Earning a Badge is one of the ways that you can move up on the leaderboard, where you can compete against other learners in the same track. Badges are a fun reward that you can earn when you complete all lessons related to one topic.
For example, see the Measure Me! badge below? Do you see the lessons that are a part of that badge? What do you notice?
That's right--all the lessons in that badge are related to measuring! There is the lesson Comparing Objects by Length, Ordinal Numbers, and more! Badges consist of lessons, series, or a combination of both!
To earn a badge, complete all the lessons that make up that badge.
To see all the available badges, click on the "Badges" tab at the op of the page. To see the badges you have already completed, click on the "Achievements" tab at the top of the page, and then scroll down to where it says, "Completed Badges".
There are lots of badges and rewards to be won, so get in there and start earning today!
