standard_description: Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
problem_activity: Narrative
The purpose of this warm-up is to elicit the idea that fingers and 5-frames both show 10 in 2 groups of 5, which will be useful when students use 5-frames to create a 10-frame and represent quantities on 10-frames in later activities.

Activity Synthesis
“How are the fingers and the counters on 5-frames the same?” (Each hand has 5 fingers. Each 5-frame has 5 counters. There are 10 fingers and 10 counters.)
