Fraction Comparison and Division Concepts

Mrs. Brewer, a third-grade teacher, uses a Halloween-themed lesson to teach fractions. She uses a cookie to demonstrate how dividing it into parts represents fractions. As more characters like vampires and mummies arrive, the cookie is divided into smaller fractions, illustrating how the size of each piece decreases. The lesson emphasizes comparing fractions with the same numerator and understanding how the denominator affects the size of the fraction. The session concludes with a review of key concepts and a fun game of rock-paper-scissors.

What holiday is approaching that sets the theme for the lesson?

• Halloween

• Thanksgiving

• Christmas

• Easter

What happens to the cookie when the vampire arrives?

• It is thrown away

• It is divided into halves

• It is given to the mummy

• It is eaten whole

How many pieces is the cookie divided into when the mummy arrives?

• Five

• Four

• Three

• Two

What is the fraction of the cookie each person gets when there are four characters?

• One half

• One third

• One sixth

• One fourth

What remains constant in all the fractions discussed by Mrs. Brewer?

• The numerator

• The size of the cookie

• The denominator

• The number of characters

What happens to the size of each piece as more people share the cookie?

• It gets larger

• It disappears

• It stays the same

• It gets smaller

When comparing fractions with the same numerator, what determines the size of the fraction?

• The number of people

• The larger numerator

• The smaller denominator

• The larger denominator

On a number line, which fraction is greater: one half or one fourth?

• Cannot be determined

• One fourth

• One half

• They are equal

What game does Mrs. Brewer play with the students to engage them?

• Simon Says

• Tag

• Hide and Seek

• Rock, Paper, Scissors

What is the key takeaway about comparing fractions with the same numerator?

• The numerator and denominator do not matter

• The larger the denominator, the larger the fraction

• The smaller the denominator, the larger the fraction

• The larger the numerator, the smaller the fraction
