Number Line

Using a number line can provide students with a concrete representation of the value various numbers hold. Sal plots 6 different numbers on a number line. He includes whole, decimal, and negative numbers.

Add depth to your class' understanding of fractions with video seven of this nine-part series. Building on prior experience representing fractions on number lines, young mathematicians learn to identify and extend patterns involving the...

The big question: Is eight eighths equivalent to one? Use a number line to show how to express fractions that are equivalent to one. The concept is introduced first through review and then with visual representations that support lesson...

Number lines are great visual tools that can be used to teach a wide range of math topics. The final video of this series models how to use number lines when solving subtraction problems using the counting up strategy. Pause the video...

Add to the toolbox of young mathematicians by teaching them to compare fractions using number lines. The final video in this series models the process for labeling and comparing fractions on number lines with multiple supporting...

Explicit and direct instruction is great for children who are struggling in math; it is also great for introducing a new topic or idea. Help your learners understand exactly what it means to identify an equivalent fraction on a number...

Step by step, two examples of creating number lines are explained through a series of animations. One is meant to watch at home, the second can be viewed in class, and there is a third tab with two sample problems to try. This skill,...

Can you put a fraction on a number line? You can! As learners will find out, they can break a number line into equal parts just like they can with a block or pie. With an example problem and clear explicit instruction, they'll be guided...

Organization is the best way to make sure that ratios are set up correctly to be proportional. This video reviews how to solve ratio problems with addition and multiplication, shown in more detail in the prior two videos of this series,...

The second of eight videos on rounding whole numbers to the nearest 10 or 100 describes how to use a number line to create benchmark numbers. A review of place value and counting by 10s starts off the lesson, followed by a discussion on...
