LENGTH AND PERIMETER
BIG IDEAS:
(taken from “Big Ideas by Dr. Small”):
- There is always value in estimating a measurement.
- The length of an object is a one-dimensional attribute. Length can be the measurement of a single measure of an object or a combined linear measure, like perimeter.
STUDENT LEARNING GOALS:
GOAL: I can convert metric units between kilometres, metres, centimetres and millimetres.
- QUIZ: Metric Relationships (converting units)
- VIDEO: Metric Conversion (this is not a Khan video but does outline some algorithms around metric conversions)
- GAME: Metric Matching
- GAME: Metric System Rockets
- GAME: Metric Measurement Millionaire
GOAL: I can use a ruler to measure to nearest tenth of centimeter (i.e. mm).
- QUIZ: Measuring Lengths
- QUIZ: Measuring Perimeter
- QUIZ: Perimeter of Rectangles
- VIDEO: Comparing Lengths (1 video, 1 practice quiz)
- VIDEO: Estimating Lengths (1 video, 1 practice quiz)
- VIDEO: Measurement Word Problems (1 video, 1 practice quiz)
CURRICULUM EXPECTATIONS:
- select and justify the most appropriate standard unit (i.e., millimetre, centimetre, decimetre, metre, kilometre) to measure length, height, width, and distance;
- solve problems requiring conversion from metres to centimetres and from kilometres to metres (Sample problem: Describe the multiplicative relationship between the number of centimetres and the number of metres that represent a length. Use this relationship to convert 5.1 m to centimetres.);
