Subtraction of Four-Digit Whole Numbers Using Base Ten Blocks

This video tutorial demonstrates how to subtract four-digit whole numbers using base ten blocks. It uses the example of subtracting 1627 from 4352, illustrating the process through modeling with online base ten blocks. The tutorial covers subtraction in the ones, tens, hundreds, and thousands place values, emphasizing the need for exchanges when there are insufficient units, rods, or flats. The final result of the subtraction is 2725.

What is the initial model for the number 4352 using base ten blocks?

• 4 cubes, 5 flats, 3 rods, 2 units

• 4 cubes, 3 flats, 5 rods, 2 units

• 4 cubes, 3 flats, 2 rods, 5 units

• 3 cubes, 4 flats, 5 rods, 2 units

Why do we need to perform an exchange in the ones place value?

• To add more units

• To remove more units than available

• To change the color of units

• To increase the number of rods

After exchanging one rod for 10 units, how many units do we have in total?

• 12 units

• 15 units

• 10 units

• 7 units

What is the result in the ones place value after removing 7 units from 12 units?

• 5 units

• 3 units

• 7 units

• 0 units

How many rods are left after removing 2 rods from 4 rods in the tens place value?

• 4 rods

• 1 rod

• 2 rods

• 3 rods

What exchange is performed in the hundreds place value to facilitate subtraction?

• One rod for 10 units

• One cube for 10 flats

• One cube for 10 rods

• One flat for 10 units

How many flats are left after removing 6 flats from 13 flats?

• 7 flats

• 6 flats

• 5 flats

• 8 flats

What is the final step in the subtraction process?

• Removing one cube from three cubes

• Exchanging one rod for 10 units

• Adding one cube to three cubes

• Exchanging one cube for 10 flats

What is the final difference after completing the subtraction?

• 2752

• 2725

• 2572

• 2735

How many cubes are left in the thousands place value after subtraction?

• 4 cubes

• 3 cubes

• 1 cube

• 2 cubes
