    Prism

    This one is a triangular prism: two matching triangles joined by three rectangles, like a tent.

      How it works

      This shape wheel has 23 shapes on its slices: 16 flat ones, from Circle to Decagon, and 7 solid ones, from Sphere to Pyramid. Spin it and the card describes the shape. The wheel names shapes; it does not draw them.

      Three ways to use it in class

      Spin, then ask everyone to draw the shape, find one in the room, or name an object with that shape. Tap Flat shapes for younger children. Switch to Elimination and every shape comes up once before any repeats.

      Flat shapes and solid shapes

      A flat shape has sides and corners. A solid shape has faces you can touch, such as the six squares of a cube. The shape spinner keeps the two in separate groups, so a lesson on solids can spin only the seven.

      Tips
      • For an art warm-up, spin three times and build a picture from only those shapes.

      Questions and answers

      Which shapes are on the random shape wheel?

      Flat: circle, oval, semicircle, triangle, square, rectangle, rhombus, parallelogram, trapezoid, pentagon, hexagon, heptagon, octagon, decagon, star and heart. Solid: sphere, cube, box (rectangular prism), cylinder, cone, pyramid and triangular prism.

      How many sides does a heptagon have?

      Seven. A pentagon has five sides, a hexagon six, an octagon eight and a decagon ten. The card under the wheel gives the number for every polygon it lands on.

      What is the difference between a square and a rhombus?

      Both have four equal sides. A square also has four right angles, so it stands up straight. A rhombus can lean to one side, which is why people call it a diamond.

      Solid shapes 7

      • Box Its math name is rectangular prism: six rectangular faces, like a brick.
      • Cone One circular base and a point at the other end, like an ice cream cone.
      • Cube A box whose length, width and height are equal: six square faces.
      • Cylinder Two matching circles, top and bottom, joined by a curved side, like a can.
      • Prism This one is a triangular prism: two matching triangles joined by three rectangles, like a tent.
      • Pyramid A flat base with triangle sides that meet at one point.
      • Sphere Round like a ball, the same distance from the center in every direction.

      Flat shapes 16

      • Circle Perfectly round, with no corners. Every point on its edge is the same distance from the center.
      • Decagon Ten straight sides.
      • Heart Two rounded tops and one point at the bottom.
      • Heptagon Seven straight sides.
      • Hexagon Six straight sides, like one cell of a honeycomb.
      • Octagon Eight straight sides, like a stop sign.
      • Oval A stretched circle, like an egg or a running track.
      • Parallelogram Four sides in two parallel pairs.
      • Pentagon Five straight sides and five corners.
      • Rectangle Four sides and four right angles. Opposite sides are the same length.
      • Rhombus Four equal sides, like a square pushed over. Often called a diamond.
      • Semicircle Half a circle: one curved edge and one straight edge.
      • Square Four equal sides and four right angles.
      • Star Points all round a center. Five points is the one most people draw.
      • Trapezoid Four sides, with one pair parallel and the other pair not.
      • Triangle Three straight sides and three corners.
      How this list was compiled

      Twenty-three shapes in two groups, put together for this site on 2026-09-30. The side counts and the properties of the polygons, the four-sided shapes, the circle and the solids were checked on 2026-09-30 against OpenStax, Contemporary Mathematics, 10.4 Polygons, Perimeter, and Circumference (https://openstax.org/books/contemporary-mathematics/pages/10-4-polygons-perimeter-and-circumference) and 10.7 Volume and Surface Area (https://openstax.org/books/contemporary-mathematics/pages/10-7-volume-and-surface-area), OpenStax, Prealgebra 2e, 9.4 and 9.6 (https://openstax.org/books/prealgebra-2e/pages/9-4-use-properties-of-rectangles-triangles-and-trapezoids and https://openstax.org/books/prealgebra-2e/pages/9-6-solve-geometry-applications-volume-and-surface-area), and the polygon names table, the square and the pyramid pages of Math Is Fun (https://www.mathsisfun.com/geometry/polygons.html). Oval, star and heart are everyday shape names, not mathematical terms, and their lines only describe how they look. The lines are in our own words. Licence: own work
