# The coherence map shows the relationships among the standards across multiple topics and grade levels in the common core subjects Math & English (ELA). Coherence map helps teachers/educators diagnose the students mastery in specific topics and it will help students achieve success on that topics/standards.

The Lumos coherence map not only provides graphical representation and convenient navigation within the standards map but also access to thousands of engaging learning resources such as Practice questions, Videos, Books, and Infographics related to every standard. It helps educators and students visually explore the learning standards. It's an useful tool to help students progress through the learning standards.

4.NF.A.1

**Standard Description of 4.NF.A.1:**Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)

### What is the importance of coherence map?

The Coherence map gives educators a visual understanding of Grade Level Standards in both Math and English Language Arts (ELA). Teachers can effortlessly see how each grade level connects to previous and next levels along with the same standard.

### How to use coherence map?

Math and ELA standards for each Grade Level from 3rd grade up through high school are represented on a grid. Teachers simply click on the Grade Level/Content Area that they need to bring up a pop-up list of all the standards connected with it. It’s also possible to navigate to individual Standards by typing them manually into the search bar.
