Students start with a review. We talk about how fractions are a part of a whole. We also look at how we can use fraction circles, fraction bars, numbers lines, and sets to represent fractions.
This video reviews what a denominator and a numerator represent.
This video reviews how to represent fractions using sets.
This video reviews how to represent fractions using fraction circles, number lines, and fraction bars.
Next, we learn how to create equivalent fractions (meaning fractions of the same size) using three methods:
with hands-on manipulatives,
with pictures (fraction bars, number lines, and fraction circles), and
using multiplication.
Method 1:
This video goes over how we can use hands-on fraction tiles to create equivalent fractions.
Method 2:
This video goes over how we can use picture models of fraction bars and circles to create equivalent fractions.
Method 3:
This video goes over how we can use multiplication to create equivalent fractions.
Next, we learn how to compare and order fractions using two methods:
with hands-on manipulatives and pictures (fraction bars, number lines, and fraction circles), and
using cross multiplication.
Method 1:
This video goes over how we can use fraction bars to create compare fractions.
Method 2:
This video goes over how we can use cross multiplication to compare fractions.
Students start with a review. We talk about how fractions are related to division. We divide the numerator by the denominator we get a decimal. We review this on our calculators first.
We can use fractions that have denominators of 10, 100, 1000 to find decimals easily using place value and pictures.
Method 1:
This place value chart helps us convert fractions to decimals.
Method 2:
We can use pictures to help us relate fractions to decimals.
We will use place value, benchmarks, and equivalent decimals to compare and order decimals.
First, we need to understand the place value of decimals.
It's also very helpful to understand what equivalent decimals are.
Comparing Decimals:
We can use place values and equivalencies to compare decimals.
