2. Lesson Opening
Using your pattern blocks, answer the following questions:
How many green triangles are in one blue rhombus?
How many blue rhombuses are in one yellow hexagon?
How many red trapezoids are in one yellow hexagon?

3. Lesson Opening
Using your pattern blocks, answer the following questions:
How many green triangles are in one blue rhombus?
How many blue rhombuses are in one yellow hexagon?
How many red trapezoids are in one yellow hexagon? 2

4. Lesson Opening
Using your pattern blocks, answer the following questions:
How many green triangles are in one blue rhombus?
How many blue rhombuses are in one yellow hexagon?
How many red trapezoids are in one yellow hexagon? 2 3

5. Lesson Opening
Using your pattern blocks, answer the following questions:
How many green triangles are in one blue rhombus?
How many blue rhombuses are in one yellow hexagon?
How many red trapezoids are in one yellow hexagon? 2 3 2

6. So, the triangle is 1 2 of the rhombus.
If 2 green triangles are in 1 blue rhombus…
Then, the green triangle is what FRACTION of the blue rhombus?
1 2
1 2
The green triangles represent 2 EQUAL PARTS, or 2 halves of the blue rhombus.
So, the triangle is of the rhombus.
