Day 3: Concept Modeling Foundations

Daily Learning Contract

• Topic: Career Opportunities
• Objective: Students will identify how an Architecture & Construction worker uses top and front views and create a two-view concept with five spatial-design operations.
• TEKS: d(1)(C)
• Demonstration of Learning: Two-view concept, first design checkpoint, and career-role work-product explanation.

Lesson Overview

Before Class

• Default: one device per student, one projector, and zero prints. Open the four-page concept packet and private Canvas annotation route. Paper: one packet, one pencil, and one ruler per student, plus one collection tray per class.
• If using the optional Tinkercad extension, confirm district approval, create a teacher-managed Classroom with Safe Mode on, and test the class-code/nickname route, WebGL, saving, and concurrent Chromebook use.
• Put any tested live class code in the teacher's local course copy. The master course does not promise reusable class codes, screenshots, or controls.

Tinkercad introduces spatial modeling and iterative design. It is not the same as professional Revit/AutoCAD documentation, code review, or structural analysis.

50-Minute Flow

1. Read the brief — 5 minutes

The fictional client needs a small community learning space with four exterior walls, a roof, one entrance, two windows, and one purposeful feature. This is a concept/massing model, not a construction-ready design.

2. Choose the build surface - 5 minutes

Students open Canvas annotation or paper. If the teacher has opened a tested Tinkercad Classroom, students may join by class code and nickname. Do not improvise individual Google or Autodesk account creation.

3. Guided five-skill build — 15 minutes

Model drag/place, resize, align, group, and hole/subtract one at a time. After each operation, students reproduce it in the starter model or mark the equivalent step on paper. The supplied top/front-view example is the no-prep projection model.

4. Sketch and begin — 20 minutes

Students complete:

• a top-down view on a grid at least 7.5 × 5 inches;
• a front view at least 7.5 × 4 inches;
• labels for use, entrance, windows, roof, and one feature;
• one sentence explaining who uses the space and why one design choice helps.

Then students begin the concept. The Day 3 checkpoint is a complete top and front view, or, when Tinkercad is enabled, a saved model with the main footprint and exterior walls.

5. Exit — 5 minutes

Name one Architecture & Construction worker who would use or interpret a more advanced version of this design, and state what that worker would produce or decide.

Supports and Absence Route

Canvas annotation and paper are complete routes. Students may use ruler/grid paper, enlarged print, keyboard entry, speech-to-text, or a teacher-provided starter. Tool speed and artistic polish are not graded.

At minute 8, ask students what top and front views show differently. At minute 15, every student needs a working surface and footprint; move immediately to paper after a failed join. Check orientation and labels during minutes 18-25 and the purposeful feature/user need during minutes 30-38. Trim the fifth operation demonstration, not the two views, checkpoint, career-role exit, or collection.
