In Part l of this two-part lesson, students use an interactive to place percent increase and percent decrease signs between monetary amounts to indicate the correct increase or decrease between the amounts of money. They must also place the correct decimal multiplier between the two amounts to show what decimal to multiply the original amount by to get the final amount.
Students apply understanding of percent change situations to systematize and generalize patterns in relating two amounts by multiplication.
