Understanding Benchmark Fractions

Miss Robin guides explorers through understanding and comparing fractions using benchmarks. The video covers basic fraction concepts, introduces benchmark fractions, and applies these concepts to solve word problems. Explorers learn to use visual models and number lines to compare fractions with different numerators and denominators, focusing on benchmarks like zero, one-half, and one. The session concludes with a review of key concepts and a summary of the strategies discussed.

What is the main concept discussed when comparing fractions with the same numerators?

• The size of the whole

• The size of the pieces

• The number of pieces

• The color of the pieces

Why can't we use strategies for like numerators or denominators in the new word problems?

• Because the fractions are not real numbers

• Because the fractions are too small

• Because the fractions have unlike numerators and denominators

• Because the fractions are too large

What are benchmark numbers?

• Numbers that are common and easy to visualize

• Numbers that are difficult to visualize

• Numbers that are always even

• Numbers that are always odd

How can benchmark fractions help us?

• By making fractions disappear

• By turning fractions into whole numbers

• By helping us visualize and compare fractions

• By making fractions more complex

What is the benchmark fraction used to compare seven-tenths and five-twelfths?

• Three-fourths

• One-half

• One-fourth

• One whole

Who hiked farther before resting, Colby or Don?

• Colby

• Don

• Both hiked the same distance

• Neither hiked

Which benchmark fraction helps determine who is closer to their reading goal?

• One whole

• Three-fourths

• One-half

• One-fourth

Who is closer to their reading goal, Jocelyn or Jace?

• Both are equally close

• Jace

• Jocelyn

• Neither is close

What benchmark can be used to compare three-fourths and five-sixths?

• One-fourth

• One whole

• One-half

• Three-fourths

Whose car used more gas, Amy's or Tammy's?

• Both used the same amount

• Neither used gas

• Tammy's

• Amy's
