Measuring Area with Different Units of Measure

The video tutorial teaches how to find the area of a shape using a key to determine the unit of measure. It explains the use of keys in picture graphs to count items like votes and demonstrates how different grid paper sizes affect area measurement. The tutorial provides examples of calculating area using square centimeters and square inches, emphasizing the importance of checking the key for accurate measurement. The lesson concludes with a review of the key concepts covered.

What does a key on a picture graph help you determine?

• The color of the pictures

• The number of pictures

• The unit each picture represents

• The size of the pictures

If one picture represents 10 votes, how many votes do three pictures represent?

• 10 votes

• 20 votes

• 30 votes

• 40 votes

Why is it important to check the key when using grid paper to measure area?

• To understand the unit of measurement

• To find the perimeter of the shape

• To know the color of the grid

• To count the number of shapes

What is the area of a shape if it covers 12 square centimeters on grid paper?

• 12 square centimeters

• 12 square meters

• 12 square feet

• 12 square inches

How does the size of grid squares affect the measurement of area?

• It changes the color of the shape

• It alters the perimeter of the shape

• It affects the calculated area

• It modifies the shape's volume
