6th Grade Mathematics Curriculum

Units 1, 2, 3, 4, 5, 7, 8, 10

Course Description:The 6th Grade Mathematics course serves as a culminating year for a lot of work with fractions,decimals and percents. Students convert among fractions, decimals and percents as well asperform operations with fractions. Students’ knowledge in the area of algebra continues toexpand to include solving more complicated equations and evaluating more complicatedexpressions. Circles, triangles, and quadrilaterals are all addressed in geometry units while themeasurement focus is on volume and capacity. Finally, students continue their work with thecollection, display and analysis of data and build upon the probability knowledge they developedin 5th grade. Problem solving and communication are emphasized across all these areas.

Course Essential Questions and Big Ideas:

Any number can be represented in multiple ways (fractions, decimals, percents, powers). Youcan make the math easier by choosing the best representation.

Ratios, fractions, percents, and division are just different ways of representing the same process.

Unit 4 Multiplying and Dividing FractionsLength: ~2 weeksTimeframe: Early November

State Standards (Shaded statements are identified as Post-March Indicators):6.N.17 Multiply and divide fractions with unlike denominators6.N.18 Add, subtract, multiply and divide mixed numbers with unlike denominators6.N.20 Represent fractions as terminating or repeating decimals6.N.21 Find multiple representations of rational numbers (fractions, decimals, and percents 0

3 is the same as multiplying by 1/3)

does it mean? Will the quotient be larger or smaller than the whole number?Why?
