In Grade 2, students were introduced to the fractions halves, thirds, and fourths for the first time. They learned how to relate equal parts to a whole using fractional notation.

In grade 3, students will work with fractions of wholes that are divided into more than 4 equal parts. Students will learn new concepts such as equivalent fractions and identifying a fraction of a set. It is at this grade that students develop an understanding of the meanings and uses of fractions, such as representing parts of a whole, parts of a set, and points or distances on a number line.

At then end of the chapter, students learn to read, write, and identify fractions of a set and then find the relating number of items. As much as possible, pictorial representation has been used to illustrate each real-world problem. The exposure to real-world problems helps students to make sense of what they have learned in parallel context situations encountered in everyday life.

Remember, a fraction describes <b>equal</b> parts of a whole. The quilt is the whole, and the squares which are of equal sizes are the equal parts. Each equal part is a fraction of the whole.

Each fraction model shows equal parts that form a whole. A whole can be different shapes and sizes, and made up of many different parts!

To describe a fraction, we use different vocabulary. 1/5 = one-fifth, 1/9= one-ninth. Don't forget that "th" at the end! Remember that "five" turns into "fifth", and twelve is written "twelfth".

How do we label different parts of a fraction?

If fractions are difficult for you to understand, it sometimes helps to use unifix cubes or blocks to figure out parts of a whole. We'll do some examples in small groups!
