Numerator and Denominator

Young mathematicians utilize video, the internet, and hands-on learning experiences in order to recognize that fractions aren't as "scary" as they first appear, and that we use them every day in our lives. The hands-on activities in this...

Mix things things up in your elementary math class with a series of problem-solving exercises. Presented with a series of mixed number word problems, young mathematicians are asked to solve them by using either visual fraction...

Do not use the easiest but the first. The video shows a method to find a common denominator by finding the least common denominator to add fractions. By listing the multiples of the denominators, learners easily identify the least common...

Here's an interactive that will be a great match for math lesson plans. Young mathematicians use an interactive game to match fractions represented numerically and as fraction models. One game assesses fractions only, while the other...

The first step in adding mixed numbers is to change them into improper fractions. Secondly, make sure the denominators are the same. If they are not the same, then find a common denominator. Make the proper conversions to the numerator...

The instructor explains that an improper fraction is a fraction in which the numerator is greater than the denominator. Use this as an at-home review for learners who are struggling to grasp this concept. 

Combining fractions with unlike denominators. Wait! You can't do that! You have to have common denominators to combine the numerator of fractions. Here's a quick review of changing the denominator by multiplying each fraction by that...

Put fractions with different original denominators in order using the least common denominator. Once she has shown how to find the least common denominator, an instructor constructs equivalent fractions that are more easily compared to...

You've got three fractions to add together. Wait! They have unlike denominators. So the first thing you have to do is find the least common denominator. Now multiply the terms so they all have the same denominator. Don't forget to...

Want to add fractions? Well, if they have the same denominator it's going to be so easy. Just add the numerator values together and keep the denominator the same. Easy as that.
