What a brilliant site you have!!! I love it, especially as it saves me hours and hours of hard work. Others who haven't found your site yet don't know what they are missing!

## United Kingdom – National Curriculum

• ##### Year 3 programme of study
• KS2.Y3.G.PS – Geometry - properties of shapes

• Pupils should be taught to:

• KS2.Y3.G.PS.2 – Recognise angles as a property of shape or a description of a turn

## Australia – Australian Curriculum

• ##### Measurement and Geometry
• Shape

• ACMMG042 – Describe and draw two-dimensional shapes, with and without digital technologies

## New Zealand – National Standards

• ##### 3.GM – Geometry and measurement
• 3.GM.2 – Sort objects and two- and three-dimensional shapes by their features, identifying categories within categories

• ##### 4.GM – Geometry and measurement
• 4.GM.2 – Sort objects and two- and three-dimensional shapes by two features simultaneously

## United States – Common Core State Standards

• ##### K.G – Geometry
• Mathematics

• K.G.2 – Correctly name shapes regardless of their orientations or overall size.

• Mathematics

• K.G.4 – Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).

• ##### 1.G – Geometry
• Mathematics

• 1.G.1 – Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size) ; build and draw shapes to possess defining attributes.

• 1.G.2 – Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.(Students do not need to learn formal names such as “right rectangular prism.”)

• ##### 2.G – Geometry
• Mathematics

• 2.G.1 – Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. (Sizes are compared directly or visually, not compared by measuring.) Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
