Common Core For Grade 3
Videos, examples, solutions, and lessons to help Grade 3 students learn to recognize area as an attribute of plane figures and understand concepts of area measurement.
A. A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.
B. A plane figure which can be covered without gaps or overlaps by n
unit squares is said to have an area of n
Common Core: 3.MD.5
Suggested Learning Targets
3.MD.5.a - The Square Unit (Area)
- I can define a unit square.
- I can define area as the measure of space within a plane figure and explain why area is measured in square units.
This video explains the concept behind area, which focuses on the unit square. This illustrates 3.MD.5.a in the grade 3 Common Core Standards for Mathematics.
3.MD.5.b - Cover a Plane Figure with Square Units (Area)
This video explains how to find the area of a plane (flat) figure by covering it with square units. This is the basic process behind finding the area of a plane figure, which illustrates 3.MD.5.b in the grade 3 Common Core Standards for Mathematics.
