Multiplication Split Strategy

The video tutorial introduces a strategy for solving multiplication problems by splitting larger numbers into smaller parts. It demonstrates this method with examples, such as 7 times 43 and 4 times 627, by breaking down the numbers into tens, hundreds, and ones, multiplying each part separately, and then adding the results. The tutorial concludes with practice problems for viewers to try using the split strategy.

What is the first step in the split strategy for multiplication?

• Add the numbers together.

• Split the larger number into tens and ones.

• Subtract the smaller number from the larger number.

• Multiply the numbers directly.

When using the split strategy, what do you do after multiplying each part?

• Multiply the results together.

• Add the results together.

• Subtract the smaller result from the larger result.

• Divide the results by 2.

In the example of 7 times 43, what is the result of multiplying the tens part by 7?

• 280

• 301

• 43

• 21

How do you handle the hundreds place when using the split strategy on a number like 627?

• Add it to the tens and ones.

• Multiply it by the other number and add zeros.

• Subtract it from the tens.

• Ignore it and focus on tens and ones.

What is the final result of multiplying 4 by 627 using the split strategy?

• 2528

• 6270

• 2508

• 2400
