More or Less: Comparing Sums of Two-Digit Addition Problems

Let's take a minute to look at the ideas of "less than", "greater than", and "equal to". Throughout math, you will be comparing two values. You will need to understand that one is greater, less, or equal to the other. A number is "less than" when it is smaller. A number is "greater than" when it is larger. Numbers are equal when they have the same values.

This activity compares the sums of two addition problems. Your first step will be to solve the problems and then you need to compare the sums. This activity adds two-digit numbers that use carrying. Here's an example:
48 + 13 = 61
37 + 25 = 62
When you compare the sums you will see that sixty-one (61) is less than sixty-two (62). So the answer would be:
48 + 13 is less than 37 + 25 OR 48 + 13 < 37 + 25

Good luck and have fun.

Directions

This type of activity challenges you to compare two values. You will be asked which value is greater or smaller for each question. Compare the two choices and click one of the center buttons. Those buttons will offer you the options of "Less Than", Equal To", and "Greater Than." Just click on the button with the correct answer. The next screen will show you the right answer.

You get a happy face for every correct answer and a sad face for every wrong answer. The quiz is over after ten (10) questions. Take the quiz again and again because all of the questions are random. Chances are, you'll get a new quiz every time. It's good practice to learn these basic arithmetic comparisons.
