The student will identify representations of a given percent and describe orally and in writing the equivalence relationship between fractions, decimals, and percents. The student will compare and order whole numbers, fractions, and decimals, using concrete materials, drawings or pictures, and mathematical symbols. The student will compare, order, and determine equivalent relationships between fractions, decimals, and percents, including scientific notation. Students can use a spreadsheet to organize and group equivalent fraction, decimal and percent representations of given numbers.
Students can enter formulas to generate the different forms.
Comparing graphs of the various representations will allow students to visually note their equivalence or relative size. Resource ClarisWorks or other spreadsheet program with graphing capabilities. The student will simplify expressions by using the order of operations, mental mathematics, and appropriate tools. Exponents will be included. The student will simplify numerical expressions involving exponents, using the order of operations.
