Fractions

Lesson objectives:
1) I can identify the parts of a fraction.
2) I can compare fractions with the same numerator or the same denominator.
_________________________________
Anticipatory Set:
Review the parts of a fraction, Numerator and Denominator.
Ask the following questions:
> If I had a box of 24 cookies and I shared them with one friend how many would we each get? (12 cookies, explain since there's two people we'd each get 12.)
> If I had a box of 24 cookies and I shared them with two friends how many would we each get (8 cookies)
> If I had shared them with three friends how many would we each get? (6 cookies)
> If I had a shared them with five friends how many would we each get? (4 cookies)
> If I shared them with seven friends how many would we each get? (3 cookies)
> If I shared them with eleven friends? (2 cookies)
> If I gave a cookie to everyone in the class, but I didn't get one....(1 cookie)
Ask students how many they'd like to have.
> What did you notice when we added people?
> Explain the people were the "whole"

Use the Doodle Pro app to draw fractions to compare.
> Explain that when the denominator is the same you look for the LARGER numerator.
> Explain that when the numerator is the same you look for the SMALLER denominator.
> Show the Khan Academy video on comparing fractions.
> Break out into partners to complete comparing fraction flash cards.

Pull Small Group (students with IEPs, low math scores)
~ Students have the iTooch app that was purchased through school funds. Parent club has also purchased a set of headphones for each iPad mini)
> Continue to use examples on the iPad mini with Doodle Pro, allow students to also draw the fractions
> Use iTooch Math: Grade 3 as another reinforcement.
> This will provide at level math instruction in a fun and engaging way.
> Students will complete the task cards in a small group.

The students who were pulled for the small group will then use the iPad mini to work on fact fluency

Closing:
Use the Socrative app to assess students on their knowledge of comparing numbers with like numerators or like denominators.
