The number icons are called Module Numbering and within every course there are variations of modules, lessons and activities. Modules are like chapters that contain lessons and the lessons contain activities.
Below is an example side menu of Creating Justice, which has 6 modules and are numbered 1-6.
If we open up module 1, in Creating Justice, we will find module 1 has 6 lessons, which will be numbered with module 1’s number shown in front of the lesson’s number.
Shown below, module 1, lesson 1, number icon is listed as 1.1.
Now, if you open up lesson 1, in Creating Justice, you will find it has 8 activities and you will find module 1’s and lesson 1’s numbering shown in front of the activity’s number.
Example below, you will see the number icon 1.1.4, which means module 1, lesson 1, activity 4.
If you open activity 4, in Creating Justice, and you will see numbered pages listed below the activity. These are numbered pages do not contain module numbering, as seen below.
NOTE: Every course is structured differently, while Creating Justice has 6 modules with many lessons and activities; Understanding Racism has 1 module with many lessons and activities.
