A ratio is a relationship that exists between the amounts of TWO NUMBERS (example: 3 to 4; 3 : 4; fractional form ).

OUTCOMES:
1. Explain that equivalent fractions represent the same quantity. (gr5 POS)
2. Use a mathematical rule for developing a set of equivalent fractions. (gr5 POS)
3. Express a given fraction as a reduced (simplified) fraction in lowest terms (or simplest form) by
identifying the common factor shared with both the numerator and denominator (gr7 POS).
4. Explain why simplifying a fraction does not change the ‘value’ of the fraction.
MATERIAL NEEDED: highlighters, pencil, blue pen, ruler
***CREATING EQUIVALENT FRACTIONS IS A LIFE SKILL!!!
***we are REDUCING (or called SIMPLIFYING) FRACTIONS
which is A LIFE SKILL!!!
*** NOTE: The more familiar you are with your 12X tables, the easier this is to do!
***NOTE: The faster you learn to identify these patterns, the easier this is to do! YOU MUST KNOW and
LEARN HOW TO REDUCE FRACTIONS! Not optional.
Example #1: Find equivalent fractions by REDUCING TO LOWEST TERMS (also called simplest form).
STRATEGY: LOOK AT THE LAST DIGIT IN THE NUMERATOR AND THE DENOMINATOR…
