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: Explain why $0.4\times10=4$. Explain why $3.4\times10=34$. Draw pictures to illustrate your explanations....

This unit focuses on three fifth grade standards. These standards include understanding the place value system from one million to the thousandths place.

This parent guide supports parents in helping their child at home with the 5th grade Math content.

This resource accompanies our Rethink 5th 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. 

This choice board will work best after teaching all of the NBT standards as it includes choices for multiplying whole numbers, dividing whole numbers, adding and subtracting decimals, and dividing decimals. 

This lesson is for Grades 4-5 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 define a molecule and list the basic components and structure of the atom. They will also understand how engineers use their knowledge of atomic structure to design new technologies.

Working in teams of three, students perform quantitative observational experiments on the motion of LEGO MINDSTORMS(TM) NXT robotic vehicles powered by the stored potential energy of rubber bands. They experiment with different vehicle modifications (such as wheel type, payload, rubber band type and lubrication) and monitor the effects on vehicle performance. The main point of the activity, however, is for students to understand that through the manipulation of mechanics, a rubber band can be used in a rather non-traditional configuration to power a vehicle. In addition, this activity reinforces the idea that elastic energy can be stored as potential energy.

This short video and interactive assessment activity is designed to teach fifth graders about the conversion of decimals to fractions.

This short video and interactive assessment activity is designed to teach fifth graders about dividing decimals by multiples of 10.

This short video and interactive assessment activity is designed to teach third graders an overview - thousandths.

This short video and interactive assessment activity is designed to teach second graders an overview - tenths.

Students solve decimal place value problems. For each correct answer, students earn seven points, but they lose three points for each incorrect answer.
