1. The document provides materials for teaching geometry concepts like perimeter and area to students. It includes 10 lessons with objectives, activities, and worksheets. 2. The lessons have the students identify and compare squares and rectangles, measure the sides of objects to calculate perimeter and area, and do a group project measuring and calculating values for rooms in their school. 3. The materials include assessments to evaluate student understanding of perimeter, area, and applying these concepts to real-world examples.

Session 5 - Worksheet 5
Group Project: A Room at School
At school we want to renovate the floor and put down new tiles and a new
baseboard.
TILES BASEBOARD
We have 8 equal size classrooms, a computer room, a music classroom, a
support classroom, an English classroom, a staff room and the boys’ toilets
and girls’ toilets.
Each group is in charge of measuring one of these rooms. Two students will
be in charge of measuring and the third student has to note the
measurements down.
Your group has assigned the room:
.............................................................................................................................
Tasks:
1. Your group has to show a drawing of the room with the measurements.
2. Your group has to calculate the area and the perimeter of your assigned
room.
3. Your group has to say how many square meters of tiles are needed and
how many meters of baseboard are needed.
4. Finally, your group has to share the information with the rest of the class by
a poster.
