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?

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

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

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

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 1 4 of the two hexagons.
