Students will be able to represent shapes using manipulatives, drawings, and words.
Some of the vocabulary used in this lesson:
Congruent Shapes-Shapes that are the same shape and the same size
Vertex-the point at which the sides of an angle meet (corner, 2 or more corners are called vertices)
Right Angle-a 90 degree angle between two perpendicular lines
Line of Symmetry-when two halves of a figure mirror each other across a line
Area-The extent of a surface or plane figure as measured in square units
Perimeter-the border or outer boundary of a two-dimensional figure (measure each side of a shape and add it together to get the perimeter)
Building with four triangles is the next lesson. Students will do the same activities except with four triangles.
