Trang 1Introduction to Using
Visual Representations in
Math
Trang 2What is Using Visual Representations?
• Using visual representations is a strategy to display and think
through mathematical information
• Students draw upon visual representations when they are working
to understand a concept or problem
Trang 3Key Elements of Using Visual
Representations
• Students choose and use visual representations to help them solve problems
• Possible displays of information include:
• Number lines
• Arrays
• Pictures of geometric
• Graphs
• features
Trang 4How Does Using Visual Representations Help
Students?
• Provides a concrete way to work with abstract mathematics without
a physical model
• Supports students in moving from informal to formal representations
of mathematical ideas
• Helps students remember and relate to the abstract symbols most often used in mathematics
Trang 5Discussion Questions 1
1 When you introduce your students to visual
representations, what are the key elements that are important to highlight?
2 How can you use visual representations to
support your students as they solve
problems?
3 How can you use visual representations to
support your students’ learning and
understanding of mathematical concepts?
Trang 6How Can I Support Students' Use of Visual Representations?
Trang 7Use Evidence-Based Instructional Practices
• Provide clear explanations
• Use varied examples, materials, and models
• Provide ongoing formative assessment
Trang 8Differentiated Instruction
• Plan instruction that considers students' readiness, learning needs, and interests
• Use a range of technology tools to:
– engage learners at varying levels
– engage learners in multiple ways
– offer students options for demonstrating
understanding and mastery
Trang 9Teacher-Dependent Ways to Differentiate
• By Content
– Different levels of reading or resource materials, reading
buddies, small group instruction, curriculum compacting, multi-level computer programs and Web Quests, audio materials, etc.
• By Product
– Activity choice boards, tiered activities, multi-level learning
center tasks, similar readiness groups, choice in group work, varied journal prompts, mixed readiness groups with targeted roles for students, etc.
• By Process
– Tiered products, students choose mode of presentation to
demonstrate learning, independent study, varied rubrics,
mentorships, interest-based investigations
Trang 10Student-Dependent Ways to Differentiate
• By Readiness
– Options in content, topic, or theme, options in the tools needed for production, options in methods for engagement
• By Profile
– Consideration of gender, culture, learning styles,
strengths, and weaknesses
• By Process
– Identification of background knowledge/gaps in
learning, vary amount of direct instruction, and
practice, pace of instruction, complexity of activities, and exploration of a topic
Trang 11Discussion Questions 2
1 How does the use of visual representations support the CCSS
Mathematical Practices and the UDL principles?
2 How have you used technology to differentiate instruction to
construct and use visual representations?
Trang 12Provide Clear Explanations
• Explain the connection between the problem and the
representation
• When students find a solution, be sure they connect the
representation to the solution in terms of the original problem
• Highlight for students, or have students tell you, what each
dimension represents when more than one dimension is used
Trang 13Use Varied Examples, Materials, and Models
• Share alternative visual representations and discuss their
similarities and differences
• Offer students a variety of tools to create visual representations
• Vary representations’ shapes/orientations so students only focus on the important features
Trang 14Provide Ongoing Formative
Assessment
• Have students identify a missing feature from a representation, such
as a graph or a table
• Ask questions that guide students’ thinking about the information they can get from a visual representation
• Observe students to assess their ability to choose appropriate
representations and their understanding of representations
Trang 15Use Online and Offline Tools
• Manipulatives
• Interactive whiteboard
• Web-based applets
• Math drawing tools
• Calculators
• 3D design software
• Graphing and charting software
Trang 16Use Research-Based Strategies
and Tools
• To launch the lesson
• During the learning task
• As you bring closure to the lesson
Trang 17Discussion Questions 3
1 What challenges have your students had
when using visual representations?
2 How do you help your students to determine
an appropriate visual representation for a
particular problem or situation?
3 How can you use visual representations as a
response to student difficulties or
misconceptions?
