Subtraction and Pattern Blocks Concepts

The video tutorial explains how to subtract mixed numbers using pattern blocks. It demonstrates representing two and one-third and one and five-sixth with pattern blocks, and the process of subtracting them by exchanging blocks to facilitate the operation. The tutorial concludes by finding the difference and simplifying it to one-half.

What is the initial problem we are trying to solve using pattern blocks?

• Dividing two mixed numbers

• Multiplying two mixed numbers

• Subtracting two mixed numbers

• Adding two mixed numbers

How is the mixed number two and one-third represented using pattern blocks?

• Two yellow blocks and one blue block

• One yellow block and two blue blocks

• Two yellow blocks and one green block

• One yellow block and one blue block

What is the representation of one and five-sixth using pattern blocks?

• Two yellow blocks and five green blocks

• Two yellow blocks and one green block

• One yellow block and one blue block

• One yellow block and five green blocks

Why do we need to perform exchanges during the subtraction process?

• To add more pattern blocks

• To have enough green blocks to remove

• To change the color of the blocks

• To simplify the subtraction

What is the equivalent of one-third in terms of sixths?

• Three-sixths

• One-sixth

• Four-sixths

• Two-sixths

What is the first step in performing the subtraction after exchanges?

• Remove one yellow block

• Add more yellow blocks

• Remove one blue block

• Remove five green blocks

After removing the necessary blocks, what is the remaining number of green blocks?

• One green block

• Two green blocks

• Three green blocks

• Four green blocks

What is the simplified form of the difference found using pattern blocks?

• One-third

• One-half

• Two-thirds

• Three-fourths

What is the common factor between the numerator and denominator of three-sixths?

• Four

• Five

• Two

• Three

What is the final equivalent difference of two and one-third minus one and five-sixth?

• One-third

• One-half

• Three-fourths

• Two-thirds
