Understanding Base 10 Blocks

The video tutorial explains how to use base 10 blocks to model whole numbers. It begins by defining the unit as one small square or cube, then introduces rods and flats, which represent 10 and 100 units respectively. The tutorial provides examples of modeling numbers 257 and 613 using these blocks, demonstrating how to express these numbers in expanded form.

What is the unit defined as in the context of base 10 blocks?

• A large cube

• A small square or cube

• A rod

• A flat

How many units make up a rod in base 10 blocks?

• 50 units

• 20 units

• 10 units

• 5 units

In the first example, how many flats are used to model the number?

• 3 flats

• 2 flats

• 4 flats

• 1 flat

What is the expanded form of the number 257 using base 10 blocks?

• 200 + 50 + 7

• 100 + 50 + 7

• 200 + 70 + 5

• 100 + 70 + 5

In the second example, how many rods are used to model the number?

• 2 rods

• 4 rods

• 1 rod

• 3 rods

What is the expanded form of the number 613 using base 10 blocks?

• 500 + 30 + 1

• 600 + 30 + 1

• 500 + 10 + 3

• 600 + 10 + 3

How many flats are used in the second example to model the number?

• 7 flats

• 5 flats

• 4 flats

• 6 flats
