Example:
Concept/skill: 
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
 Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.

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} $

Answer: 
No. Completing this task does not involve representing fractions on a number line diagram.

Now, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

standard_description: Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
problem_activity: Narrative
The purpose of this activity is for students to compare shapes by covering them with pattern blocks. Students experience tiling as a way to see which shape covers the most space. There are several ways to tile the shapes, but it may prove most useful to use the same units, such as triangles. The rectangle can only be fully tiled with square pattern blocks. To compare shapes B and C, students will need to notice that the rectangle and parallelogram can be made the same length, but the square pattern blocks used to tile the rectangle are taller than the blocks used to tile the parallelogram.

The work here prepares students to tile figures with square tiles in the next lesson and to think of area in terms of square units.
MLR8 Discussion Supports.
Synthesis: Create a visual display of shapes A, B, and C. As students discuss their comparisons, annotate the display with their observations. For example, when comparing shape B to C, write “same length, but taller.”
Advances: Speaking, Listening
Action and Expression: Develop Expression and Communication.
Synthesis: Identify connections between strategies that result in the same outcomes but use differing approaches.

Pattern Blocks to Compare Shapes
Required Preparation
Each group of 2 needs at least 2 hexagons and trapezoids,  4 squares and rhombuses, and 8 triangles.
Launch
Groups of 2
Give each student a copy of the blackline master.
Give each group pattern blocks.
Display the first two shapes (the hexagon and the heart-shaped octagon).
“What do you notice? What do you wonder?” (Students may notice: Both shapes could be made with pattern blocks. The second shape looks like the first shape, but it’s been bent. Students may wonder: Which shape covers more space? Which shape is larger?)
1 minute: quiet think time
Share and record responses.
“Which shape covers more space? How do you know?” (We can cover them with the same blocks, so they cover the same amount of space.)
2 minutes: partner discussion
Share and record responses.
Activity
“Let's continue comparing shapes. Work with your partner to decide which of these shapes covers the most space. Use pattern blocks if they are helpful.”
5 minutes: partner work time
Monitor for students who:
use pattern blocks to determine which shape covers the most space
notice that shape B and C would be the same length if one of the ends of B was moved over, but C covers more space because it is taller
Student Facing
Your teacher will give you handouts with some shapes on them.
Use pattern blocks to decide which shape covers the most space. Be ready to explain your reasoning.

Activity Synthesis
Ask selected students to share strategies for tiling each shape with pattern blocks and how the tiling helped them decide which shape covers the most space.
“When we decide which shape covers the most space, we are talking about the area of a shape. We can think about the
area as the amount of space covered by a shape.”
“Which of these shapes has the greatest area?” (C takes up the most space, so it has the greatest area.)
