The search for patterns is fundamental to mathematics at all grade levels. Patterns help children see order and make sense of the underlying structures of things, situations, and experiences. Patterns help children make predictions. Students measure geometric figures and visualize and represent shapes. This work leads to generalizations such as formulas for area and perimeter.
Students make a triangle on the grid.
Students make a triangle twice as big and four times as big as the first one. Students do the same with a square.
