What is Eureka Math?
Eureka Math is an online textbook-like program that
was developed by Common Core, Inc. a
Washington, DC-based not-for-profit organization
(not affiliated with CCSS) that creates content-rich
curriculum tools. The Eureka website is
www.greatminds.net .
Eureka Math provides an easily navigable online
platform for housing the comprehensive
mathematics curriculum Common Core, Inc.
created for the New York State Education
Department (NYSED), which is housed at
www.engageny.org .
![Page 5: engageNY/Eureka Math Elementary Grades Parent Workshop · 2015-10-06 · Grade 3 Lesson and Coherence •Obj.- Interpret the quotient as the number of groups or the number of objects](https://reader035.fdocuments.in/reader035/viewer/2022081401/5f087f0a7e708231d4224c67/html5/thumbnails/5.jpg)
What is Eureka Math?
• Eureka Math is an enhanced version of EngageNY
Math.
• “Eureka Math is based on research and
development made possible through a partnership
with the New York State Education Department.
• The modules within Eureka Math are available
online at engageny.org and greatminds.net.
Eureka Math added an “array of online resources
for teachers and parents and professional
development” to support the implementation of the
curriculum.

PK-5 A Story of Units
Structured to reflect the instructional shifts:
• Focus – deeply on the concepts prioritized in the
CCSS
• Coherence – learning is connected within and
across grades – each standard is an extension of
previous learning experiences.
• Rigor – pursuits of conceptual understanding,
procedural skills, fluency and application - all with
equal intensity.

Standards for Mathematical Practices
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.

Key Points
• A Story of Units: A Curriculum Overview for Grades P-5
provides a curriculum map and sequence of modules
for the year.
• The focus is on strategies and student reasoning, not on
algorithms.
• Each Module builds on the skills and knowledge of the
previous module. Rigorous problems are embedded
throughout the module

Sprints
• They are designed to develop fluency
• They are fast paced
• Teachers assume role of athletic
coach
• They should be fun, adrenaline rich
activities
• Student recognition of increasing
success is critical
– Every improvement is celebrated

Sprints
• Each sprint has two parts with closely
related problems on each
• Students complete the two parts in
quick succession
• The goal is improving on the second
part.
• Sprints should take about 8 minutes

Application Problems (continued)
• Usually relate to concept
development in lesson
• Suggested use of RDW strategy
• Vignettes are provided and MAY be
used
• Important for students to see
connections between other parts of
the lesson and other concepts.
– Best if students can discover on their own.

Read, Write, Draw Strategy (RDW)
• Assists students to make sense in
problem solving
• Teacher can model for students first,
then guide students together and
have students apply the strategy on
their own

Progression of Learning
• Students need enough concrete
experiences to develop conceptual
understanding
• Students need experience with visual
models to enable the development of
abstract fluency.
• Students learn “why” behind a math
concept not just the “how” so they can
explain their thinking and justify their
solutions.

What are tape diagrams?
• A “thinking tool” that allows students to visually represent a mathematical problem and transform the words into an appropriate numerical operation
• A tool that spans different grade levels
![Page 46: engageNY/Eureka Math Elementary Grades Parent Workshop · 2015-10-06 · Grade 3 Lesson and Coherence •Obj.- Interpret the quotient as the number of groups or the number of objects](https://reader035.fdocuments.in/reader035/viewer/2022081401/5f087f0a7e708231d4224c67/html5/thumbnails/46.jpg)
• A picture (or diagram) is worth a thousand words
• Children find equations and abstract calculations difficult to understand. Tape diagrams help to convert the numbers in a problem into pictorial images
• Allows students to comprehend and convert problem situations into relevant mathematical expressions (number sentences) and solve them
– Bridges the learning from primary to secondary (arithmetic method to algebraic method)
Why use tape diagrams? Modeling vs. Conventional Methods

Progression of Tape Diagrams
• Students begin by drawing pictorial models
• Evolves into using bars to represent quantities– Enables students to become more comfortable
using letter symbols to represent quantities later at the secondary level (Algebra)

Forms of a Tape Diagram
• Part-Whole Model- Also known as the ‘part-part-whole’ model,
shows the various parts which make up a whole
• Comparison Model- Shows the relationship between two quantities
when they are compared

A Story of Units
Key Points – Proficiency with Tape Diagrams
59
• When building proficiency in tape diagraming skills start with simple accessible situations and add complexities one at a time.
• Develop habits of mind in students to reflect on the size of bars relative to one another.
• Part-whole models are more helpful when modeling situations where you are given information relative to a whole.
• Compare to models are best when comparing quantities.

• Promote perseverance in reasoning through problems.
• Develop students’ independence in asking themselves:
–“Can I draw something?”
–“What can I label?”
–“What do I see?”
–“What can I learn from my drawing?”
