Here we learn about how to name fractions, and how to write them. The top number tells us the number of parts we have, and the bottom number tells how many equal parts the whole is divided into. Mathy and I also show you how to draw "pie pictures" - how to divide a circle into two, three, four, five, six, or eight equal parts.

When the two fractions have the same kind of parts (same denominator) or the same amount of parts (same numerator), comparisons are easy. Find math videos for 3rd grade: Math Mammoth Grade 3 Curriculum: Online practice for ordering fractions on a number line:

Sometimes we cannot compare two fractions, or if we do, we end up with strange situations. When is a comparison valid? It turns out, the wholes that the fractions refer to have to be the same size.

In this video, we look at how to compare fractions by drawing number lines. This is the 2nd part of this lesson for 3rd grade math. The first part deals with comparing fractions with the same number of parts or the same amount of parts, and is found here:

We look at a bunch of visual models (pie models, squares, number lines) in this video, learning about equivalent fractions. I also make chains of equivalent fractions - we can see a pattern! Math Mammoth Grade 3 curriculum Online practice for equivalent fractions with visual models
