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: Isaiah is thinking of the number 9.52 in his head. Decide whether each of these has the same value as 9.52 and discuss your reasoning. 1. Nine and fift...

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 mini choice board was used as a center in my math class. I used slidesmania to display the options in a fun way. 

Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of various environments and the engineering design process to design and create their own model biodome ecosystems - exploring energy and nutrient flows, basic needs of plants and animals, and decomposers. Students learn about food chains and food webs. They are introduced to the roles of the water, carbon and nitrogen cycles. They test the effects of photosynthesis and transpiration. Students are introduced to animal classifications and interactions, including carnivore, herbivore, omnivore, predator and prey. They learn about biomimicry and how engineers often imitate nature in the design of new products. As everyday applications are interwoven into the lessons, students consider why a solid understanding of one's environment and the interdependence within ecosystems can inform the choices we make and the way we engineer our communities.

This short video and interactive assessment activity is designed to teach fifth graders about comparing decimals and fractions using inequalities.

This short video and interactive assessment activity is designed to give fourth graders an overview of comparing decimals.

This short video and interactive assessment activity is designed to teach fifth graders about comparing the product of decimals without calculation.

This short video and interactive assessment activity is designed to teach fourth graders about comparing decimals with whole numbers using inequalities.

Students will learn how to compare and order decimals.  They will have opportunities to use the <, >, and = symbols to correctly compare decimals, read comparison statements, and then apply that information to ordering decimals from least to greatest and vice versa.

This short video and interactive assessment activity is designed to give fifth graders an overview of comparing decimals.

This is an interactive game in which students practice comparing decimals by choosing the correct symbol to put between the two rain clouds that contain decimals to make the number sentence true.

Students will practice rounding decimals by clicking on the shark containing the correct answer.

In this lesson, the students will use base ten blocks to build and compare decimal numbers.

By the end of this tutorial, you will be able to read and write decimals to the thousandths using base-ten numerals, number names, and expanded form.

This video and support materials focus on using what you know about place value to determine what each digit represents in a number that extends to the hundredths place. Find the value of digits by exploring the number 342.98.

This short video and interactive assessment activity is designed to teach fifth graders about determining less than or greater than values of a decimal.

This short video and interactive assessment activity is designed to teach fourth graders about determining the order of decimals in word problems.

As students delve deeper into their investigations with decimals, this task highlights that the placement of the numbers can be more important than the value of the digits. Just as students use place value drawings in the lower grades to familiarize themselves with ones, tens, and hundreds, fifth graders can gain develop understanding of the decimal places through this task.

CK-12's Grade 5 Elementary Math is a series of videos and interactive videos designed to teach basic math concepts to 5th graders. Concepts covered include Multiplication and Division, Place Value, Multiple Operations and Grouping, Decimals, Time, Fractions, Money, Measurement, and Geometry.
