The Numbers to 100 exercise appears under the Early math Math Mission. This exercise helps students to understand the naming and relationship patterns among numbers that are less than or equal to 100.


Types of problems

There are four types of problems that show up in this exercise:

  1. Select the missing number 1-100: This problem shows a grid with a missing number and three possible answer choices below. The KA user is to select the number that would go in the missing box.
  2. Enter the missing number 1-100: This problem shows a grid with a missing number and an entry box in which students are to type the missing number. Repeated testing of this exercise yielded only one problem of this type. The answer to that problem was 72.
  3. Select the missing number 1-100, intervals of ten: This problem give a sequence of colored multiples of ten with one of the numbers missing. The problem has three possible answer choices below and the missing number from the sequence is to be selected from among those three possible answers.
  4. Put the numbers in order: This problem has eleven consecutive numbers, starting and ending with a multiple of ten, that are to be slid into the correct order. There is one exception where there are only ten numbers, the exercise of ordering 1 through 10. Through testing this problem takes longer than 4 seconds to accomplish on average, making this exercise a difficult one for speed badges at this time.


  1. The first three problem types are straightforward and can be accomplished quickly for accuracy badges and speed badges. The fourth one cannot be done very quickly at this time, but is still straightforward with knowledge of the numbering system.

Real-life Applications

  1. Knowing how to count is essential for learning algebra and the higher maths.
  2. The whole world evolves around numbers and counting.
