Session 1.6 - Combinations That Equal 1
Learning Goals -
1. I can use representations to add fractions that sum to 1.
2. I can add fractions with the same and related denominators (e.g., halves, fourths, and eighths; thirds and sixths)
2. I can add fractions with the same and related denominators (e.g., halves, fourths, and eighths; thirds and sixths)
Introduction to Adding Fractions
1/2 + 2/6 = 5/6
Is this equations true? Show how you know.
Is this equations true? Show how you know.
1/2 + 2/6 + 1/2 =
What if we add another 1/2?
Now what is the sum?
What if we add another 1/2?
Now what is the sum?
How can you show 1/2 + 2/6 + 1/2 on these 4 X 6 rectangles? What if we thought about boxes like those you see in the supermarket with 24 apples in each box? What would 1/2 + 2/6 + 1/2 of boxes of apples look like?
Fractions/Adding Fractions
Use what you know about fractions to make representations (models or pictures) of how to show the fractions related to a whole.
