Description
Exercise Name: Skip-counting by 100s
Math Missions: Early math Math Mission
Types of Problems: 2

The first instance of the Skip-counting by 100s exercise is located in the Early math Math Mission. This exercise helps users to understand the patterns of the numbers that are one hundred apart both forwards and backwards from a starting point.

Types of problems

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

  1. Select those users will see: This problem begins from a certain number and asks users to select the numbers that they would see if they were to skip-count by hundreds from the given number.
    Skip100-1

    Select those users will see

  2. Fill in skip-count sequence: This problem has the user skip-count by one hundred from a number sometimes forwards and sometimes backwards.
    Skip100-2

    Fill in skip-count sequence

Strategies

These problems seem easy to get accuracy badges but because of the multiple select and multiple fill-ins they are medium difficulty to get speed badges. Using the "tab" button can make these problems faster.

  1. When users skip count by 100, there is only one option for the tens and the ones digit. If they can figure out what they are it is easier to find the correct solutions on problem type one, and easier to check their answers on problem type two.

Real-life Applications

  1. Knowing how to count is essential for learning algebra and the higher maths, and counting is used for almost everything humans do.
