2D & 3D Measurement

Overall Learning Goals

• estimate, measure, and record quantities, using the metric measurement system;
• determine the relationships among units and measurable attributes, including the area of a parallelogram, the area of a triangle, and the volume of a triangular prism.

Lesson Goals - Linear Measurement

• demonstrate an understanding of the relationship between estimated and precise measurements, and determine and justify when each kind is appropriate (Sample problem:You are asked how long it takes you to travel a given distance. How is the method you use to determine the time related to the precision of the measurement?);
• estimate, measure, and record length, area, mass, capacity, and volume, using the metric measurement system.

Big Ideas In Measurement

The Big Ideas of Measurement in Grades 4 to 6

• investigate measurement problems in real-life settings;

• extend their knowledge of measurement units and their relationships;

• investigate the relationships between, and develop formulas for, area and perimeter and surface area and volume;

• extend their knowledge of time and temperature measurement.

Perimeter and Area

• construct a rectangle, a square, a triangle, and a parallelogram, using a variety of tools (e.g., concrete materials, geoboard, dynamic geometry software, grid paper), given the area and/or perimeter (Sample problem: Create two different triangles with an area of 12 square units, using a geoboard.);

Remember in Canada we use the Metric System - MM, CM, M, KM (Not Miles or Inches)

This task consists of three parts.

1. You will make a geometric design using the following shapes: triangles, parallelograms, hexagons, trapezoids, rectangles, squares. Be creative!

2. Choose three of the shapes to measure - one must be a triangle and one must be a parallelogram; you may choose the third shape. Identify the shapes you have chosen by labelling them 1, 2, 3.

3. Measure your three shapes and record the perimeter and area for each. Show all work.
