Unit Overview
Content Area: Math
Unit Title: Fractions, Decimals, and Percents
Target Course/Grade Level: Sixth Grade
Unit: 4
Timeline: 4 weeks
Unit Summary: Students build on their previous knowledge of fractions, decimals, and ratios and connect
these ideas to percents. They use equivalent forms of fractions, decimals, and percents to solve problems.
Students explore these relationships through the use of area models, bar models, and number lines. These
models allow students to compare and order fractions, decimals, and percents. They apply these
relationships to estimating and solving problems with percents. The ability to convert between fractions,
decimals, and percents is crucial as students become efficient problem solvers.

Opportunities for Differentiation:
Decelerate: Create a poster with common percent and fraction equivalents.
Accelerated: Have students research batting averages for 10 baseball players and write their averages as a
fraction in simplest form. Ask them to compare the decimal and fraction form and explain why they think
the decimal form is used in sports statistic.
Have student pairs write five fractions as decimals that have denominators of 9, 11, 33, or 99 and then
have them look for any patterns between the decimals and fractions.
Teacher Notes: Have students create a number line to compare fractions, decimals and percent.
