Types of Problems

    Move the dot to the right spot


Since this problem is on the number line, experience with the number line is helpful. Being able to skip-count by single digit-numbers may be helpful but is not required.

  1. There are ten tick marks on the number line, this can be used to plot the points more quickly.
  2. The halfway mark is just beyond the end of the "question" which helps to estimate the middle point.
  3. The solution will always lie directly on one of the tick marks.

Real-life Applications

  1. Counting is essential for shopping, so people can count how many dollars they have and see if they have enough to purchase something.
  2. Fractions, decimals, and percents are used in many sports such as basketball to determine how many field goals the player has made over how many they attempted.
  3. Fractions are used in real life in lots of different ways, but are commonly used in cooking, construction and science.
