2D and 3D Geometry (Interactive and Printable Resources)


© R. Mirshahi

Instructions:

  • Click the buttons to go to any of the 4 main areas: 2D, 3D, 2D animated, 3D animated. Then choose any of the 5 practices (buttons on the left side). This may take a few seconds to load. In each practice, you have to sort out 4 shapes or solids by dragging and dropping them into matching drop boxes.

Suggested Lessons or Activities:

  • This is an interactive Geometry resource that can help students recognize and better understand 2D shapes, 3D solids and their properties. It is meant to be used as practice, review, as follow-up to hands-on activities and for teaching purposes. It gives the users instant feedback.

Special Features:

  • 100 different exercises (drag and drop) covering different concepts in Geometry
  • 4 main areas: 2D, 3D, 2D animated, 3D animated (advanced yet very compact 2D and 3D vector animations)
  • questions with increasing complexity
  • Students can point to the animations to pause and see the shapes and 3D models from several different angles.
  • full screen

Printable Resources (Practices and Tests):



Recognition of basic 2D shapes and their properties as well as singular vs. plural and colours.



Recognition of basic 3D solids and their properties as well nets for cubes and square pyramids.




Recognizing and describing of 2D and 3D shapes and their properties, congruent shapes, transformations, etc.




Great exercise involving sorting of 3D solids using a split Venn diagram. Detecting shapes and solids based on partial information given. Recognizing proper and improper nets for basic 3D solids.



Transformations in geometry such as Slide, Turn, or Flip (Translation, Rotations, Reflections), as well as combinations of transformations mapped out on a grid (4 pages).




Recognizing and naming different transformations with the aid of cutout pictures.




Creating motion geometry patterns with cutout pictures as well as recognizing those that are there .




Motion Geometry Patterns: Recognizing transformations like slides, turns and flips in patterns as well as continuing such patterns.




Drawing 2D shaped on dot paper. Describing 2D shapes using a Glossary.




Drawing specific 2D shapes on dot paper from scratch or when completing it when the shape is partially drawn.




Drawing a symmetrical letter on dot paper. Completing symmetrical shapes when half of the shape is given.




(4 pages) Draw lines to break 2D shapes into other shapes.Try to make the multiple shapes congruent (same size and same shape) if possible. You can extend this exercise by creating different puzzles similar to Tangrams. Students can divide and cut the shapes on construction paper and ask a peer to put them back together.




Triangles, rhombuses, and hexagons have been divided a few different ways into smaller shapes on dot paper or using a Geoboard. Students have to identify these component shapes. Also students have to divide squares a few different ways on dot paper.

EQAO Type Questions (Grade 3 Level)

Geometry (1)

This exercise will help the students in the following areas:
  • identify and name 2-D shapes and 3-D figures
  • explore the attributes of 3-D figures (edges and vertices), using skeleton models
  • understand how nets can be folded to make three-dimensional figures
  • explore symmetry using a Geoboard


Geometry (2)

This exercise will help the students in the following areas:
  • explore the attributes of 2-D shapes (number of sides and vertices), using drawings and pattern blocks
  • identify transformations, such as flips, slides, and turns (reflections, translations, and rotations)
  • identify and name 2-D shapes and 3-D figures
  • explore the attributes of 3-D figures (edges and vertices), using skeleton models




Area and Perimeter (1)



This exercise will help the students in the following areas:

  • measure the perimeters and areas of 2-D shapes, and compare the measures
  • match and describe congruent (identical) shapes
  • given the unit cost, calculate the total cost of covering an area




Area and Perimeter (2)



This exercise will help the students in the following areas:

  • measure the perimeter of polygons by adding the lengths of its sides
  • tackle more challenging problems


Grid Paper (Square Grids and Dot Grids):
8 different grids that may be used for practice.
