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: Maned wolves are a threatened species that live in South America. People estimate that there are about 24,000 of them living in the wild.

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. 

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.

This interactive/virtual manipulative provides base ten blocks that consist of individual "cubes," "rods," "flats," and "thousands-cube" (ten of each set for base 10). The activity reinforces students' knowledge of thousands, hundreds, tens, and ones. Students can either enter a number and see the visual representation, or they can create a number by selecting the appropriate base ten blocks. As students add or remove base 10 blocks, they can see the numbers increase or decrease to determine if they are on the right track.

This short video and interactive assessment activity is designed to teach third graders about place value problems involving grouping of items.

In this activity, students will work in small groups to change a chocolate chip cookie recipe that feeds 10 to one that feeds 100. Then students will change it again to feed 2000.

This lesson requires the students to generalize concepts of place value, multiplication, and division in order to compute the number closest to 1,000 using a calculator. Students will engage in mathematical discourse on the topics of comparing numbers and how multiplication changes the value of a number.

In this lesson students are introduced to place value into the 10,000s through the use of an abacus. They practice writing and recognizing large numbers.

This project creates a classroom tool that can be used throughout the year. Color-coded strips of paper represent ones, tens, hundreds, and all the way up to millions.

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

This short video and interactive assessment activity is designed to teach fourth graders about forming largest and smallest numbers (includes even and odd).

G4M1: Place Value, Rounding, and Algorithms for Addition and Subtraction. Contains 19 Lessons.

In this lesson, students represent numerically four-digit dividend division with divisors of 2, 3, 4, and 5, decomposing a remainder up to three times.

In this lesson, students solve division problems with a zero in the dividend or with a zero in the quotient.

This is from Tools for NC Teachers. Students explore the value of a group of one type of coin and consider how changing the value of the coins changes the value of the group. This is remixable.

This resource allows you to assess student understanding of various math concepts, through writing
