Skip-counting by 100s

The first instance of the Skip counting by 100s exercise is under the Early Math Math Mission. This exercise helps students 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 you will see: This problem begins from a certain number and asks students to select the numbers that they would see if they were to skip-count by hundreds from the given number.Skip100-1.png
 * 2) Fill in skip-count sequence: This problem has the student skip-count by one hundred from a number sometimes forwards and sometimes backwards.Skip100-2.png

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.


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