Free Printable Enlargement Worksheets for Class 8

Model enlargement as a dilation: draw rays from the center of enlargement through each vertex, then place each image point at a distance multiplied by the scale factor. Ask students to explain why corresponding angles stay equal even though side lengths change.

Combine coordinate-grid dilations, missing-length problems, and tasks that require students to calculate the scale factor from two corresponding sides. Once students are secure, give them an original figure and its image and ask them to locate the center of enlargement.

Look for students using inconsistent scale factors across corresponding sides, confusing the center of enlargement with the origin, or reversing the ratio when calculating the scale factor. Another common error is assuming area changes by the scale factor rather than by its square.

Teachers can host the worksheet as a digital quiz on Wayground or print the PDF and assign it on paper. Every worksheet has a complete answer key, and paper submissions can be scanned or captured for grading in the Wayground for Teachers app.

Common Core treats enlargement as dilation within transformation geometry. Students build from Grade 7 scale drawings toward describing how a dilation changes coordinates and lengths, then use those relationships to establish similarity between figures.

Use a large-font, wide-spaced worksheet so coordinates and grid labels are easier to track. In a digital session, extended time can help students plot carefully, while reduced answer choices can make scale-factor questions more manageable without changing the underlying skill.

Enlargement is typically developed across Grades 7 and 8. Grade 7 emphasizes scale drawings and proportional lengths; Grade 8 formalizes the concept through dilations, centers of enlargement, coordinates, and similarity.
