Make number lines active!

Number lines don’t have to be a printed worksheet. Our Open Number Line floor mat is a versatile tool and turns addition and subtraction into several movement-based activities. This mat helps young students learn counting, addition, subtraction, rounding, ordering numbers, skip counting, fractions, decimals, and more! It is suitable for both elementary and middle school students.

This open number line includes 20 equidistant hash marks. These marks can be labelled with anything to fit your individual activity needs. You can use 1 through 20 for basic counting, addition, and subtraction practice, multiples of 10, 0 to 1 for fractions (e.g. “0” on the first line and “1” on the sixth lines for sixths, etc), and more.

Measuring 26 inches wide and 130 inches long, this open number line mat has plenty of space for multiple students to hop on. After hopping on this blank number line, students will have improved addition, subtraction, counting, rounding, ordering, and more math skills.

Movement-based activities will boost learning comprehension while helping young students develop gross motor skills. Whether using it for math class or during free time, this mat will encourage active learning and collaborative play. Take a look at our activity database for more activities and sensory play to keep your students on their feet.

Sample Activity: Thermometer

  • First, use the number line vertically to represent a thermometer.
  • Next, label every five marks with a multiple of ten, using the outdoor temperature as your range.
  • For example, If it is 76 degrees outside, label the bottom of the thermometer 60, 70 at the fifth mark, and 80 at the tenth mark.
  • Then, have students figure out how many each hash mark is representing (in this case, two degrees.)
  • Finally, have the students place a bean bag (or any marker) to show 76 degrees.
  • Choose other temperatures between 60 and 80 or change the range and space between temperatures for more practice
