Part of Unit: Geometry
Lesson Plan Overview / Details
Students will learn how to draw triangles (equilateral and
acute) in SketchUp. Student will produce a drawing in sketchup of a
2 different triangular prisms (equilateral and acute base) of a
given area of base and volume.

Activities in this Lesson
- Introduction - Hooks / Set
On a half sheet of paper, student will be asked to draw a 3 different looking triangles (not different sized triangles),describe a triangle in their own words and locate a triangle in the
classroom (describe, identify and locate in the classroom) or they could describe where one can find triangle outside the classroom. - Lecture - Lecture
Teacher draws a equilateral triangle and describe/lists its properties (equal sides and 60° angle corners).
Teacher draws a isosceles triangle and describe/list its properties (two congruent legs and two congruent base angles).
Teacher draws a acute triangle and describe/list its properties (all acute angles - angle less than 90°).
Teacher draws a Scalene triangle and describe/list its properties (no sides congruent).
Teacher draws an Obtuse triangle and describe/list its properties (one obtuse angle - bigger than 90°).
Teacher draws a Right triangle and describe/list its properties (one right angle - 90°). - Drawing Triangles in SketchUp - Demo / Modeling
Teacher will demonstrate how to draw a the 6 different triangles using the line tool.
Teacher will demonstrate how to draw an equilateral triangle using the polygon tool.
Teacher will demonstrate how to put dimensions/measurements in
their drawing (using the dimension tool) to verify the shape of their
drawing. - Activity 2A: My triangles - Lab / Shop
Students will draw the 6 different triangles in sketchup.
They will put dimension/measurements to verify their shapes. - Triangular Prisms - Demo / Modeling
Teacher will demonstrate how to create triangular prisms using the push/pull tool (with keyboard input).
Teacher will re-demonstrate how to put dimensions/measurements in sketchup. - Activity 2B: My Cube and Rectangular Prism - Lab / Shop
Students will use the push/pull tool to convert their triangles into triangular prisms.
- Area, Perimeter, Surface area and volume - Lecture
Teacher will demonstrate how to calculate base area, surface area and volume of cubes and prisms.
- Triangle [ Go to Site ]
- Triangle_area [ Go to Site ]
- Volume [ Go to Site ]
- Activity 2C: My object calculations - Lab / Shop
Students will calculate their objects base area, base perimeter and
volume on a whole sheet of paper. They will need to include a freehand
diagram of their object with measurements. Teacher will demonstrate how to find the measures of an object with a
given requirement of a base area and a given requirement for a volume.- Closure - Assessment
Teacher will ask students to write down their date of birth (month,day and year)
Teacher will ask students to multiply their birth day (not the
birth year) with 100 and this will be their base area requirement for a
prism with an equilateral triangle base
Teacher will ask students to multiply their birth day (not the
birth year) with 150 and this will be their base area requirement for another triangular prism.
Teacher will ask students to multiply their birth day and their
birth year and this will be their volume requirement for their both triangular prisms.
Teacher will tell Students that there will be a test (tomorrow if no time today) based on these requirements.- Skyscraper lesson 2 test.docx [ Download ]
