This video tutorial introduces fourth-grade students to the concept of decomposing fractions using tape diagrams. It begins with a basic explanation of fractions and their decomposition into unit fractions. The lesson progresses to more complex examples, such as decomposing 7/4, and emphasizes the importance of identifying whole parts in tape diagrams. The tutorial also covers creating number bonds and writing number sentences to represent fractions. The lesson concludes with a preview of future topics in the module.

What is the main focus of the fourth-grade module on fractions?

• Multiplying fractions

What does the denominator in a fraction represent?

• The number of shaded parts

• The number of unshaded parts

• The total number of parts

• The number of equal parts the whole is divided into

How can five-sixths be decomposed using a tape diagram?

• As 5/6 + 1/6

• As 2/6 + 3/6

• As 4/6 + 1/6

What is a possible number bond for seven-fourths?

• 2/4 + 2/4

• 3/4 + 3/4

• 5/4 + 2/4

• Seven parts

What is the fraction represented by one whole plus one-fifth?

• 6/5

• 8/5

• 5/5
