## 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: 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 metric unit (i.e., millimetre, centimetre, decimetre, metre, decametre, kilometre) to measure length or distance in a given real-life situation.
- Solve problems requiring conversion from larger to smaller metric units (eg., metres to centimetres, kilograms to grams, litres to millilitres)
## AREA, Surface Area, PERIMETER AND VOLUME

UNIT:Area and VolumeBIG IDEAS(taken from “Big Ideas by Dr. Small”):

- 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.

- The area of an object is a two-dimensional attribute. Area can be a single measure of a 2-D shape on an object or a combined measure of a 3-D shape, like surface area.
- The volume of a 3-D object tells how much material it takes to build the object and the capacity of an object tells how much it will hold.
STUDENT LEARNING GOALS:

- I can determine the area and perimeter of a rectangle
- I can create a rectangle given the area and/or perimeter
- I can determine the volume of a rectangular prism.
CURRICULUM EXPECTATIONS:

- construct a rectangle, a square, a triangle, and a parallelogram using a variety of tools, given the area and/or perimeter.
- determine, through investigation, the relationship between the area of a rectangle and the areas of parallelograms and triangles, by decomposing and composing
- develop the formulas for the area of a parallelogram and the area of a triangle
- solve problems involving the estimation and calculation of the areas of triangles and the areas of parallelograms
- determine, using concrete materials, the relationship between units use to measure area and apply the relationship to solve problems that involve conversions from square metres to square centimetres.
- determine, through investigation using a variety of tools and strategies, the relationship between the height, the area of the base, and the volume of a triangular prism and generalize to develop the formula.
- determine through investigation using a variety of tools and strategies, the surface area of a rectangular and triangular prisms.
- Solve problems involving the estimation and calculation of the surface area and volume of triangular and rectangular prisms.
