Using the Partial Sums Method to Solve Addition Problems

The video tutorial explains the partial sums method for addition, which involves breaking numbers into expanded form to simplify the addition process. It demonstrates this method with examples, including a real-world scenario of calculating travel distances. The partial sums method is highlighted as a useful strategy for checking work and solving addition problems mentally.

What is the purpose of rewriting numbers in expanded notation?

• To convert them into fractions

• To make them easier to subtract

• To show the value of each digit

• To make them look more complex

In the partial sums method, what is the first step when adding two numbers?

• Break down the numbers into their parts

• Multiply the numbers together

• Subtract the smaller number from the larger one

• Convert the numbers into decimals

How do you keep track of the addition process in the partial sums method?

• By using a calculator

• By drawing a diagram

• By writing down each partial sum

• By memorizing the numbers

When solving a real-world problem using the partial sums method, what is a recommended strategy?

• Ignore the expanded form

• Start with the smallest values

• Add all numbers at once

• Start with the largest values

What was the total distance Natalie traveled using the partial sums method?

• 3000 miles

• 682 miles

• 1367 miles

• 2049 miles
