Representations and Connections
Turn and Talk:• What does it mean for students to represent and
make connections in the mathematics classroom?
Mathematical Representations
Students will represent and describe mathematical ideas, generalizations, and relationships with a variety of methods. Students will understand that representations of mathematical ideas are an essential part of learning, doing, and communicating mathematics. Students should move easily among different representations ⎯ graphical, numerical, algebraic, verbal, and physical and recognize that ⎯representation is both a process and a product.

“Representations are useful in all areas of mathematics because they help us
develop, share, and preserve our mathematical thoughts.
They help to portray, clarify, or extend a mathematical idea
by focusing on its essential features.”
National Council of Teachers of Mathematics. (2000). Principles and Standards for School Mathematics. (p. 206). Reston, VA.
Mathematical Connections
Students will relate concepts and procedures from different topics in mathematics to one another and see mathematics as an integrated field of study. Through the application of content and process skills, students will make connections between different areas of mathematics and between mathematics and other disciplines, especially science. Science and mathematics teachers and curriculum writers are encouraged to develop mathematics and science curricula that reinforce each other.

Brainstorm and Chart
COLOR Partner: • How do you consider representations and
connections when planning for instruction?
• What questions should be considered regarding representations and connections when planning for instruction?
Common Fraction Misconceptions in 3-5
Jot Thoughts: One idea per sticky
What common misconceptions, error patterns, or confusions are evident in grades 3-5 when it comes to fractions?
Rally Share
• Read your sticky note, and place it in the center of the table.
• If someone has the same thing, they can add it to the pile.
• Continue until all ideas have been shared.
• Sort your ideas and label.• Share out whole group.
11
What the Research Says…
Sherman, Richardson, and Yard (2005) suggest several reasons for students’ difficulty in learning about fractional concepts and skills:• They memorize procedures and rules before they have developed a
conceptual understanding of the related concepts.• Children over-generalize what they know about whole-number
computation and apply this knowledge to fractions.• Estimating rational numbers is more difficult than estimating whole
numbers.• Recording fractional notation is confusing if they don’t yet understand
what the top and bottom numbers represent.

RepresentationsDiscuss:• What representations are evident in
the strategies that were used?• What other representations might
support student thinking?• What might be some
representations that could limit student thinking?

Pair Square
Join another pair and discuss:
What connections can be made among strategies?
21
Identify the Mathematical Content
• Examine the fraction learning progression.• Discuss and highlight where the standards are
evident in the mathematics of the task.
Analyze Student Work
• What representations are evident in the student work?
• What does the work tell us about student understanding? Misconceptions?
• How do students communicate understanding?
Clarify Our List
Let’s brainstorm and look back at our list -
Having done the task and looked at student work, what might need to be clarified?

According to Empson and Levi (2011)
• Children come to school with conceptually sound understandings of fractions, even before instruction
• Research shows that the best way to build meaning for fractions is by solving and discussing word problems – starting with equal sharing problems.
32
Empson, S. and Levi, L. (2011). Extending children’s Mathematics – fractions and decimals, Heinemann.
According to Empson and Levi (2011)
• Children should first use pictures and words (e.g., one-half, two-fourths) to describe or represent fractions
• Teachers should gradually incorporate the use of symbols and equations
33
Why Equal Sharing Problems?
• Division into equal groups is a process that young children understand intuitively
• Can be solved by children without direct instruction
• Children do not need to know how to use fraction symbols or terminology to solve these problems
• Can begin as early as kindergarten

What are some ways to represent student thinking in these problems?
Representation should be an important element of lesson planning. Teachers must
ask themselves,
“What models or materials (representations) will help convey the
mathematical focus of today’s lesson?”- Skip Fennell

Role of the Teacher• Create a learning environment that encourages
and supports the use of multiple representations• Model the use of a variety of representations• Orchestrate discussions where students share
their representations and thinking• Support students in making connections among
multiple representations, to other math content and to real world contexts

"Students representational competence can be developed through instruction. Marshall, Superfine, and Canty (2010, p. 40) suggest three specific strategies:
1. Encourage purposeful selection of representations.2. Engage in dialogue about explicit connections among
representations.3. Alternate the direction of the connections made among
representations."
National Council for Teachers of Mathematics. (2014). Principles to Actions. (p. 26). Reston, VA
Role of the Student
• Create and use representations to organize, record, and communicate mathematical ideas
• Select, apply, and translate among mathematical representations to solve problems
• Use representations to model and interpret physical, social, and mathematical phenomena

Students must be actively engaged in developing, interpreting, and critiquing
a variety of representations. This type of work will lead to better
understanding and effective, appropriate use of representation as a mathematical tool.

Ideas for Instruction…
To help students develop a deeper understanding of fractional concepts you can:
• Explore the concept of fair-shares• Provide opportunities for students to share a variety of
objects• Introduce vocabulary without the symbolism• Introduce fractional concepts in the context of things other
than a pizza• Expose students to fractions other than just halves, thirds,
and fourths

45
“Problem difficulty is determined by the relationship between the number of things to be
shared and the numbers of sharers. Because students’ initial strategies for sharing involve
halving, a good place to begin is with two, four, or even eight sharers.”
