To draw two models representing the concept of "3-fourths" (3/4) while ensuring they do not represent the same amount, you can use the following methods:
### Model 1: Circle Model
1. **Draw a Circle**: Start by drawing a large circle.
2. **Divide into Equal Parts**: Divide the circle into 4 equal sections (like slicing a pizza).
3. **Shade 3 Parts**: Shade in 3 out of the 4 sections. This represents 3/4 of the circle.
### Model 2: Rectangle Model
1. **Draw a Rectangle**: Next, draw a rectangular shape, such as a rectangle that is wider than it is tall.
2. **Divide into Equal Parts**: Divide the rectangle into 4 equal vertical strips.
3. **Shade 3 Parts**: Shade in 3 out of the 4 strips. This also represents 3/4 of the rectangle.
### Ensuring They Do Not Represent the Same Amount
While both models represent "3-fourths," they do not represent the same area because the dimensions of the circle and the rectangle are different. Depending on the size of the rectangle compared to the size of the circle, the total areas can differ.
### Important Note
The area calculations show that two shapes (like a circle and a rectangle) can have the same fractional representation of their respective parts but still have different total areas, clearly demonstrating that they are not the same despite both showing 3/4. For example, if the circle has a radius and the rectangle has length and width, the areas will differ, thus reinforcing the concept.
