  1. 2. A specific position on a line, plane, or in space.
  2. 4. A flat two-dimensional surface upon which two-dimensional objects (e.g., circle, square) can lie, or the face of a three-dimensional object as it creates a surface (e.g., face of a cube); the dimensions of which are infinite.
  3. 5. A closed figure with eight sides.
  4. 6. Having curvy or undulating attributes (e.g., ocean, octopus tentacles).
  5. 10. Surface planes of three-dimensional shapes.
  6. 14. A closed figure with three sides.
  7. 15. Two lines that meet to make a corner.
  8. 18. Identical in size and shape.
  9. 20. Sides that are the same length.
  10. 21. A closed figure with seven sides.
  11. 22. Line segments in geometric figures compose the exterior of the object.
  12. 23. A two-dimensional shape in which all points on the curved line are equidistant from a center point.

  1. 1. Terminology to describe the dimensions of an object or set. With young children, the terms large, medium, small, taller, shorter, longer, less than and greater than are all appropriate.
  2. 3. A closed figure with six sides.
  3. 7. Also known as corner/corners. The point at which two sides of a two-dimensional figure or two edges of a three-dimensional figure meet.
  4. 8. A closed figure with five sides.
  5. 9. Without a curve.
  6. 11. Two lines in a two-dimensional space that do not meet (for example, the opposite sides of a square). A parallelogram has two sets of parallel lines.
  7. 12. Has a plane-like quality.
  8. 13. A two-dimensional, closed, four-sided figure with four right angles.
  9. 16. The meeting of two faces in a three-dimensional shape.
  10. 17. A special type of rectangle that has equilateral (same length) sides and parallel opposite sides.
  11. 19. An informal word to describe the angles of objects.
  12. 24. A closed four-sided figure with parallel opposite sides. A square is a special kind of rhombus. Sometimes called a diamond.
