Agenda: Adding Fractions

1/10

1.) Already have a common denominator. 2.) Add the top fractions straight across. Ex: 3+6 = 9 3.) 9/12... now SIMPLIFY. 4.) The numerator and denominator can be divided by 3 so you get 3/4.

3/12 + 6/12 = 3/4 because...

True or False:

Good Job! The numerators do NOT NEED to be the same when adding fractions.

Adding fractions is about adding parts, and the "parts" of a fraction are the numerator. The numerator likely won't be the same every time!

Good Job! The numerators do NOT NEED to be the same when adding fractions because...

3/10

10/12 is equivalent to 5/6 because 5x2 is 10 and 6x2 is 12. The quantity is the same across both fractions!!

4/10

Good Job!! The denominators DO have to be the SAME when adding fractions!

The denominator represents the quantity. You want to add "like" parts or parts with the same number of equal parts.

Good Job!! The denominators DO have to be the SAME when adding fractions BECAUSE...

You don't have to change mixed numbers into improper fractions, but it is easier to add and subtract if they are in improper form.

Today you reviewed your knowledge on: 1.) Adding fractions & simplifying 2.) Numerators 3.) Denominators 4.) Equivalent fractions 5.) Mixed numbers 6.) Improper fractions!

Conclusion and Review:

Thanks for learning about fractions!
