Adding Fractions with Equal Denominators

Sam and Adam are building a pet house and placing tiles on the floor. The video explains how to represent the placement of tiles as fractions, starting with 1/16 for one tile. It then demonstrates how to add fractions with the same denominator by adding the numerators, using the example of adding tiles placed by Sam and Adam. The lesson concludes with a summary of how to add fractions with equal denominators using area models.

What fraction of the floor does the first tile placed by Sam represent?

• 1/4

• 1/8

• 1/16

• 1/2

After Adam places two tiles, what fraction of the floor is covered?

• 3/16

• 5/16

• 4/16

• 2/16

What is the result of adding the fractions 1/16 and 2/16?

• 4/16

• 3/16

• 2/16

• 1/16

Why does the denominator remain unchanged when adding fractions with the same denominator?

• Because the total number of tiles changes

• Because the total number of spaces remains the same

• Because the numerator changes

• Because the tiles are different colors

If Sam adds two more tiles, what is the new fraction representing the tiles on the floor?

• 4/16

• 5/16

• 6/16

• 7/16

What is the key takeaway from the lesson on adding fractions?

• Subtract numerators and change the denominator

• Multiply numerators and denominators

• Always change the denominator

• Add numerators and keep the denominator the same

How many tiles in total are placed by Sam and Adam at the end of the lesson?

• 3

• 4

• 6

• 5
