Maryland Math 6.NOS.A.1
Standard Cluster
Divide fractions by fractions in context. Extend estimation strategies to estimate and assess the reasonableness of quotients. Use and connect concrete and visual fraction models (e.g., linear, regional/area, and set models) and equations to divide. Represent and explain the calculation by connecting fraction models, and/or equations to the meaning of division.

What This Cluster Means
What Students Need to Do
- Students find how many groups of one fraction fit in another, even when the answer includes part of a group. They use fraction strips, drawings, or number lines to show the groups, write a division equation, and check the answer with an estimate.
What Mastery Looks Like
- Given 3/4 cup of flour and 1/2 cup per batch, a student shows one full batch and half a batch. They write 3/4 ÷ 1/2 = 1 1/2 and explain why the answer is between 1 and 2.
Common Misconceptions
- Students may flip the first fraction instead of the divisor, or use the reciprocal rule without knowing what the answer counts. Some count only complete groups or assume division always makes a number smaller.
How to Assess It
- Exit ticket: A recipe needs 1/2 cup of oats per batch, and you have 3/4 cup. Estimate the number of batches, then draw a strip and write a division equation to find the exact amount.

Ways to Teach It
Give pairs strips marked in fourths; have them build 3/4 and show how many 1/2-length groups it contains.
Ask, 'Why is 2/3 ÷ 1/4 greater than 2/3?' Have students sketch a number line and explain their estimate.
Play a card match: pair 3/4 ÷ 1/2 with a shaded area model and 1 1/2, then explain the match.
Post a smoothie recipe using 3/4 cup of yogurt per serving; with 1/2 cup available, students estimate and calculate servings.
