Exercise Name: Finding 1 on the number line
Math Missions: 3rd grade (U.S.) Math Mission
Types of Problems: 2

The topic Finding 1 on the number line is a topic under the 3rd grade (U.S.) Math Mission. This exercise connects the idea of division as an inverse operation to multiplication.

Types of Problems

There are two types of problems in this exercise:

  1. Move the dot to the correct spot: This problem has a number line and a movable orange dot. The user is asked to move the orange dot to the place where one would be on the number line.

    Move the dot to the correct spot

  1. Select the dot that marks one: This problem has a partially marked number line and several blue dots. One of the blue dots represents the number one. Users are asked to select the point that lies on one.

    Select that dot that marks one


Fraction knowledge and a visual or geometric understanding of numbers can help perform this problem, but are not absolutely necessary.

  1. The ticks marks are conveniently spaced out so the dot will be at a tick mark.
  2. Practicing with the number line can increase aptitude with arithmetic, and one is an important number in mathematics (the multiplicative identity).

Real-life Applications

  1. Fractions appear in every-day media to display information to consumers.
  2. Fractions are used in real life in many different ways, but they are most commonly used in the cooking, construction and science industries.
