Finding the Area of a Rectangle or Square: Counting Square Units

This lesson teaches how to find the area of a square or rectangle by counting square units. It explains the concept of area as the space within a shape, differentiates it from perimeter, and demonstrates how to use square tiles to measure area. An example is provided where the area of a rectangle is calculated by counting the number of square tiles that fit inside it, emphasizing that each tile represents one square unit.

What is the area of a shape?

• The distance around the shape

• The space within a closed shape

• The length of the longest side

• The number of corners in the shape

How should square tiles be placed to measure area?

• In a circular pattern

• Overlapping each other

• Side by side without gaps or overlaps

• With gaps between them

What is a common mistake when measuring area?

• Counting the tiles twice

• Using different sized tiles

• Confusing area with perimeter

• Confusing area with volume

What do we use when the unit of measurement is unknown?

• Square centimeters

• Square meters

• Square inches

• Square units

How do you find the area of a rectangle on a grid?

• By multiplying the number of corners

• By adding the sides together

• By counting the square tiles covering the shape

• By measuring the length and width
