In this lesson, we will learn:

- How to find equivalent fractions using models
- How to find equivalent fractions using multiplication (and division)
- How to find fractions in lowest terms (simplest form)

**Equivalent fractions**are fractions with the__same value__even though they look different (top and bottoms are not the same numbers)- This can be proven by showing
**fraction models** - By using the same whole shape and splitting into different numbers of equal parts, all the
**shape models**have the same proportion of shaded area:

- By lining up number lines on top of each other, all the
**number line models**show the dot representing the fractions on the same point along the line

**Equivalent fractions**have the__same value__because they take the same fraction (**proportion**) and**multiply**BOTH the top and bottom by the same number; the__value__does not change

- Fractions in
**lowest terms**(or**simplest form**) are the__smallest equivalent fraction__ **Divide**the top and bottom by the same**common factor**until you can’t anymore

- 1.
**Equivalent fractions on number lines**

Write the equivalent fractions shown on the number line. Use the equal (=) sign in the answer.a)b) - 2.
**Equivalent fractions: fill in the blank**

Write the missing value to make the fractions equal.a)$\large \frac{1}{2}$ = $\large \frac{?}{18}$b)$\large \frac{?}{3}$ = $\large \frac{14}{21}$c)$\large \frac{1}{4}$ = $\large \frac{25}{?}$d)$\large \frac{4}{?}$ = $\large \frac{16}{20}$ - 3.a)$\large \frac{2}{20}$ = $\large \frac{?}{?}$b)$\large \frac{70}{140}$ = $\large \frac{?}{?}$c)$\large \frac{16}{24}$ = $\large \frac{?}{?}$d)$\large \frac{27}{36}$ = $\large \frac{?}{?}$
