Grade 7 Accelerated: Geometry and Measurement

Construct and describe geometrical figures, analyzing relationships among them.

7A.33

Partially covered
Solve problems involving scale drawings of geometric figures including computation of actual lengths and areas from a scale drawing and reproduction of a scale drawing at a different scale. [Grade 7, 17]

7A.34

Mostly covered
Construct geometric shapes (freehand, using a ruler and a protractor, and using technology) given measurement constraints with an emphasis 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. [Grade 7, 18]

7A.35

Fully covered
Describe the two-dimensional figures created by slicing three-dimensional figures into plane sections. [Grade 7, 19]

Solve real-world and mathematical problems involving angle measure, area, surface area, and volume.

7A.36

Explain the relationships among circumference, diameter, area, and radius of a circle to demonstrate understanding of formulas for the area and circumference of a circle.

7A.36.a

Mostly covered
Informally derive the formula for area of a circle.

7A.36.b

Mostly covered
Solve area and circumference problems in real-world and mathematical situations involving circles. [Grade 7, 20]

7A.37

Fully covered
Use facts about supplementary, complementary, vertical, and adjacent angles in multi-step problems to write and solve simple equations for an unknown angle in a figure. [Grade 7, 21]

7A.38

Analyze and apply properties of parallel lines cut by a transversal to determine missing angle measures.

7A.38.a

Fully covered
Use informal arguments to establish that the sum of the interior angles of a triangle is 180 degrees. [Grade 8, 25]

7A.39

Fully covered
Solve real-world and mathematical problems involving area, volume, and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right rectangular prisms. [Grade 7, 22]

7A.40

Mostly covered
Informally derive the formulas for the volume of cones and spheres by experimentally comparing the volumes of cones and spheres with the same radius and height to a cylinder with the same dimensions. [Grade 8, 29]

7A.41

Mostly covered
Use formulas to calculate the volumes of three-dimensional figures to solve real-world problems. [Grade 8, 30]

Understand congruence and similarity using physical models or technology.

7A.42

Verify experimentally the properties of rigid motions (rotations, reflections, and translations): lines are taken to lines, and line segments are taken to line segments of the same length; angles are taken to angles of the same measure; and parallel lines are taken to parallel lines.

7A.42.a

Not covered
Given a pair of two-dimensional figures, determine if a series of rigid motions maps one figure onto the other, recognizing that if such a sequence exists the figures are congruent; describe the transformation sequence that verifies a congruence relationship. [Grade 8, 22]

7A.43

Not covered
Use coordinates to describe the effect of transformations (dilations, translations, rotations, and reflections) on two-dimensional figures. [Grade 8, 23]
(Content unavailable)

7A.44

Not covered
Given a pair of two-dimensional figures, determine if a series of dilations and rigid motions maps one figure onto the other, recognizing that if such a sequence exists the figures are similar; describe the transformation sequence that exhibits the similarity between them. [Grade 8, 24]
