6.1 Algebraic Reasoning

6.1.1 Extend and create patterns from tables, graphs, rules and number properties and generalize patterns algebraically (e.g., recursive patterns like the Fibonacci numbers, number sequences, prime and composite numbers).
6.1.2 Use substitution and order of operations to simplify and evaluate algebraic expressions (e.g., if x = 5 evaluate 2x + 3).

6.2 Number Sense

6.2.1 Multiply and divide fractions and mixed numbers to solve problems using a variety of methods.
6.2.2 Convert, compare and order decimals (terminating and nonterminating), fractions and percents using a variety of methods.
6.2.3 Estimate solutions to single and multi-step problems using whole numbers, decimals, fractions, and percents and assess whether solutions are reasonable (e.g., 7/8 + 8/9 is about 2, 0.9 + 0.3 is about 1).
6.2.4 Build and explore multiples and their patterns to develop the concept of exponents.
6.2.5 Simplify numerical expressions with exponents and parentheses using order of operations.

6.3 Geometry

6.3.1 Angles
6.3.1.a Compare, estimate and determine the measurement of angles.
- Geometry: Angle review: measure and classify (Sixth grade - Y.3)
- Geometry: Estimate angle measurements (Sixth grade - Y.4)
6.3.1.b Find the complement and supplement of an angle.
- Geometry: Complementary and supplementary angles (Sixth grade - Y.6)
6.3.2 Differentiate between congruent and similar figures.
- Geometry: Similar and congruent figures (Sixth grade - Y.14)
6.3.3 Describe the effect of performing basic transformations on objects and figures in a variety of contexts. (e.g., explore reflection [flip] with mirrors, explore rotation [turn] and translation [slide] by designing the layout of different shapes of floor tile).
- Geometry: Reflection, rotation, and translation (Sixth grade - Y.16)

6.4 Measurement

6.4.1 Collect data and develop formulas to find the circumference and area of circles (e.g., use string the length of the diameter of various circular lids to approximate the circumference and develop the concept of pi).
- Geometry: Circles: calculate area, circumference, radius, and diameter (Sixth grade - Y.23)
6.4.2 Compare and convert units within the same measurement system; express conversions using appropriate unit labels (e.g., square inches to square feet, centimeters to millimeters, hours to minutes); and compute measurements of combined units (e.g., 9'8" + 3'6" = ?' and ?" , 150 minutes = ? hours and ? minutes).
- Measurement: Convert and compare customary units (Sixth grade - X.2)
- Measurement: Convert and compare metric units (Sixth grade - X.6)
6.4.3 Find reasonable estimates for measurements using measurements in standard and metric units.
- Measurement: Estimate customary and metric measurements (Sixth grade - X.1)

6.5 Data Analysis and Statistics

6.5.1 Collect, organize, and interpret data to solve problems (e.g., data from student experiments, tallies, Venn diagrams, tables, circle and bar graphs, spreadsheets).
6.5.2 Construct and interpret graphs of statistical data (e.g., explain how different representations lead to different interpretations and may distort information).
6.5.3 Find the median and mode for a set of data in a variety of contexts.
- Statistics: Calculate mean, median, mode, and range (Sixth grade - S.1)
- Statistics: Interpret charts to find mean, median, mode, and range (Sixth grade - S.2)
