I Spy Geometry: A Book of Lines, Angles & Polygons

As one of our end-of-year projects, my students created pictures where they had to hide all of the geometry terms/symbols that they had learned during our geometry unit.  The pictures will then be turned into a class book where they can locate at least 10 of the following geometry terms in their classmates pictures:

• rays
• line segments
• lines
• parallel lines
• perpendicular lines
• intersecting lines
• straight lines
• acute angles
• obtuse angles
• right angles
• scalene triangles
• isosceles triangles
• equilateral triangles
• quadrilaterals
• pentagons
• hexagons
• octagons
• points
• radius
• diameter
• symmetry
• congruent shapes

Here are some student examples:
