Understanding Fraction Subtraction with Pattern Blocks

The video tutorial explains how to subtract fractions using pattern blocks. It begins by defining the value of each pattern block and demonstrates subtracting one-sixth from one-half. The process involves exchanging pattern blocks to show equivalence and simplifying the result from two-sixths to one-third. An alternative method using overlay is also presented to illustrate the subtraction.

What does a yellow pattern block represent in the video?

• One-sixth

• One-third

• One-half

• One whole

How many green pattern blocks are equivalent to one red pattern block?

• One

• Four

• Three

• Two

What is the result of subtracting one-sixth from one-half using pattern blocks?

• One-sixth

• Two-sixths

• One-third

• Three-sixths

What is the simplified form of two-sixths?

• One-half

• One-sixth

• One-third

• Three-sixths

What does the video demonstrate about equivalent fractions?

• They are not useful in subtraction.

• They are always greater than the original fraction.

• They have different values.

• They represent the same value in different forms.

How can two green pattern blocks be exchanged in the video?

• For one blue pattern block

• For one red pattern block

• For one yellow pattern block

• For one green pattern block

What is the alternative method shown for subtracting one-sixth from one-half?

• Using a number line

• Drawing a diagram

• Overlaying pattern blocks

• Using a calculator

What is the equivalent of one blue pattern block?

• One-sixth

• One-half

• One-third

• One whole

What is the final result of the subtraction shown in the video?

• Two-thirds

• One-half

• One-sixth

• One-third

What is the purpose of using pattern blocks in the video?

• To show different colors

• To make the video colorful

• To visually demonstrate fraction subtraction

• To confuse the viewer
