On the FOURTH day of Math Review my teacher taught to me...

FRACTIONS AND DECIMALS

HOMEWORK

**What is a fraction?**

Parts of a Fraction

What are these parts called?

Naming Fractions

total # of pieces

# of pieces we care about

Name the shaded part of these fractions.

Draw me a fraction that represents 3/4

What is an equivalent fraction?

How do you find equivalent fractions?

Fractions that represent the SAME amount. Equivalent - think EQUAL

Multiply or divide the numerator (top #) and denominator (bottom #) by the same number

What fraction does NOT belong?

Now find a fraction equivalent to 3/7

What about finding an equivalent fraction with a specific numerator or denominator?

Find 3/4 = ?/8.

Be able to explain your steps!

Can you find the equivalent fractions?

Comparing Fractions

If the DENOMINATORS are the SAME, but the numerators are DIFFERENT...

Some examples:

What's the rule?

If the denominator is the SAME, the fraction with the greater numerator is GREATER

If the NUMERATORS are the SAME, but the denominators are DIFFERENT...

Some examples:

What's the rule?

If the numerator is the SAME, the fraction with the greater denominator is SMALLER

For other fractions...

Find equivalent fractions so your fractions have like denominators

OR Use 0, 1/2, and 1 as "benchmarks" to compare.

**What's the connection??**

**The Name Game**

Just a reminder...

Can you TELL me the names of these decimals?
