Subtraction Using Base-Ten Blocks with Regrouping (Example)

The video tutorial demonstrates how to subtract 95 from 381 using base 10 blocks. It begins by setting up the problem with units, rods, and flats representing the numbers. The process involves borrowing from higher place values to subtract in the ones and tens places, ultimately arriving at the solution of 286.

What is the first step in representing the number 381 using base 10 blocks?

• Place 3 rods in the tens place.

• Place 8 flats in the hundreds place.

• Place 1 unit in the ones place.

• Place 5 units in the ones place.

How many units do we have in the ones place after borrowing from the tens place?

• 5 units

• 11 units

• 9 units

• 10 units

What do we do when we need to subtract 9 rods from 7 rods in the tens place?

• Borrow 1 flat from the hundreds place.

• Borrow 1 flat from the tens place.

• Borrow 1 rod from the tens place.

• Borrow 1 unit from the ones place.

After borrowing from the hundreds place, how many rods do we have in the tens place?

• 12 rods

• 17 rods

• 15 rods

• 10 rods

What is the final difference after completing the subtraction 381 - 95?

• 286

• 196

• 295

• 276
