Grade 7In Grade 7, students focus on four critical areas: (1) developing understanding of and applying proportional relationships; (2) developing understanding of operations with rational numbers and working with expressions and linear equations; (3) solving problems involving scale drawings and informal geometric constructions, and working with two- and three-dimensional shapes to solve problems involving area, surface area, and volume; and (4) drawing inferences about populations based on samples.

Scope & SequenceYear-Long Scope & Sequence
Year-Long Overview & Pacing Guide 7.1 Rational Numbers
In this unit, students explore adding and subtracting integers with models, number lines, and arithmetic. They generalize these integer rules and extend them to all rational numbers. Next they use number lines and multiplication patterns to find products and quotients of rational numbers. Properties of addition are reviewed and then used to prove rules for addition, subtraction, multiplication, and division.
7.2 Proportional Relationships
In this unit, students use real-life situations to explore proportional relationships using tables, equations, and graphs. They realize that a proportional relationship is represented on a graph as a straight line that passes through the origin and that there are straight-line graphs that do not represent a proportional relationship. They next look at rates expressed as fractions, nding the unit rate (the constant of proportionality) and then using the constant of proportionality to solve a problem. In the second part of the unit, students work with percentages. First, percentages are tied to proportional relationships, and then students examine percentage situations as formulas, graphs, and tables. Students explore salary increase, see the similarities with sales taxes, and then go on to explore percent decrease. 7.3 Constructions and Angles
In this unit, students define adjacent, supplementary, complementary, and vertical angles and then explore how they are manifested in quadrilaterals. Next, students explore triangles and their properties with certain known and unknown elements. Through exploration, students discover that the sum of the measure of the interior angles of a triangle is 180° and that the sum of the measures of the interior angles of a quadrilateral is 360°. They explore other polygons to find their angle sum and determine if there is a relationship to the angle sum of triangles. This extends to finding the measure of the interior angles of regular polygons and speculating about how this relates to a circle. 7.4 Zooming In On Figures
In this unit, students extend their learning about polygons and circles. They will compare circles with regular polygons and come up with area formulas, learn about three-dimensional figures, and explore the relationship between two-dimensional and three-dimensional shapes. Students will apply this knowledge to design and build model buildings. At the end of the unit, the buildings will be combined to make a model city.
7.5 Algebraic Reasoning
In this unit, extend their learning about expressions and equations. They will write, evaluate, and simplify expressions that contain positive and negative numbers. Students will write algebraic expressions and equations to represent situations and then solve them using formal algebraic methods and number properties. Students will learn how linear inequalities are different from linear equations, they will use inequalities to represent real-life situations, and they will find solutions to these problems by writing and solving inequalities. 7.6 Samples and Probability - CURRENT UNIT
In this unit, students work with line plots, box plots, and measures of center and spread. They use these tools to compare similar data sets and learn to use random samples to generalize about a population. Students will learn the difference between simple probability, compound events, and experimental versus theoretical probability.
7.7 Putting Math to Work
In this unit, students use their spatial reasoning and visualization skills to find the least number of cubes needed to construct a structure. They will understand the relative speeds of birds, flying squirrels and dolphins, find the volume of the Great Lakes, and then graphically represent a virtual journey through the locks of the Welland Canal. | ||||||||||||||||||||
