Fractions of a number: word problems

Learning Objectives Identify the 'whole' and the 'fraction' in a one-step word problem. Represent a word problem using a simple drawing or bar model. Calculate a unit fraction (e.g., 1/2, 1/3, 1/4) of a whole number. Explain that finding a fraction of a number involves division. Solve one-step word problems that require finding a fraction of a whole number. Write a complete sentence to answer a word problem, including the correct units. If you have a pizza with 8 slices and you eat 1/2 of it, how many slices did you eat? 🍕 Let's find out! In this lesson, we will learn how to solve story problems by finding parts of a whole group. This is a very important skill for sharing things fairly, following recipes, and understanding the world around us. Rea...

TermDefinitionExample FractionA number that shows a part of a whole. It has a top number (numerator) and a bottom number (denominator).1/4 is a fraction. It means 'one out of four equal parts'. WholeThe total number of items in a group before you split it into parts.If a problem is about 12 cookies, the 'whole' is 12. DenominatorThe bottom number in a fraction. It tells you how many equal parts the whole is divided into.In the fraction 1/3, the denominator is 3. This means you will make 3 equal groups. NumeratorThe top number in a fraction. For our problems today, it will tell us how many of the equal groups we are interested in.In the fraction 1/3, the numerator is 1. This means we want to know the amount in one of the groups. Unit FractionA fraction where the numerat...

Finding a Fraction of a Number Rule \frac{1}{d} \text{ of } n = n \div d To find a unit fraction of a whole number, you divide the whole number (n) by the denominator (d). The word 'of' tells us to divide. The Denominator is the Divisor \text{Whole Number} \div \text{Denominator} The key to solving these problems is to remember that the bottom number of the fraction (the denominator) is the number you divide by.
