Unit 7: Lesson 1-3 Review Target/Objective: I can identify fractional parts of collections and on a number line. I can describe and compare the likelihood of an event by using probability.

Fraction Review A fraction is always a fraction of something – for example, ½ of an orange or ⅗ of a mile. This “something” is called a whole. The parts into which the whole is divided must be the same size – they must be “fair shares.”

Fraction Review The number below the fraction bar is called the denominator. It names the number of equal parts into which the whole is divided. The number above the fraction bar is called the numerator. It names the number of parts under consideration. – For example, if Sue ate ⅔ of a pizza, the pizza is the “whole.” The fraction ⅔ tells us that the pizza was divided into 3 equal parts, and Sue ate two of them. Numbers such as 2 ½ and 1 ⅗ are called mixed numbers.

Fraction Review Decomposing fractions – writing fractions and mixed numbers as sums. Example: ⅘ can be decomposed into the sum of ⅕ + ⅗ or the sum of ⅖ + ⅖.

Fractional Parts of a Whole There are 36 sailboats that make a “whole.” Draw a picture and figure out a way to divide the sailboats into fourths. How many sailboats make up ¼? Circle ¾ of the boats.

1 whole = 36 sailboats ¼ = 9 sailboats ¾ = 27 sailboats

Fractional Parts on a Number Line 01 2 Draw the number line below and fill in the fractional parts… ⅗ 1 ⅖

Probability (Think about EVEN parts of a whole) 1 out of 8 2 out of 8 or 1 out of 4 3 out of 8

Practice Work You will be given three practice worksheets. – Take you time and do your best work. – Work each problem by yourself; then check your work with your shoulder partner. – If you need help, PLEASE let me know and I will come help you. Time: End of Class Level: 0-1

Wrap Up! Did we achieve our target/objective? – I can identify fractional parts of collections and on a number line. I can describe and compare the likelihood of an event by using probability. Individuals: Get ready to move classes!
