Comparing Fractions with Different Denominators Using Area Models

This video tutorial teaches how to compare fractions with different denominators using area models. It begins by explaining the basics of fractions, including numerators and denominators, and highlights common mistakes in fraction comparison. The tutorial then uses visual models to compare fractions like 2/3 and 3/8, and 4/5 and 4/10, demonstrating that larger denominators result in smaller parts. The lesson emphasizes the importance of considering both numerators and denominators when comparing fractions.

What does the numerator in a fraction represent?

• The number of equal parts a whole is divided into

• The number of shaded parts in a model

• The size of each part in a fraction

• The total number of parts in a whole

When comparing 2/3 and 3/8 using area models, which fraction is larger?

• It cannot be determined

• They are equal

• 3/8

• 2/3

Why might someone incorrectly think 3/8 is larger than 2/3?

• Because the denominators are the same

• Because the numerators are the same

• Because 8 is greater than 3

• Because 3 is greater than 2

Why is 4/5 greater than 4/10?

• Because 5 is greater than 10

• Because the parts in 4/5 are larger

• Because the numerators are different

• Because 4/10 has more parts

What happens to the size of each part when a whole is divided into more equal parts?

• The parts remain the same size

• The parts disappear

• The parts become smaller

• The parts become larger
