Interface Exploration

Overview

In this lesson 3 of 15, students learn how to navigate the OnShape interface so they can reliably use tools and the workspace during later CAD construction tasks. Students connect their actions (what they did, why it worked, what changed) to geometric reasoning and precise tool use.

Learning intentions

Students will be able to:

• Identify and explain the purpose of key OnShape interface areas (workspace, toolbars, panels).
• Navigate views in OnShape (rotate, zoom, pan) accurately and safely.
• Use common interface controls to create, select, and edit with fewer errors.
• Describe the steps of an interface workflow clearly enough that a classmate can repeat it.

Success criteria

I can…

• Name at least 4 parts of the OnShape interface and state what each helps me do.
• Change my view to clearly see a selected object without losing my place.
• Follow a short on-screen “procedure” and match my results to the target outcome.
• Write or record a clear, organized set of steps using headings or numbered order.

Curriculum links

• Technology integration using tools appropriately (ruler/protractor analog replaced by OnShape tools) aligns with the practice of choosing and using tools strategically.
• When students later construct triangles in CAD from given measures, they will draw on geometric construction expectations from grade 7 geometry standards.
• Students organize writing for step-by-step procedures, using an introduced topic and clear organization, supported by formatting.
• Students can use technology to produce and publish short writing and include references/citations if required by the unit norms.

Lesson structure (45 minutes)

1. 0–5 min · Quick hook (Think–Pair–Share). Teacher displays a screenshot of OnShape with several labeled regions covered; students discuss what each labeled area might control and why that matters.

2. 5–12 min · Mini demo: “Find it, name it, use it.” Teacher demonstrates OnShape navigation and labels: workspace, left/top tool/feature areas, and any navigation controls; students repeat by verbally naming what each area does.

3. 12–22 min · Guided practice: view navigation challenge. Teacher gives three tasks: (a) rotate to see an object clearly, (b) zoom to read details, (c) pan to reposition view—one at a time. Students complete each task and stop to check: “Did I keep the selection/object in view?”

4. 22–33 min · Skill stations: interface operations (2 rounds). Teacher sets up two short station cards students rotate through:

• Station A: selection and focus (select parts/edges correctly, clear selections, reselect).
• Station B: tool workflow and panel use (open the right tool/command area, adjust settings, apply/commit). Students record station outcomes in a brief checklist: task done, time, and one common mistake to avoid next time.

5. 33–42 min · Procedure writing (structured steps). Students write a short “How to navigate OnShape” procedure using formatting: a heading and 4–6 numbered steps (example: Step 1: rotate… Step 2: zoom…). Teacher reminds them to organize ideas clearly and introduce the topic first.

6. 42–45 min · Exit ticket (1 question + 1 self-check). Students submit: “Which interface area controls view navigation, and what is one action you can do there?” plus a quick self-rating (Confident / Not yet) for view navigation.

Resources

• Devices with OnShape access for all students
• Teacher demo slides or screenshots (no student logins shown publicly)
• Printed “Station Cards” for Station A and Station B
• Student interface checklist handout (name parts + navigation tasks)
• Writing paper or digital document template with heading and numbered steps
• Timer for station rotations

Assessment

• Teacher observation during guided practice: students successfully rotate/zoom/pan without losing selection or orientation
• Station checklist review: whether students complete tasks and identify one likely mistake
• Exit ticket: correct identification of the navigation controls and a meaningful action description
• Quick scan of procedure writing for clear organization (heading + numbered steps) and accuracy of the steps

Differentiation

• Support: Provide sentence starters for procedure writing (e.g., “First, I will… Next, I will…”), and show a “model” procedure with partially filled steps.
• Support: Offer a color-coded or icon-only checklist so students can match actions to UI elements quickly.
• Extension: Students who finish early can write an additional “Troubleshooting” step (e.g., what to do if the view is blocked or selection won’t stick).
• EAL/SEN: Allow students to complete their procedure steps using short phrases, diagrams, or voice-to-text if permitted; clarify vocabulary by acting it out during demos (rotate, zoom, pan, select).

Alignment note (how this prepares future CAD construction)

Students’ precision with navigation and interface controls in this lesson supports later OnShape tasks where they will construct and verify geometric figures from given conditions. Clear, organized step-writing also prepares them to document construction workflows and check for accuracy, which will be essential in the unit’s upcoming triangle and measure-based activities.
