Scaling Up and Scaling Down

Front

What does it mean to scale up?

Back

Scaling up refers to increasing the size, amount, or capacity of something, often in a proportional manner.

Front

What does it mean to scale down?

Back

Scaling down means to reduce the size, amount, or capacity of something, often in a proportional manner.

Front

What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, a quantity. It is used to determine how much larger or smaller a figure is compared to another.

Front

If a recipe is scaled up by a factor of 2, what happens to the ingredients?

Back

The amount of each ingredient is doubled.

Front

If a model is scaled down by a factor of 3, how does its size change?

Back

The model's dimensions are reduced to one-third of their original size.

Front

What is the formula for scaling an object?

Back

New Size = Original Size × Scale Factor.

Front

How do you find the new area of a shape when it is scaled up by a factor of 2?

Back

New Area = Original Area × (Scale Factor)². For a scale factor of 2, the area becomes 4 times larger.

Front

How do you find the new volume of a shape when it is scaled down by a factor of 2?

Back

New Volume = Original Volume × (Scale Factor)³. For a scale factor of 2, the volume becomes 1/8 of the original.

Front

What is the relationship between scaling and proportions?

Back

Scaling maintains the proportions of the original object, meaning the shape remains the same even if the size changes.

Front

If a drawing is scaled up by a factor of 5, what happens to the lengths of the lines?

Back

The lengths of the lines are multiplied by 5.
