Nannette TaylorExplore the unique properties of 2 and 3 dimensional shapes with this interactive site. Choose from 2-D or 3-D to begin. Each portion of the site steps you through definitions and vocabulary with examples and highlights of important words. Both portions include worksheets for further exploration and constructing different shapes. Note that the site is British so uses the word "breadth" where U.S. math programs usually say "width." Some downloadable handouts are in Word format and others in pdf format. The 3-D shape downloads let you print, fold, and make your own shapes.

emerson ruizThe Shapes Resource on the Birmingham Grid For Learning website is a fantastic Interactive site for reviewing both 2D and 3D shapes.
The site does a good job defining and introducing 2D shapes and the 3D shape section is one of the best resources for understanding 3D shapes.
Investigation of 3D shapes includes an interactive 3D model of each of the 3D shapes that students can control by touching on the control buttons. In addition, each 3D shape has an accompanying net that teachers can print out for the classroom or students can print out and construct 3D shape at home.
This is a great resource to share with other teachers in your school.

Vicki DeaneThis website provides students with the definitions, examples and properties of 1D, 2D and 3D shapes. The site can be viewed on the interactive whiteboard and taught in a guided discovery lesson environment. The lesson includes a worksheet where students can explore their environment and discover the various shapes within different environments. This relates the lesson to home environment and creates meaning for many students. Within this site there are net shapes available to print to allow students to create their own 3D shape. This allows for students to have a fun hands-on activity. The activities that can be created using this site as a tool will link with the Substrand's, two-dimensional space and three-dimensional space in the NSW Mathematics K-6 Syllabus (Board of Studies, New South Wales).

Jessica RobinsonThis would help teachers and parents working with children learning shapes. It provides children with the option to look at both 2 dimensional and 3 dimensional shapes, you choose wich one you want to look at and it explains further into the different shapes and how many sides they have ect. It would be suitable for children at early stage one and stage one levels.

Michelle WebsterThis is a great resource for stage three to explore properites of 3D objects.This is a fantastic site for stage three children to learn the properties of 3D objects including faces, edges and vertices. This site can help children achieve “SGS3.1: Identifies three-dimensional objects, including particular prisms and pyramids, on the basis of their properties, and visualises, sketches and constructs them given drawings of different views” set out by NSW BoS (2002).
Van de Walle (2010) states that when discovering shapes and there properties, it is important to find similarities and differences between the shapes to help classify the objects and to ensure proper names for shapes and their properties are used. Examples of activities that can be done at this stage include sorting shapes into cylinders, prisms, polygons, etc. and describing a shape while the children draw it. -

Susan DonnellyThis is a colourful, interactive resource for the classroom. 3D shapes can be rotated and viewed from difficult angles. The properties of 2D shapes and 3D objects are available including the nets for the 3D visuals. This site would be a useful tool in the classroom for students to refer back to and develop a geometric language.

Jordeigh DunnInteractive websites can be a useful resource when it comes to student involvement within the classroom. This website allows students to explore the properties of both 2 dimensional and 3 dimensional shapes in a fun and informative manner.
In chapter 20, Geometric Thinking and Geometric Concepts, Van de Walle addresses many big ideas about geometry. The main idea is "what makes shapes alike and different can be determined by geometric properties" (2010, p. 399). This statement is very similar to the interactive website, as both address the importance of the properties of all shapes. The website and Van de Walle also explain the differences and similarities between shapes and between 2 dimension and 3 dimensional shapes.
Students, who can understand the basics of shapes and their properties, will in turn be able to further their knowledge and understanding in all areas of geometry. -

Holly de WithThis website is highly relevant to the Space and Geometry strand in many ways. It can be used by teachers and students for revision, as well as a part of lessons with its inclusion of the different properties of 2D and 3D objects. The 2D shape section includes how to find the area of each shape; making it relevant for measurement units as well. While the 3D shapes can be digitally manipulated by rotating them in various directions; this way students can see and/or count the different properties, increasing their engagement.
Digital manipulatives are becoming more frequent with teachers claiming “their teaching is more effective...and that students are more engaged” (Mildenhall, Swan, Northcote & Marshall, 2008, pp.4) when they use them. This is because students are “digital natives” (Prensky, 2001), and, that interactive technology - like digital manipulatives - is proven to “further enrich students’ learning” (Mildenhall, et al, 2008, pp.6). Therefore, this website the perfect tool to use to improve teacher practices. -

michelle linsdellAccording to Van De Walle (2010, p. 197) "with sufficient experiences, students develop classifications of special shapes - triangles, parallelograms, cylinders, pyramids, and so on - and learn that some properties apply to full classes. Eventually they will investigate how properties of shapes impose logical consequences on geometric relationships and the ability to reason about shapes and properties will be developed." This is an excellent activity. It is where 3-D and 2-D shapes are thoroughly explained to the students. There is activity sheets attached to both of the explanations. This is a great way for the teacher to start off a geometry lesson on 2-D and 3-D shapes. Sperry-Smith (2009, p.38) states that "shape is the study of rigid figures, their properties, and their relation to one another. The most common investigations concern the space figures, such as a ball, and the plane-figure (2-D shapes), such as a circle."
