I can find unknown angle measures by reasoning about adjacent angles with known measures.
I can recognize when an angle measures $90^\circ$, $180^\circ$, or $360^\circ$.
Lesson 2: Adjacent Angles
I can recognize when adjacent angles are complementary or supplementary.
I can find unknown angle measures by reasoning about complementary or supplementary angles.
Lesson 3: Nonadjacent Angles
I can determine if angles that are not adjacent are complementary or supplementary.
I can explain what vertical angles are in my own words.
Lesson 4: Solving for Unknown Angles
I can reason through multiple steps to find unknown angle measures.
I can recognize when an equation represents a relationship between angle measures.
Lesson 5: Using Equations to Solve for Unknown Angles
I can write an equation to represent a relationship between angle measures and solve the equation to find unknown angle measures.
Lesson 6: Building Polygons (Part 1)
I can show that the 4 side lengths that form a quadrilateral can be rearranged to form different quadrilaterals.
I can show that the 3 side lengths that form a triangle cannot be rearranged to form a different triangle.
Lesson 7: Building Polygons (Part 2)
I can show whether or not 3 side lengths will make a triangle.
I can reason about a figure with an unknown angle.
Lesson 8: Triangles with 3 Common Measures
I understand that changing which sides and angles are next to each other can make different triangles.
Lesson 9: Drawing Triangles (Part 1)
Given two angle measures and one side length, I can draw different triangles with these measurements or show that these measurements determine one unique triangle or no triangle.
Lesson 10: Drawing Triangles (Part 2)
Given two side lengths and one angle measure, I can draw different triangles with these measurements or show that these measurements determine one unique triangle or no triangle.
Lesson 11: Slicing Solids
I can picture different cross sections of prisms and pyramids.
I can explain that when a three dimensional figure is sliced it creates a face that is two dimensional.
Lesson 12: Volume of Right Prisms
I can explain why the volume of a prism can be found by multiplying the area of the base and the height of the prism.
Lesson 13: Decomposing Bases for Area
I can calculate the the volume of a prism with a complicated base by decomposing the base into quadrilaterals or triangles.
Lesson 14: Surface Area of Right Prisms
I can picture the net of a prism to help me calculate its surface area.
I can find and use shortcuts when calculating the surface area of a prism.
Lesson 15: Distinguishing Volume and Surface Area
I can decide whether I need to find the surface area or volume when solving a problem about a real-world situation.
Lesson 16: Applying Volume and Surface Area
I can solve problems involving the volume and surface area of children’s play structures.
