Khan Academy Practice solving word problems involving ratios.
Sec. 4.2 – More Ratios & Rates – Part 2
Khan Academy Practice solving more word problems involving ratios and rates.
Sec. 4.2 – More Ratios & Rates – Writing Proportions
Khan Academy Practice setting up proportions BEFORE using “magic circle,” “Y-thingy-thingy,” or logic to solve for the unknown.
Sec. 4.2 – More Ratios & Rates – Solving Proportions
Khan Academy Practice solving proportions using ”magic circle,” “Y-thingy-thingy,” or logic to solve for the unknown.
Unit 5 – Linear Relations
Sec. 5.3 – Rates of Change (Finding the Slope of a Line)
Khan Academy Practice finding the rate of change (also known as “Slope”) of a linear relation
Sec. 5.4 – More Rates of Change (Finding the Slope of a Line)
Khan Academy Practice finding the rate of change for real world scenarios

Unit 8 – Plane Geometry
Angles in Triangles – Angle Types
Khan Academy Practice your skills at identifying acute, obtuse, and right angles
Angles in Triangles – Triangle Types
Khan Academy Practice identifying whether triangles are equilateral, isosceles, or scalene
Angles in Triangles – Find Angles
Khan Academy Practice determining the missing angle in each triangle
Angles in Triangles – Complementary & Supplementary
Khan Academy Practice using your knowledge of complementary and supplementary angles
Angle Relationships – F, Z, C Patterns
Khan Academy Practice using your knowledge of F, Z, & C Patterns
Angle Relationships – Solve for Unknown
Khan Academy Practice connecting algebra to geometry. Use geometric relationships to solve for an unknown variable.
Angle Relationships – More Difficult 1
Khan Academy Practice more difficult problems which require a firm understanding of different geometric relationships
Angle Relationships – More Difficult 2
Angle Relationships – Polygons
Khan Academy Practice sum of interior angles of a polygon. Recall that a triangle has 180 degrees, quadrilateral has 360 degrees, and for each side you add after that, add 180 degrees. In other words, split your shape into triangles and multiply the number of triangles by 180 degrees.
