Eureka Math is a comprehensive mathematics curriculum created by the non-profit organization Great Minds. It is designed to meet the Common Core State Standards for Mathematics and is used in schools across the United States. Eureka Math is known for its unique approach to teaching math that emphasizes problem-solving, critical thinking, and real-world applications of mathematical concepts. Eureka Math is organized by grade level and consists of a set of modules that cover specific mathematical topics. Each module includes a series of lessons, assessments, and homework assignments. The curriculum is designed to be taught in a coherent and sequential manner, with concepts building on each other throughout the year. One of the key features of Eureka Math is the use of a problem-based approach to learning. Lessons often begin with a real-world problem or scenario that students must solve using mathematical concepts. This approach encourages students to think deeply about math and how it applies to their lives. Overall, Eureka Math is a comprehensive and engaging curriculum that has been praised for its effectiveness in helping students learn and understand mathematical concepts.

Lesson 13 of Eureka Math focuses on multiplication and division. Students learn how to use multiplication and division to solve problems involving equal groups, arrays, and measurement quantities. The lesson also introduces students to the concept of division as a missing factor problem.

• Read and understand the lesson: Before attempting the homework, make sure you have a good understanding of the concepts covered in the lesson. Read through the lesson carefully and take notes if necessary.
• Do the practice problems: The lesson usually includes practice problems that are similar to the homework. Take the time to work through them to reinforce your understanding of the concepts.
• Manage your time: Set aside a specific amount of time to complete the homework. This will help you avoid procrastination and ensure that you have enough time to complete the assignment.
• Break the problems down: If a problem seems overwhelming, break it down into smaller, more manageable parts. This can make the problem less intimidating and easier to solve.
• Use resources: Don't be afraid to use resources such as the textbook, notes, or online resources if you're stuck on a problem. These can provide valuable guidance and help you better understand the material.
• Check your work: Once you've completed the homework, double-check your work to ensure that you've answered all the questions correctly. This will help you identify any mistakes you may have made and give you the opportunity to correct them before turning in the assignment.

Here are some sample questions and answers from Eureka Math Lesson 13 homework: Question 1: Use repeated addition to find the total number of marbles in 5 bags, where each bag contains 4 marbles. Answer: To find the total number of marbles, we can use repeated addition: 4 + 4 + 4 + 4 + 4 = 20. So there are 20 marbles in 5 bags. Question 2: Divide 18 by 3 using repeated subtraction. Answer: We can use repeated subtraction to find the answer: 18 - 3 = 15, 15 - 3 = 12, 12 - 3 = 9, 9 - 3 = 6, 6 - 3 = 3. So 18 ÷ 3 = 6.

Eureka Math Student Materials: Grades K–5

Learn, Practice, Succeed

Learn, Practice, and Succeed from   Eureka Math™   offer teachers multiple ways to differentiate instruction, provide extra practice, and assess student learning. These versatile companions to   A Story of Units®   (Grades K–5) guide teachers in response to intervention (RTI), provide extra practice, and inform instruction.

Also available for Grades 6–8 . 

Learn, Practice, Succeed can be purchased all together or bundled in any configuration. Contact your account solutions manager for more information and pricing.  

The Learn book serves as a student’s in-class companion where they show their thinking, share what they know, and watch their knowledge build every day!

Application Problems:  Problem solving in a real-world context is a daily part of   Eureka Math , building student confidence and perseverance as students apply their knowledge in new and varied ways.

Problem Sets :  A carefully sequenced Problem Set provides an in-class opportunity for independent work, with multiple entry points for differentiation.

Exit Tickets:   These exercises check student understanding, providing the teacher with immediate, valuable evidence of the efficacy of that day’s instruction and informing next steps.

Templates:   Learn   includes templates for the pictures, reusable models, and data sets that students need for   Eureka Math   activities.

With   Practice , students build competence in newly acquired skills and reinforce previously learned skills in preparation for tomorrow’s lesson.   Together,   Learn   and   Practice   provide all the print materials a student uses for their core instruction.

Eureka Math  contains multiple daily opportunities to build fluency in   mathematics . Each is designed with the same notion—growing every student’s ability to use mathematics   with ease . Fluency experiences are generally fast-paced and energetic, celebrating improvement and focusing on recognizing patterns and connections within the material.

Eureka Math   fluency activities provide differentiated practice through a variety of formats—some are conducted orally, some use manipulatives, others use a personal whiteboard, or a handout and paper-and-pencil format.

Sprints:  Sprint fluency activities in  Eureka Math Practice  build speed and accuracy with already acquired skills. Used when students are nearing optimum proficiency, Sprints leverage tempo to build a low-stakes adrenaline boost that increases memory and recall. Their intentional design makes Sprints inherently differentiated – the problems build from simple to complex, with the first quadrant of problems being the simplest, and each subsequent quadrant adding complexity.

Eureka Math Succeed   enables students to work individually toward mastery.  Teachers and tutors can use  Succeed   books from prior grade levels as curriculum-consistent tools for filling gaps in foundational knowledge. Students will thrive and progress more quickly, as familiar models facilitate connections to their current, grade-level content.

Additional Problem Sets:  Ideal for Homework or extra practice, these additional problem sets align lesson-by-lesson with what is happening in the classroom. These problems are sequenced from simple-to-complex to naturally scaffold student practice. They align with   Eureka Math   and use the curriculum’s mathematical models and language, ensuring that students feel the connections and relevance to their daily instruction, whether they are working on foundational skills or getting extra practice on the current topic.

Homework Helpers:   Each problem set is accompanied by a Homework Helper, a set of worked examples that illustrate how similar problems are solved. The examples, viewed side by side with the homework, support students as they reinforce the day’s learning. Homework Helpers are also a great way to keep parents informed about math class.

Bundles and Class Sets Available

Bundle options are available for all of our materials (print, digital, PD, etc.). Prices vary by grade and size of class set. Certain grade-levels do not include all packets due to the nature of the grade-level content. Student workbooks are available in class sets of 20, 25, and 30. Prices vary by size of class set .
