In Measurement We Are Learning About...
Estimation
Conversion
Perimeter
Area
Surface Area
Volume
Do you know what any of these words mean?
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 reallife 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.);
Activate  Perimeter
Remember in Canada we use the Metric System  MM, CM, M, KM (Not Miles or Inches)
Perimeter  Hands On
Use the shapes to make a geometric design  Choose 3 shapes from your geometric design to measure  Must choose a triangle and a parallelogram to measure  you choose the third shape to measure

Area  Square, Rectangle, Triangle  Math Antics
This task consists of three parts.
 You will make a geometric design using the following shapes: triangles, parallelograms, hexagons, trapezoids, rectangles, squares. Be creative!
 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.
 Measure your three shapes and record the perimeter and area for each. Show all work.

Area of a Triangle
What is the formula to calculate the area of a square or rectangle?
How would you make the metre squared you built in class into 2 equal triangles?
What is the area of one of the triangles? How do you know?
Can you think of a formula to represent that?
