 13
Recognise and use rotational symmetry. Understand centre
and order
SH 14
6
Compare and classify triangles, quadrilaterals and other
polygons in terms of their properties
SH 15
Understand and use language associated with the circle,
circumference, radius, diameter, arc and chord
SH 16
7
Could be a demonstration tool for this
Develop an understanding of Pythagoras’ Theorem and
apply it in two dimensions

Shape, Shape and Measures – Transformations
Geometry Inventor
Rotate a two dimensional shape about a given centre such
as a vertex, in order to develop and consolidate their
properties.
SR1
6
Translate a two dimensional shape, initially within
tessellating pattern, in order to develop and consolidate the
concept of congruence.
SR 2
Enlarge a two dimensional shape, about a given centre of
enlargement, by a whole number scale factor. Discuss
similarity of shapes.
SR 3
7
Enlarge a two dimensional shape, about a given centre of
enlargement, by a positive fractional scale factor.
Consolidate the concept of similarity by discussing the ratio
of the sides of the shapes.
SR 4
Others:
Coursework simulations – Fencing Problem / Guttering where you can create a rectangle of a set perimeter, then set up a
spreadsheet and a graph to record gradual changes to the diagram.
Possible to model questions and acquire the answer using the tools of the programme.
Scale drawing, Area, Pythagoras’ Theorem and Trigonometry.
