Understanding Base 10 Blocks

This video tutorial teaches how to use base 10 blocks to identify and express numbers. It begins with an introduction to the different types of base 10 blocks: ones cubes, tens rods, and hundreds flats. The tutorial then demonstrates how to use these blocks to identify numbers by drawing a place value chart and counting the blocks. It provides examples, such as identifying the number 123 and expressing the number 211 using base 10 blocks. Additionally, it explores alternative ways to represent numbers, emphasizing that different visual models can represent the same numerical value.

What does a single cube represent in base 10 blocks?

• One thousand

• One ten

• One hundred

• One one

How many ones cubes are needed to form a tens rod?

• 20

• 5

• 15

• 10

In the number 123, how many tens rods are there?

• 1

• 2

• 4

• 3

What is the hundreds digit in the number 123?

• 3

• 1

• 2

• 0

How many hundreds flats are needed to represent the number 211?

• 2

• 4

• 1

• 3

In the number 211, what does the tens place represent?

• 3 tens

• 0 tens

• 1 ten

• 2 tens

How many ones cubes are used in the alternative representation of 211?

• 11

• 1

• 5

• 10

What is the alternative way to represent the number 211 using base 10 blocks?

• Two hundreds flats and one hundred ones cubes

• Two hundreds flats and eleven ones cubes

• Two hundreds flats and one tens rod

• One hundred flat and eleven tens rods

What is the visual difference between representing 211 as one ten and one one versus eleven ones?

• One uses fewer blocks

• There is no visual difference

• One is more colorful

• One uses more blocks

What is the main takeaway from using base 10 blocks to represent numbers?

• They are only useful for small numbers

• They help visualize place value

• They are not useful for learning

• They are only for advanced math
