v. 19

Week 19: Lesson 1: Adding and Subtracting Fractions

In this lesson, we will review the parts of a fraction.

Fraction - bråk

Numerator (top number) - täljare

Denominator (bottom number) - nämnare

We will also look at adding and subtracting numbers with common denominators. Common denominators mean that the number on the bottom of two or more fractions is the same. e.g. 2/4 and 3/4. The common denominator is 4.

When adding fractions with common denominators, simply add the numerators to find the answer. e.g. 1/5 + 2/5 = 3/5

The rule is the same when subtracting fractions. e.g. 4/5 - 3/5 = 1/5

Week 19: Lesson 2: Equivalent Fractions and Operations

In this lesson, we will review a range of terms such as factors, multiples, and equivalent fractions. We will use this knowledge to find equivalent fractions.

We will also look at how to add and subtract fractions when they do not have a common denominator.

$Image result for adding and subtracting fractions$

First, find the Lowest Common Multiple (the smallest multiple that the denominators share)

Multiply (or divide) the numerator by the same number so that it stays equivalent to the original fraction.

Then, add or subtract the new fractions using the same steps as last lesson.

Week 19: Lesson 3: Word Problems

In this lesson, we will be solving word problems to do with adding and subtracting fractions.

v. 20

Week 20: Lesson 1: Order of Operations

In this lesson, we will introduce using the order of operations to solve questions.

Example:

First we solve what is inside the Brackets

48 / 2 (9+3)

= 48 /2 (12)

Then we multiply

= 48 / 2x(12)

= 48 / 24

Then we divide

48/24

= 2

Week 20: Lesson 2: Order of Operations

In this lesson, we will review the terms for BEDMAS. We will also practise solving more questions using the correct order of operations.
