Free Printable Enlargement Worksheets for Class 7

Begin with a shape on a coordinate grid and enlarge it from a clear center using an integer scale factor. Have students compare corresponding side lengths and angles, then connect their observations to the rule: lengths are multiplied by the scale factor, while angle measures stay the same.

Use a progression of three tasks: enlarge figures on coordinate grids, find missing lengths in similar figures, and work backward to determine a scale factor. Include problems with different centers of enlargement so students learn to track the relationship between each point and its image.

Students may add the scale factor instead of multiplying, measure from the origin rather than the stated center of enlargement, or change angles while redrawing the figure. A quick check is to confirm that corresponding sides have one consistent ratio and corresponding angles remain equal.

Common Core develops this idea through scale drawings and proportional relationships in Grade 7. Students use a scale factor to calculate corresponding lengths and areas, building the foundation for the more formal study of dilations and similarity in Grade 8.

Give students who struggle with dense diagrams a large-print or wide-spaced version, and use extended time for learners who need longer to plot and verify coordinates. Advanced students can work backward from an image to identify the center and scale factor.

Enlargement is commonly introduced in Grade 7 through scale drawings, similar figures, and proportional side lengths. The concept becomes more formal in Grade 8, when students study dilations as geometric transformations.
