7. Unit Overviews – 6th Grade
Unit One – Rational Numbers
This unit combines the skill of dividing fractions with graphing skills both on a number line and on a coordinate grid in a meaningful way for the students.
Unit Two – Ratios and Proportions
Students use reasoning about multiplication and division to solve ratio and rate problems. By viewing equivalent ratios and rates, students connect their understanding of multiplication and division with ratios and rates. Thus students expand the scope of problems they can use multiplication and division to solve, and they connect ratios and fractions. Students solve a wide variety of problems involving ratios and rates.
Big Ideas: The three or four main ideas, conclusions, or generalizations that teachers want their students to discover and state in their own words by the end of the unit. These are concepts students should remember long after instruction ends.

8. Unit Overviews – 6th Grade
Unit Three – Evaluating Expressions
Students understand the use of variables in mathematical expressions. They will write, use, solve and evaluate expressions that correspond to given situations. Students will understand that expressions in different forms can be equivalent and use the properties of operations to rewrite expressions in equivalent forms.
Unit Four – Solving Equations and Inequalities
Students write equations that correspond to given situations and use formulas to solve problems. Students know that the solutions of an equation are the values of the variables that make the equation true. Students use properties of operations and the idea of maintaining the equality of both sides of an equation to solve simple one-step equations and inequalities.

9. Unit Overviews – 7th Grade
Unit One – Operations with Rational Numbers
Students develop a unified understanding of numbers, recognizing fractions, decimals (finite or repeating), and percent as different representations of rational numbers. Students extend addition, subtraction, multiplication, and division to all rational numbers, maintaining the properties of operations and the relationship between addition and subtraction and multiplication and division.
Unit Two – Percent Problems
Students extend their learning of ratios and develop understanding of proportionality to solve single-and multi-step problems. Students use their understanding if ratios and proportionality to solve a wide variety of percent problems.

10. Unit Overviews – 7th Grade
Unit Three – Expressions, Equations, and Inequalities
Students use the arithmetic of rational numbers to formulate, use, and solve expressions and equations with one variable.
Unit Four – Functions and Proportionality
Students extend their understanding of ratios and develop understanding of proportionality to solve single or multi-step problems and to solve a wide variety of percent problems (discounts, interest, taxes, and percent increase or decrease). Students solve problems about scale drawings by relating corresponding lengths between objects or by using the fact that relationships of lengths within objects are preserved in similar objects. Students graph proportional relationships and understand the unit rate informally as a measure of steepness of the related line, called the slope, They distinguish proportional relationships from other relationships.

Unit One – Geometry
Analyze two- and three- dimensional space and figures using distance, angle, similarity, and congruence.
Unit Two– Exponents, Roots, and Pythagorean Theorem
Students understand the statement of the Pythagorean Theorem and its converse and can explain why the Pythagorean Theorem holds, for example, by decomposing a square two different ways. They apply the Pythagorean Theorem to find distances between points on a coordinate plane.

12. Unit Overviews – 8th Grade
Unit Three – Solve Equations
Students strategically choose and efficiently implement procedures to solve linear equations in one variable, understanding that when they use properties of equality and the concept of logical equivalence they maintain the solutions of the original equation.
Unit Four– Functions
Students grasp the concept of a function as a rule that assigns to each input exactly an output. They can translate among representations and partial representations of functions (noting that tabular and graphical representations may be partial representations), and they describe how aspects of the function are reflected in different representations

An APT is a performance assessment that involves a real-world context, where the tasks are either replicas of or similar to the kinds of problems faced by adults, consumers, and professionals in the field.

14. Engaging Scenario - Example
7th Grade Your friend has not been at school for the past few days due to a terrible cold. You, being a great friend, don’t want them to fall behind. You have decided to create a video presentation on negative integer rules that your friend can watch before they come back to school. You will create a 5 minute video using the Educreation application on the web illustrating the number line, opposites, and additive inverses. The video will show the negative integer rules for adding, subtracting, multiplying, and dividing integers with multiple examples for your friend to see how you applied the rules. Make sure you point out some common mistakes that people make when doing these problems.
The Engaging Scenario is an interesting and compelling hypothetical situation provided to students at the start of each unit. It is designed to capture students’ imaginations and help them to buy into the lesson ahead.
