This short video and interactive assessment activity is designed to teach second graders an overview of mixed operations (numbers to 1,000).
This short video and interactive assessment activity is designed to teach third graders about number riddles (numbers up to 100,000).
This activity will help students to connect the numeral (symbol) to the number (quantity in a set).
Anything you can do with whole numbers, you can do with decimals. Subtraction is no exception. In this tutorial, you'll get some good practice subtracting decimals! Common Core Standard: 5.NBT.B.7
The real world is seldom about whole numbers. If you precisely measure anything, you're likely to get a decimal. If you don't know how to multiply these decimals, then you won't be able to do all the powerful things that multiplication can do in the real world (figure out your commission as a robot possum salesperson, determining how much shag carpet you need for your secret lair, etc.). Common Core Standards: 5.NBT.B.5, 5.NBT.B.7

When students plot irrational numbers on the number line, it helps reinforce the idea that they fit into a number system that includes the more familiar integer and rational numbers.
This short video and interactive assessment activity is designed to teach fifth graders about multiplying and dividing - missing operation.
This 4-minute video lesson introduces Khan's series on complex numbers.
The purpose of this task is to help students understand and articulate the reasons for the steps in the usual algorithm for converting a mixed number into an equivalent fraction.
This is a fun way for students to create complex math problems thinking about Order of Operations.
This lesson unit is intended to help teachers assess how well students are able to understand and use directed numbers in context. It is intended to help identify and aid students who have difficulties in ordering, comparing, adding, and subtracting positive and negative integers. Particular attention is paid to the use of negative numbers on number lines to explore the structures: starting temperature + change in temperature = final temperature final temperature Đ change in temperature = starting temperature final temperature Đ starting temperature = change in temperature.
Students can practice plotting rational numbers on a number line. Using Geogebra students can click and drag the points onto the number line. cc by 4.0 University of Utah
