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 States – Common Core State Standards

• ##### K.G – Geometry
• Mathematics

• K.G.6 – Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”

• ##### 1.G – Geometry
• Mathematics

• 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.”)

## 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

• 3.GM.3 – Represent reflections, translations, and rotations by creating and describing patterns

## United Kingdom – National Curriculum

• ##### Year 2 programme of study
• KS1.Y2.G.PS – Geometry - properties of shapes

• Pupils should be taught to:

• KS1.Y2.G.PS.2 – Identify and describe the properties of 3-D shapes, including the number of edges, vertices and faces
