How many blue rhombuses are in THREE yellow hexagons?
How many green triangles are in FOUR blue rhombuses?

3. Lesson Opening
Using your pattern blocks, answer the following questions:
How many red trapezoids are in TWO yellow hexagons?
How many blue rhombuses are in THREE yellow hexagons?
How many green triangles are in FOUR blue rhombuses? 4

4. Lesson Opening
Using your pattern blocks, answer the following questions:
How many red trapezoids are in TWO yellow hexagons?
How many blue rhombuses are in THREE yellow hexagons?
How many green triangles are in FOUR blue rhombuses? 4 9

5. Lesson Opening
Using your pattern blocks, answer the following questions:
How many red trapezoids are in TWO yellow hexagons?
How many blue rhombuses are in THREE yellow hexagons?
How many green triangles are in FOUR blue rhombuses? 4 9 8

6. So, one trapezoid is 1 4 of the two hexagons.
If 4 red trapezoids are in 2 yellow hexagons…
Then, a red trapezoid is what FRACTION of TWO yellow hexagons?
1 4
1 4
1 4
1 4
The red trapezoids represent 4 EQUAL PARTS, or 4 fourths of the two yellow hexagons.
So, one trapezoid is of the two hexagons.
