SVMI FAL: Interpreting Fractions
Read through the task and answer the questions the way you think a“typical” student would.
On the back, jot down what you think the students in your classes (or district[s] you work with) might struggle with and why.
Also jot down the big mathematical ideas in this task.
SVMI FAL: Interpreting Fractions
Directions to students:
•Attempt this task on your own.
•Answer as much as you can. Show your work so I (the teacher) can understand your reasoning. Don’t worry if you can’t do everything. There will be a lesson on this material that will help you improve your work.
SVMI FAL: Interpreting Fractions
• Collect students’ responses to the task. Make some notes on what their work reveals about their current levels of understanding and their problem solving strategies.
• We suggest that teachers do not score students’ work. The research shows that this will be counterproductive.
Introduction to Interpreting Fractions
• On your mini-whiteboard show me a rectangle.
• Show me a rectangle divided into two halves.
• Show me a circle divided into four fourths.
• Show me three fourths of this circle. Write three fourths as a fraction representing this quantity.
Introduction to Interpreting Fractions
• On your mini-whiteboard show me a line having a dot at its beginning and a dot at its end.
• Show me this line segment divided into four fourths.
• Show me this same line segment divided into eight eighths.
• Show me on this same line segment where to find seven eighths. Write the fraction representation for this quantity.
Introduction to Interpreting Fractions
• On your mini-whiteboard show me a set of six buttons using circles for the buttons.
• Show me a one half of this set of buttons. Write the fractional representation for this quantity.
• What does this fraction represent?
• Who would be willing to justify their numerical representation?
Introduction to Interpreting Fractions
• On your mini-whiteboard show me a set of five tiles using a square to represent each tile.
• Show me a three fifths of this set of buttons. Write the fractional representation for this quantity.
• What does this fraction represent?
• Who would be willing to justify their numerical representation?

Collaborative Task(Continues with the same mathematical ideas)
• Please move into groups of 2 or 3 (self selected).
• Each group will be given five sets of cards: • Set A: Symbolic
Notation • Set B: Area Models• Set C: Measurement
Models• Set D: Set Models• Set E: Fractional
Situations
Collaborative Activity
• Take turns matching a fraction represented by a number with an area model.
• Each time you find a match, explain your thinking clearly and carefully to your partners.
• If you think there is no suitable card that matches, create one of your own. There are some blank cards for doing this.
• When you have agreed all the cards, place them side-by-side on your large sheet of paper.
• Find another group across the room to share your thinking with; have a discussion.
Collaborative Activity
• Take turns matching a measurement model to your selected pairings from the first match of a fraction represented by a number with an area model.
• Each time you find a match, explain your thinking clearly and carefully to your partners.
• If you think there is no suitable card that matches, create one of your own. There are some blank cards for doing this.
• When you have agreed on all the cards, place them side-by-side on your large sheet of paper.
• Find another group across the room to share your thinking with; have a discussion.

Collaborative Activity: Teacher’s Role
Teachers are to:
•Listen and watch students carefully.
•Note different student approaches to the task.
•Notice any difficulties that students encounter, and the ways they justify and explain to each other.
•Try not to make suggestions that move students towards a particular approach to the task. Instead, ask questions that help students to clarify and promote thinking.
WHOLE CLASS DISCUSSION
Please post completed posters.
Which cards were easiest? Why?
How did you decide which cards to match?
How can you justify why the different types of models convey the same fractional part?
Plenary Discussion
Write the fractions represented by a number with each representation.
On your mini-whiteboard: •Show me three fourths of a whole rectangle.
•Now, show me three fourths of a set of sticks.
•Show me two thirds of a folded paper stip.
•Now, show me two thirds of a set of hearts.
•Show me one and one quarter pizzas.
•Now, show me one and one quarter on a number line.
SVMI FAL: Interpreting Fractions
Directions to students: •“Please do this task on your own.”
•Teacher collects tasks to take notes on students’ thinking.
•“Look at your original work with the feedback questions.”
•“What have you learned from doing this lesson?”
•“What are you still struggling with?”

LESSON ANALYSIS/REFLECTION
What mathematics can students learn, or deepen their understanding of, with this lesson?
What may they struggle with in this lesson? How is the lesson designed to support struggling students?
How is this lesson like and different from what goes on in your district’s mathematics classrooms?
What do you think are the benefits of using a lesson like this?
What can teachers learn about their students from using lessons like this? What can students learn about themselves from lessons like this?
LINKS TO COMMON CORE STANDARDS
Mathematical ContentNumber and Operations with Fractions3.G.A. 2: Partition shapes into parts with equal
areas3.NF.A.1, 2, 3: Develop understanding of
fractions as numbers4.NF.A.1 & 2: Extend understanding of fraction
equivalence and ordering
Mathematical Practice1.Can explain correspondences and relationships
and draw diagrams to help conceptualize and solve a problem.
THE STRUCTURE OF FORMATIVE ASSESSMENT CONCEPT
LESSONS• Lesson: The pre-assessment task and the
lesson activities are exemplars of the CCSS (content and Practice Standards which have high DOK levels).
• Feedback: The lesson provides opportunities for both teachers and students to gather information about their mathematical understanding/skills. Feedback is given to push thinking and learning forward. Thus, there are no value judgments made or grades given.
• Revisions: There are opportunities for students to revise/advance their thinking and their work.
• Timing: Formative assessment is happening during instruction where there is still time to adapt the lesson to meet the needs of the students.
