In this learning and evaluation situation, secondary III students will simulate some of the steps involved in a bedroom renovation project. Working within the defined constraints, students will choose and cut out furniture and accessories for their room, then arrange and glue them on a floor plan. This floor plan will then be used as a jumping-off point for students to acquire new knowledge relating to scales and dimensioning. At the end of the LES, each student will hand in their Student Booklet and a dimensioned floor plan. The assessment can be summative or formative at the teacher’s discretion.
The following objectives are addressed during the LES.
* Objectives marked with an asterisk may have been covered in Sec. I or Sec. II.
