Indiana Standards 6th Grade Math Activities

IN.6.1. Number Sense

Students compare and order positive and negative integers, decimals, fractions, and mixed numbers. They find multiples and factors.

6.1.1 Understand and apply the basic concept of negative numbers (e.g., on a number line, in counting, in temperature, in ''owing'').

6.1.5 Recognize decimal equivalents for commonly used fractions without the use of a calculator.

6.1.6 Use models to represent ratios.

6.1.7 Find the least common multiple and the greatest common factor of whole numbers. Use them to solve problems with fractions (e.g., to find a common denominator to add two fractions or to find the reduced form for a fraction).

IN.6.2. Computation

Students solve problems involving addition, subtraction, multiplication, and division of integers. They solve problems involving fractions, decimals, ratios, proportions, and percentages.

6.2.1 Add and subtract positive and negative integers.

6.2.10 Use mental arithmetic to add or subtract simple fractions and decimals.

6.2.2 Multiply and divide positive and negative integers.

6.2.3 Multiply and divide decimals.

6.2.4 Explain how to multiply and divide positive fractions and perform the calculations.

6.2.5 Solve problems involving addition, subtraction, multiplication, and division of positive fractions and explain why a particular operation was used for a given situation.

6.2.6 Interpret and use ratios to show the relative sizes of two quantities. Use the notations: a/b, a to b, a:b.

6.2.7 Understand proportions and use them to solve problems.

6.2.8 Calculate given percentages of quantities and solve problems involving discounts at sales, interest earned, and tips.

IN.6.3. Algebra and Functions

Students write verbal expressions and sentences as algebraic expressions and equations. They evaluate algebraic expressions, solve simple linear equations, and graph and interpret their results. They investigate geometric relationships and describe them algebraically.

6.3.1 Write and solve one-step linear equations and inequalities in one variable and check the answers.

6.3.2 Write and use formulas with up to three variables to solve problems.

6.3.3 Interpret and evaluate mathematical expressions that use grouping symbols such as parentheses.

6.3.4 Use parentheses to indicate which operation to perform first when writing expressions containing more than two terms and different operations.

6.3.5 Use variables in expressions describing geometric quantities.

6.3.6 Apply the correct order of operations and the properties of real numbers (e.g., identity, inverse, commutative, associative, and distributive properties) to evaluate numerical expressions. Justify each step in the process.

6.3.7 Identify and graph ordered pairs in the four quadrants of the coordinate plane.

6.3.8 Solve problems involving linear functions with integer values. Write the equation and graph the resulting ordered pairs of integers on a grid.

IN.6.4. Geometry

Students identify, describe, and classify the properties of plane and solid geometric shapes and the relationships between them.

6.4.1 Identify and draw vertical, adjacent, complementary, and supplementary angles and describe these angle relationships.

6.4.2 Use the properties of complementary, supplementary, and vertical angles to solve problems involving an unknown angle. Justify solutions.

IN.6.5. Measurement

Students deepen their understanding of the measurement of plane and solid shapes and use this understanding to solve problems. They calculate with temperature and money, and choose appropriate units of measure in other areas.

6.5.1 Select and apply appropriate standard units and tools to measure length, area, volume, weight, time, temperature, and the size of angles.

6.5.10 Add, subtract, multiply, and divide with money in decimal notation.

6.5.2 Understand and use larger units for measuring length by comparing miles to yards and kilometers to meters.

6.5.4 Understand the concept of the constant pi as the ratio of the circumference to the diameter of a circle. Develop and use the formulas for the circumference and area of a circle.

6.5.5 Know common estimates of pi (3.14, 22/7) and use these values to estimate and calculate the circumference and the area of circles. Compare with actual measurements.

6.5.7 Construct a cube and rectangular box from two-dimensional patterns and use these patterns to compute the surface area of these objects.

6.5.8 Use strategies to find the surface area and volume of right prisms and cylinders using appropriate units.

6.5.9 Use a formula to convert temperatures between Celsius and Fahrenheit.

IN.6.6. Data Analysis and Probability

Students compute and analyze statistical measures for data sets. They determine theoretical and experimental probabilities and use them to make predictions about events.

6.6.1 Organize and display single-variable data in appropriate graphs and stem-and-leaf plots, and explain which types of graphs are appropriate for various data sets.

6.6.2 Make frequency tables for numerical data, grouping the data in different ways to investigate how different groupings describe the data. Understand and find relative and cumulative frequency for a data set. Use histograms of the data and of the relative frequency distribution, and a broken line graph for cumulative frequency, to interpret the data.

6.6.4 Show all possible outcomes for compound events in an organized way and find the theoretical probability of each outcome.

6.6.5 Use data to estimate the probability of future events.

6.6.6 Understand and represent probabilities as ratios, measures of relative frequency, decimals between 0 and 1, and percentages between 0 and 100 and verify that the probabilities computed are reasonable.

IN.6.7. Problem Solving

Students use strategies, skills, and concepts in finding and communicating solutions to problems.

6.7.7 Select and apply appropriate methods for estimating results of rational-number computations.
