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. The five Investigations units from EQUALS give middle school teachers and students opportunities to explore mathematics skills and concepts in familiar contexts that make sense. These 4-8 week integrated units encourage sustained work that involves students in high-level thinking, creative problem solving, planning their own approaches, and communicating their own ideas. They work together to explore problem-based curriculum with more depth than traditional exercises. Student worksheets are in English and Spanish.
