The object is to model fraction division by asking “How many are in one group?” It is a difficult concept to understand, but developing the model that shows one cup to a certain amount of container or one container to a certain amount of...

Using a number line, pupils are asked to identify which of four fractions is closest to one half. Includes a single problem that can serve as a practice problem or formative assessment for 3rd or 4th graders learning to partition number...

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes a...

Introduce your class to solving one-step equations. In this short video, Sal walks through the process of solving simple equations. He solves the problem and then shows how to check the answer by completing the inverse operation.

Help your students understand how to use their algebraic reasoning to solve a one-step equation, where they must solve for X. Add this video to a lesson or assign it as homework.

Just because it's one step doesn't mean it's simple! A video tutorial describes the process of solving one-step equations. The instructor demonstrates how to solve using addition, subtraction, multiplication, and division inverse...

The method of converting a mixed number to an improper fraction is fully explained in this video. Sal completely details how and why one is able to convert a mixed number. He uses multiple colors and drawings to demonstrate the...

Practice problems are great ways to engage your charges with a new concept. Sal solves for x + 8 less than or equal to 6 and then graphs the solution. First, he subtracts 8 from both sides, and then he subtracts 6. Next, he draws a...

Khan Academy assists your learner in grasping the concept of Place Value. Students will break down the number 4356 as 4 thousands + 3 hundreds + 5 tens + 6 ones, and then labels the number by place value. This video would be most helpful...
