Finding 1 on the number line

The topic  is a topic under the 3rd Grade 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 student is asked to move the orange dot to the place where one would be on the number line.Footnl1.png


 * 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. The student is asked to select the point that lies on one.Footnl2.png

Strategies
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).
