9 units ยท printable worksheets, answer guides & syllabus.
The full unit-by-unit outline (unit goals, section goals, lesson list).
Each unit has a student worksheet and a parent/teacher answer guide.
Students study scaled copies of plane figures and scale drawings of real-world objects, learning that lengths in a scaled copy are products of the original lengths and a scale factor while angles are preserved.
Students develop the idea of a proportional relationship, working with relationships represented in tables, as equations, and on graphs.
Students apply their knowledge of proportional relationships to measuring circles, learning the relationships between radius, diameter, circumference, and area.
Students deepen their understanding of proportional relationships and percentages, solving multi-step problems and working with situations that involve fractional amounts.
Students perform operations on rational numbers, which are all numbers that can be written as a positive or negative fraction.
Students deepen their algebraic reasoning as they write and solve equations and inequalities, and work with more complex equivalent expressions.
Students investigate angle relationships, conditions for unique triangles, and the area, surface area, and volume of prisms.
Students work with probability and sampling, designing simulations, representing sample spaces, and using samples to make inferences about populations.
Students use concepts and skills from previous units to solve problems in the contexts of running a restaurant, making connections across topics, and designing a course.
