## 7.G.1-7.G.3

Draw, Construct, And Describe Geometrical Figures And Describe The Relationships Between Them.

7.G.1 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.
7.G.2 Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. 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.
7.G.3 Describe the two-dimensional figures that result from slicing three- dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.

### Geometric Shapes

Through the use of virtual manipulatives, games, and practice problems students will solve problems involving scale drawings of geometric shapes.  Basic Mathematics Scale Drawings - This is an informative page about scale drawings.  Students will most likely need support when reading ...

### Super Scale Drawings

The purpose/focus of this playlist is to review scale drawings.Students review how to set up similar figure proportions in Similar Figures, and then practice solving problems in Perimeter, Area, and Volume Changes in Scale (IXL). Next, students review how to make a scale drawing themselves in How to...
