The document introduces fractions and their key components. It explains that a fraction represents a part of a whole and is written with a numerator over a denominator. The numerator indicates the part being used, and the denominator indicates how many equal parts make up the whole. Examples of fractions represented on number lines and circles are provided, including 1/4, 1/2, 3/4, 6/7, and 5/9. Mixed numbers containing both a whole number and fractional part are also introduced, with the example given of 1 1/5.

5. Okay, so how do I show fractions?

7. Let’s look at the parts of a fraction. 1 2 NUMERATOR DENOMINATOR The Numerator shows what part of the whole is being used The Denominator shows how many pieces make up the whole!

10. The Numerator and Denominator The denominator has been increased to 5. As the denominator increases, the fraction decreases in size.

12. The Mixed Number The mixed number 1 1/5 has a whole number part 1 and a fraction part 1/5.

13. Now you know the basics! Time to get started on converting between mixed numbers and improper fractions!
