Geometry & Building Trades:A Blended ApproachSteve Olson & Jason DahlOconomowoc High School
Our goals for today:● Show our approach to combining a geometry and
carpentry class● Share some successes and struggles in our format● Show examples of project based assessments● Walk through an sample assessment for a unit
About usSteve Olson● Taught at OHS for 20 yrs● Classes also taught:
○ Building Trades I, II, and III
● Athletics:○ Wrestling, Softball
● Advisor to Construction Club
Jason Dahl● Taught at OHS for 7 yrs● Classes also taught:
○ Algebra, Geometry, and AP Statistics
● Athletics○ Boys & Girls Golf
From the ground up...● 2 credit class: Geometry
& Building Trades● 2 regular education
teachers (Math & T. Ed)● Block schedule - every
day for 90 min○ Whole group○ Small group (2 groups of 20
or 4 groups of 10)
How many students?● Class Sizes
○ 2012-13: 48○ 2013-14: 22○ 2014-15: 42○ 2015-16: 40?
Class Content & LayoutGeometry Units:1: Building Blocks of Geometry 2: Transformations (& Similarity)3. Trigonometry (& Similarity)4. Volume 5. Quadrilaterals6. Triangles (Proofs)7. Circles

Unit 2: Transformations, Materials & Lumber
Summative Project: Miniature Golf Hole● End Goal: To create multiple hole-in-one routes with 12 square feet
of OSB○ Geometry Concepts:
■ Reflections, Similarity, Surface Area○ Building Trades Concepts:
■ Accurately use power tools, measure and layout hole■ Reuse salvaged lumber effectively, perspective views
● Students make a design on ¼ grid paper, miniature model, and actual scale model (Paper: ¼” = 2”, Model: 1:4)
Unit 2: Transformations, Materials & Lumber
We’re going to give you a chance to create a mini golf hole!
