Problem/activity:
Task
 Arrange the fractions in order from least to greatest. Explain your answer with a picture.
 $\frac{1}{5}, \frac{1}{7}, \frac{1}{3} $
 $\frac{2}{5}, \frac{2}{7}, \frac{2}{3} $
 $\frac{5}{6}, \frac{3}{6}, \frac{1}{6} $
 $\frac{5}{12}, \frac{8}{12}, \frac{4}{12} $

Concept/skill: 
Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
 Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.

Answer: 
Yes. By arranging the fractions in this problem, students learn to compare fractions by reasoning about their size.

Now, does the problem or activity shown below enable students to learn the full intent of the following concept or skill?

2 bottles of water cost $5.00.
Fill in the table that shows the costs for 4, 6, and 8 bottles. Find the cost for a single bottle in each case.
{"table": [{"thead": [{"tr": [{"th": [{"_attributes": {"scope": "col"}, "_value": "Number of bottles"}, {"_attributes": {"scope": "col"}, "_value": "Cost (\\$)"}, {"_attributes": {"scope": "col"}, "_value": "Cost per bottle"}]}]}], "tbody": [{"tr": [{"td": [{"_value": "$$2$$"}, {"_value": "$$5$$"}, {}]}, {"td": [{"_value": "$$4$$"}, {}, {}]}, {"td": [{"_value": "$$6$$"}, {}, {}]}, {"td": [{"_value": "$$8$$"}, {}, {}]}]}]}]}
5 granola bars cost $4.00
Fill in the table that shows the costs for 10, 15, and 20 granola bars. Find the cost for a single granola bar in each case.
{"table": [{"thead": [{"tr": [{"th": [{"_attributes": {"scope": "col"}, "_value": "Number of granola bars"}, {"_attributes": {"scope": "col"}, "_value": "Cost (\\$)"}, {"_attributes": {"scope": "col"}, "_value": "Cost per bar"}]}]}], "tbody": [{"tr": [{"td": [{"_value": "$$5$$"}, {"_value": "$$4$$"}, {}]}, {"td": [{"_value": "$$10$$"}, {}, {}]}, {"td": [{"_value": "$$15$$"}, {}, {}]}, {"td": [{"_value": "$$20$$"}, {}, {}]}]}]}]}
Explain why if you can buy $a$ items for $b$ dollars, or buy $2a$ items for $2b$ dollars, the cost per item is the same in either case.
