Mastering 2-Digit by 1-Digit Multiplication Strategies

The video tutorial covers the concept of multiplying two-digit by one-digit numbers, specifically using the example of a softball team paying for tournaments. It explains the standard algorithm, the distributive property, and alternative methods like compensation. The tutorial is based on a third-grade math standard from Texas and uses a problem from a 2021 test. The video encourages students to try solving the problem independently before reviewing the solutions together.

What is the cost per tournament for the softball team?

• $95

• $105

• $90

• $100

What is the first step in the standard algorithm for multiplication?

• Subtract the numbers

• Add the numbers

• Multiply the ones place

• Multiply the tens place

What do you do with the carry-over number in the standard algorithm?

• Divide it

• Ignore it

• Add it to the next multiplication

• Subtract it

What is the result of 95 times 6 using the standard algorithm?

• 590

• 580

• 560

• 570

Which method uses the concept of 'carrying over' in multiplication?

• Compensation method

• Estimation method

• Distributive property

• Standard algorithm

How does the distributive property simplify multiplication?

• By subtracting numbers

• By breaking numbers into smaller parts

• By dividing numbers

• By adding numbers

What is the result of 90 times 6 in the distributive method?

• 540
