In
this lesson, students use real-world models to develop an understanding
of fractions, decimals, unit rates, proportions, and problem solving.
The three activities in this investigation center on situations
involving rational numbers and proportions that students encounter at a
bakery. These activities involve several important concepts of rational
numbers and proportions, including partitioning a unit into equal
parts, the quotient interpretation of fractions, the area model of
fractions, determining fractional parts of a unit not cut into
equal-sized pieces, equivalence, unit prices, and multiplication of
fractions.
