Description:

The projects are meant to connect the world of math to that of art. They allow students to make connections that would not normally occur while completing problem sets. These projects follow the typical sequence of a 7th/8th grade Pre-Algebra course. The major concepts covered will be integers, equations, factors and fractions, rational numbers, ratios, proportions, percents, inequalities, functions, graphing, right triangles, and two-dimensional figures. These projects are to be used in conjunction with a standard Pre-Algebra curriculum.

MA.7.NS.2.3: Mathematics

Multiply, divide, and simplify rational numbers by using exponent rules.

MA.7.NS.2.4: Mathematics

MA.7.NS.2.5: Mathematics

Understand the meaning of the absolute value of a number; interpret the absolute value as the distance of the number from zero on a number line; and determine the absolute value of real numbers.

MA.7.AF.1.1: Mathematics

Use variables and appropriate operations to write an expression, an equation, an inequality, or a system of equations or inequalities that represents a verbal description (e.g., three less than a number, half as large as area A).

MA.7.AF.1.2: Mathematics

Use the correct order of operations to evaluate algebraic expressions such as 3(2x + 5)².

MA.7.AF.1.3: Mathematics

Simplify numerical expressions by applying properties of rational numbers (e.g., identity, inverse, distributive, associative, commutative) and justify the process used.

MA.7.AF.1.5: Mathematics

Represent quantitative relationships graphically and interpret the meaning of a specific part of a graph in the situation represented by the graph.

MA.7.AF.2.1: Mathematics

Interpret positive whole-number powers as repeated multiplication and negative whole-number powers as repeated division or multiplication by the multiplicative inverse. Simplify and evaluate expressions that include exponents.

MA.7.AF.2.2: Mathematics

Multiply and divide monomials; extend the process of taking powers and extracting roots to monomials when the latter results in a monomial with an integer exponent.

MA.7.AF.3.3: Mathematics

Graph linear functions, noting that the vertical change (change in y-value) per unit of horizontal change (change in x-value) is always the same and know that the ratio ("rise over run") is called the slope of a graph.

MA.7.AF.3.4: Mathematics

Plot the values of quantities whose ratios are always the same (e.g., cost to the number of an item, feet to inches, circumference to diameter of a circle). Fit a line to the plot and understand that the slope of the line equals the quantities.

MA.7.AF.4.1: Mathematics

Solve two-step linear equations and inequalities in one variable over the rational numbers, interpret the solution or solutions in the context from which they arose, and verify the reasonableness of the results.

Solve multistep problems involving rate, average speed, distance, and time or a direct variation.

MA.7.MG.1.1: Mathematics

Compare weights, capacities, geometric measures, times, and temperatures within and between measurement systems (e.g., miles per hour and feet per second, cubic inches to cubic centimeters).

MA.7.MG.1.2: Mathematics

Construct and read drawings and models made to scale.

MA.7.MG.1.3: Mathematics

Use measures expressed as rates (e.g., speed, density) and measures expressed as products (e.g., person-days) to solve problems; check the units of the solutions; and use dimensional analysis to check the reasonableness of the answer.

MA.7.MG.2.2: Mathematics

Estimate and compute the area of more complex or irregular two- and three-dimensional figures by breaking the figures down into more basic geometric objects.

MA.7.MG.2.3: Mathematics

Compute the length of the perimeter, the surface area of the faces, and the volume of a three-dimensional object built from rectangular solids. Understand that when the lengths of all dimensions are multiplied by a scale factor, the surface area is multiplied by the square of the scale factor and the volume is multiplied by the cube of the scale factor.

MA.7.MG.3.1: Mathematics

Identify and construct basic elements of geometric figures (e.g., altitudes, mid-points, diagonals, angle bisectors, and perpendicular bisectors; central angles, radii, diameters, and chords of circles) by using a compass and straightedge.

MA.7.MG.3.2: Mathematics

Understand and use coordinate graphs to plot simple figures, determine lengths and areas related to them, and determine their image under translations and reflections.

MA.7.MG.3.3: Mathematics

Reviewer Comments:

This unit consists of games to accompany a 7th-8th grade pre-algebra course. The teacher will devote one class period every unit to games, which reinforce the topic of the unit and provide some fun for the students. The games are typically group rather than individual activities, rewarding collaboration rather than personal knowledge. This is how it should be.
