Investigations: Remote Rulers

Do things really get smaller as they get farther away? Can you be sure? This unit provides students with active, hands-on experience exploring links between data from measurements, geometric patterns and algebraic formulas. Students build an understanding of the formulas XY=K (inverse variation) and X/Y=K (direct variation) through mathematical models created from real situations.
