Shape Detective
Name shapes and solids, count sides and corners, and find lines of symmetry.
Looking closely is the whole job in Shape Detective. In the first levels they name basic shapes and count sides and corners. Then they examine solid shapes and count faces, edges and vertices, with dashed lines showing the hidden edges. Every shape is drawn from real coordinates, so what they see is what the answer describes.
Later levels sort quadrilaterals and triangles by their properties, such as right angles, parallel sides and equal sides, check lines of symmetry, and name the parts of a circle. The same game can serve a kindergartner naming a triangle and an older child telling a rhombus from a trapezoid.
What children practice
- Name basic shapes and count their sides and corners
- Name solid shapes and count faces, edges and vertices
- Choose the most exact name for a quadrilateral
- Classify triangles by their sides and by their angles
- Count lines of symmetry and check whether a line is one
- Name the radius, diameter, chord, center and circumference
Levels
- Level 1: Name basic shapes
- Level 2: Sides and corners
- Level 3: Solid shapes
- Level 4: Quadrilaterals and triangles
- Level 5: Lines of symmetry
- Level 6: Parts of a circle
How it works
- Six levels run from basic shapes to the parts of a circle.
- Each question is multiple choice with a drawn shape or solid.
- A wrong answer says try again, and a right answer gives a short explanation of the idea.
- The speaker button reads each question aloud for children who are still learning to read.
Best for: A good fit for kindergarten through grade 7, whether a child is naming first shapes or sorting quadrilaterals.
Tip for parents: Go on a shape hunt around the house. Ask your child to find a rectangle, a cylinder and a shape with a line of symmetry, and tell you how many sides, corners or faces each has.
Questions parents ask
Does it include 3D shapes?
Yes, Level 3 shows solid shapes and asks for their names and for how many faces, edges or vertices they have. Dashed lines show the edges hidden behind the solid, as in a textbook drawing.
What does the symmetry level ask?
Level 5 shows a shape or a letter and asks how many lines of symmetry it has, or whether a dashed line is a line of symmetry. Both question types help children imagine a fold.
Are the circle words difficult?
Level 6 highlights a part of a circle, such as a chord or the center, and asks for its name. It also gives a radius and asks for the diameter, or the other way around.
