Things to Consider When Adding Two Three-Digit Numbers - Now that you have come so far, playing around with the numbers and adding and subtracting them. It's time to switch things up and move to the next step. But what is the next step? Well, the next step is pretty much like the first step but with greater numbers. The addition is the mathematics first operation we learn about as kids. As you move up the ladder of addition, the operation becomes a little bit more complicated, and you get two and three digits to work with. If that's intimidating you, let's learn about a few things to consider when adding two-three-digit numbers. The first thing to consider is to place the digits on one another. Place ones on ones, tens on tens and hundreds over hundreds. Start adding from the left. If the answer is two digits, place the ten above the next ten place column and add it when adding that column. Repeat the same for hundreds. For the last column, which is on the right corner, write the answer completely. These lessons and worksheets help students learn to find the sum of triple digit numbers.



Homework Sheets

These are somewhat of a single serving topic.

  • Homework 1 - Well spaced and has a great deal of room to go further.
  • Homework 2 - A nice and solid set of triple digits.
  • Homework 3 - Equally separating these integers is key.



Practice Worksheets

Everything follows a direct path. You will find the varying use of higher numbers to be more challenging here.

  • Practice 1 - These values are tightly packed.
  • Practice 2 - The comma does not appear in the final value to all them to align.
  • Practice 3 - Don't get confused by what is being presented here.



Math Skill Quizzes

These problems mimic exactly what you can expect a state assessment.

  • Quiz 1 - See how well you can do these.
  • Quiz 2 - What do you need to do to add these up.
  • Quiz 3 - I was wishing you would look at this one last.
