Comparison of numbers


  • To learn to compare numbers
  • Reading, writing, and comparing one- and two-digit numbers;
  • “+”, “-“, “=”, “>”, “<” use of symbols.

This virtual activity is designed for use in math lessons on the following topics:

  • Grade 1. “Comparing groups of things”
  • Grade 1. “Comparing numerical expressions”
  • Grade 2. “Comparison of two-digit numbers”

Theoretical part

Comparing numbers is an activity that helps to determine which of two numbers is larger and which is smaller.

Compare numbers by their place in the series of natural numbers.

Compares two-digit numbers by digit, starting with the second (decimal) digit. If the number of decimals is the same, the units compare the digits.

We compare numbers using comparison signs:

  • We use “>” (greater than) and “<” (less than) signs to show which number is greater and which is less. For example, 5 > 3 means that 5 is greater than 3.

Virtual experiment

The “comparing numbers” simulation allows students to become familiar with and compare numbers. The numbers and pictures allow for flexibility in learning about comparison.


Part 1. Comparison

Step 1. Start the simulation: you will be given 2 different modes, “Compare” and “Lab”. Open the “Compare” section.

Step 2. Work area:

  • Windows for comparing results.
  • Two windows to place the items (puppy, apple, butterfly, ball, number) and compare them.
  • A table to organize the items placed in the windows.
  • Comparison can be seen in the form of cubes and segments.
  • Reset button.

Step 3. Place the puppy by holding down the left mouse button in window 1 for placing items.

Step 4. In the windows above, you will see the result of the comparison: 1>0.

Step 5. You can increase and decrease the number of items in the windows by using the buttons next to the object.

Step 6. Place some puppies in the second window. Compare the comparison expression and the cube column.

Step 7. Change the column of cubes to a segment type and observe the changes. Use a table so that the puppies are arranged in sequence.

Step 8. Make several comparisons by placing the puppy in two windows to place items of different quantities.

Step 9. Make comparisons by replacing the puppy with other types of objects (such as a butterfly or a number).

Part 2. Lab part

Step 10. Open the “Lab” section. In the work area, you are provided with:

  • Numbers from 1 to 20;
  • Operations: comparison, equals, addition, subtraction;
  • Table, puppy, apple, butterfly, ball, number;
  • Reset button.

Step 11. Using the puppy and operations, create a comparison expression.

Step 12. Compare the expression you created with the numbers at the top of the screen.

Step 13. Additional Assignments:

  • In the lab portion, you can optionally compose different expressions using the elements provided and reinforce your knowledge of comparison.
  • Create several types of expressions using different numbers, operations, and items.


Students learned how to compare numbers using virtual tools and modeling. The fact that the comparisons were not only in the form of numbers but also in the form of different objects made it easy for the students to understand the subject matter. This experience enriched the knowledge of mathematics and will come in handy in future learning experiences.
