Identify types of lines and angles. Classify two-dimensional figures in a hierarchy based on properties.
 Week 2
Lesson 3
Area & perimeter of polygons
Identify and calculate the area and perimeter of figures and use them to solve real-world and mathematical problems.
Lesson 4
Area & perimeter of compound shapes 
Identify and calculate the area and perimeter of figures and use them to solve real-world and mathematical problems.
 Week 3
Lesson 5
Measure angles
Solve real-world problems using angle measurements. Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
Lesson 6
Circles
Identify parts of the circle. Calculate the area and circumference of circles and use them to solve real-world and mathematical problems.
 Week 4
Lesson 7
Similar figures
Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale. 
Lesson 8
Triangle inequality theorem
Prove whether three lines could make a triangle using the triangle inequality theorem. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
 Week 5
Lesson 9
Polygons on the coordinate plane
Answer questions about polygons based on ordered pairs on the coordinate plane. 
Lesson 10
Transformations
Identify and use the four transformations on the coordinate plane.
