The student models transformations. Students then draw a picture of their choice representing the transformation on their card. Students should discuss which properties stay the same, e.g., shape, lengths of line segments, sizes of angles, and parallelism. Clarifying Activity Students use translations, reflections, and rotations to create tessellations with geometry software or paper patterns. The student models transformations.
Students identify the transformation represented in each picture.
Clarifying Activity Students analyze examples of tessellations such as fabric or wallpaper designs, bricklaying patterns, works of art, and patterns in nature and discuss which transformations appear in these tessellations. The student recognizes the connection between ordered pairs of numbers and locations of points on a plane. Clarifying Activity Students choose a partner. One partner secretly places a small washer around a peg on a geoboard. The other partner tries to guess where the washer is by naming the ordered pair that identifies the location of the peg on the geoboard grid.
