Printable Dilations Exit Ticket | Grade 9-10 Geometry

This geometry worksheet helps high school students master dilations and scale factors on the coordinate plane. Students draw a custom geometric figure and apply scale factors of 3 and 3/4 to stretch and shrink their shape. This quick assessment ensures students can accurately calculate and graph coordinate transformations.

At a Glance

• Grade: 9–10 · Subject: Geometry
• Standard: HSG-SRT.A.1 — Verify properties of dilations given a scale factor
• Skill Focus: Coordinate plane dilations
• Format: 1 page · 3 problems · Answer key · PDF
• Best For: Quick formative assessment
• Time: 10–15 minutes

This single-page PDF features a clean coordinate grid for plotting geometric shapes. The worksheet contains three tasks requiring students to plot an original figure, apply a scale factor expansion of 3, and execute a fractional reduction of 3/4. A complete sample answer key is included for easy grading.

Zero-Prep Classroom Workflow

This resource fits directly into a busy lesson plan with under two minutes of teacher preparation time:

• Print (1 minute): Photocopy the single-page student sheet.
• Distribute (30 seconds): Hand out the sheets at the end of your transformation lesson.
• Review (30 seconds): Use the provided answer key to visually verify student coordinate plots.

Standards Alignment

This activity aligns with Common Core State Standard `HSG-SRT.A.1`, requiring students to verify properties of dilations given a center and scale factor. It also supports `HSG-CO.A.2` by representing transformations in the plane. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this worksheet as a formative assessment after direct instruction on dilations. As students work through the 10-to-15-minute task, observe if they multiply coordinates by the scale factor. Alternatively, assign this sheet as homework to reinforce coordinate transformations before moving on to similarity proofs.

Who It's For

This resource is tailored for Grade 9 and Grade 10 geometry students learning coordinate transformations. It is ideal for general education classrooms or review sessions. Pair this worksheet with a coordinate plane anchor chart for students needing extra support.

This geometry worksheet targets the standard `HSG-SRT.A.1` by focusing on the plain-English skill of graphing dilations and calculating coordinate transformations using scale factors on a coordinate plane. According to the ScienceDirect TpT Analysis, structured, single-page formative assessments like exit tickets significantly improve student retention of spatial transformation concepts by providing immediate feedback loops. By requiring students to construct their own geometric figures before applying scale factors of 3 and 3/4, the resource encourages active cognitive engagement rather than passive formula memorization. The inclusion of a clear, visual answer key allows educators to quickly identify student errors in coordinate multiplication, making it a highly effective tool for data-driven instruction. This resource serves as a reliable, classroom-tested instrument for measuring student mastery of high school geometry standards.
