Color code and lesson validation

What do the colors correspond to? Do I need to assign red lessons?

Lesson Validation

In order to validate a lesson, students need to have completed a minimum number of exercises (which varies depending on the lesson), and to have given correct answers in their more recent attempts.
Validated lessons correspond to the green tiles on the Lesson Progress tab, and to the green stars in the Answer Reports.

The 'Lesson Progress' dashboard

Each tile of the Dashboard corresponds to a lesson. These tiles can be:

  • Striped tiles, meaning that the lesson was validated during the placement test;

  • Gray tiles framed in blue, meaning that the students have started working on these lessons;

  • Red tiles, meaning that the students are having trouble validating the lesson;

  • Green tiles, meaning that the students have worked on and validated these lessons.

    • Lessons with a tick mark correspond to validated lessons;

    • Lessons with a R correspond to validated lessons which were later automatically reviewed. (Even if the student did not succeed at the review, the tile stays green and shows an R instead of the checkmark.)

  • Blue triangles correspond to assignments.

Students will automatically return to practice red and blue lessons after practicing other skills, so you don't need to assign these lessons.

In the Answer Report

  • Lessons are gray when students have not completed enough exercises yet for Lalilo to determine whether they are struggling or doing great;

  • Lessons are red when students are struggling; they have answered a lot of questions, but the majority of answers are wrong.

  • Lessons are green when students have answered enough questions properly for Lalilo to know that they have validated the skill that corresponds to the lesson.

You can click on each instruction to see your student's replies, and you can access the exercise by clicking on View Exercise on the right:

Success rates for instructions are:

  • Green for results >80%

  • Orange for results <80%

  • Red for results <50%


When students work on Lalilo, they first take a placement test that places them at a starting lesson on Lalilo. Then, they work their way through our lesson progression. They work on more than one lesson at a time. They may have 3-7 open lessons that they work on at once.

You can reassign validated lessons (and any lesson) from the assignments button in your dashboard. This will take students out of the Lalilo lesson progression as they complete assignments. Once the assignment is completed, they will go back to where they had left off in the progression.
​
You can check our scope and sequence under the resources tab in your teacher dashboard to see the exact order of lessons students will complete. You’ll notice they are not in exactly the same order as they appear in the groupings on your dashboard.
