This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: How does the value of a fraction change if you double its numerator? Explain your answer. How does the value of a fraction change if you double its den...

This parent guide supports parents in helping their child at home with the 4th grade Math content.

This resource accompanies our Rethink 4th Grade Math course. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning. 

The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of selected math standards. Each video is an audiovisual resource that focuses on one or more specific standards through examples and illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard, although the examples can be adapted for instructional use.

Students will apply fourth grade concepts of equivalent fractions, decimals, and symmetry to create artwork. Once all students have created their masterpieces, they will have a conversation to compare and contrast the various pieces.  Through teacher questioning, this conversation will lead to a deeper understanding of equivalent fractions and decimal fractions.  This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

This lesson is for grades 4-5 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation. Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.

Students will apply fourth grade concepts of fractions to develop a planned community that meets specific requirements.  Throughout this task, students will need to think about fractions as part of a set and part of a whole area.  The will compare fractions, find fraction equivalences, and add fractions with unlike denominators to ensure that the sum is one whole.  Once all students have created the maps of their communities, they will have discussion to compare and contrast the fractional parts of each person’s community.  This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

This short video and interactive assessment activity is designed to teach fifth graders about ordering fractions with different denominators.

In this lesson, students learn how to compare fractions. Students begin by drawing a picture to compare fractions then interact with a computer program.

In this activity students play a game to compare fractions with a focus on providing explanations for deeper conceptual understanding. There are several versions of the game to meet learners needs and expand opportunities to other math standards.

This activity is designed for pairs of students. Students use a set of cards and a fraction mat to compare fractions using the benchmarks ½ and 1. Several sets of cards and mats are included to differentiate and extend the activity.

This short video and interactive assessment activity is designed to teach fifth graders about comparing fractions using lcm - word problems.

This short video and interactive assessment activity is designed to teach fifth graders about comparing fractions using a fraction bar illustration.

In this online interactive, students identify fraction size with addition and subtraction by using comparison symbols.

This task requires students to provide reasoning as to why fractions are fractions of a specific whole. Students will employ many of the mathematical practices of the Common Core State Standards while crafting their reasoning and presenting their thinking.

In this lesson plan, students are given various activities that will require them to compare and order fractions.

This lesson is for grades 4-5 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation. Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.

For this interactive, students compare two fractions with different numerators and different denominators by playing against students around the world in a game of tug of war to compare fractions.

In this lesson students learn to create equivalent fractions between fifths and tenths (and then some other denominators) as a means to compare fractions of like denominators.

Students explore reference points or benchmarks for zero, one half and one. These benchmarks are used to help compare the relative sizes of fractions, through estimating, ordering and placing them on a number line.
