Understanding Fractions and Their Operations

Mrs. Lamorn guides students through a lesson on adding and subtracting fractions. The lesson includes activities like identifying which fraction representation doesn't belong, sorting expressions into categories, and using number lines and charts to solve fraction problems. Students learn to find equivalent fractions and use different strategies to add and subtract fractions with different denominators. The lesson concludes with a cool down activity and practice exercises.

Which of the following does not belong in a set of fractions?

• A fraction with only one representation

• A fraction with no sixths

• A fraction that exceeds one

• A fraction with no numbers

What is the relationship between 1/3 and 2/6?

• 1/3 is greater than 2/6

• 1/3 is less than 2/6

• 1/3 and 2/6 are unrelated

• 1/3 is equal to 2/6

How can you categorize expressions with mixed numbers?

• By their numerators

• By their denominators

• By whether they have mixed numbers or not

• By their total value

Why can't you subtract 1/6 from 2/3 directly?

• Because 1/6 is not a proper fraction

• Because 2/3 is not a proper fraction

• Because they have different denominators

• Because 1/6 is larger than 2/3

What is the equivalent of 2/3 in sixths?

• 5/6

• 4/6

• 3/6

• 6/6

How do you add fractions with different denominators?

• Add the numerators directly

• Find a common denominator first

• Multiply the denominators together

• Subtract the smaller denominator from the larger
