Understand+a+Fraction

=Overview= The Common Core Math Standards require 3rd grade students to understand a fraction: > 1. 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; > 2. a/b as the quantity formed by parts of size 1/b.

On this wikipage, you will use an Interactive Multimedia Learning Environment to represent fractions.

Learning Context
Imagine that... > 1. You are a 3rd grade student in my classroom > 2. You are in a group of two and have ONE laptop computer in front of you and your partner > 3. You visit our class wikispace (where I would be launching the lesson) - - - http://cogitoandcogitas.wikispaces.com/Whiteboard - - - > 4. You click on the **Math Interactives link** and play with the fraction software in an informal manner (with no directions by me) for about 2 - 3 minutes > 5. When I am ready to begin the lesson, I tell you

Lesson Sequence
Note: This is sequence only asks the students to create one fraction. For a 3rd grade lesson, we would be using this tool at least 3 more times. > 1. Study Figure 1 to see where the sliders,views and fractional representations are located > 2. Click on the following link - @http://illuminations.nctm.org/Activity.aspx?id=3519 - to launch the interactive in a new tab > 3. Use the sliders in the orange region to set the numerator to 6 and the denominator to 9 **(Note: Figure 1 does not show 6/9)** > 4. Change the view from LENGTH to AREA to REGION to SET > 5. Note the different fractional representations of 6/9 > 6. **Reflection:** What do you notice about the numerator and each of the views?
