Here's how the lingt classroom site works.
If you click on the link to the right, it will take you to a page where you can select which class you're in (am/pm). Then look at the newest assignments/vocabulary. You can have your child practice telling you the sentences and words, then listen the recordings by clicking the blue speech bubbles. Your child can record their voice (so I can hear it too) by clicking on the gray bubble to the right.
Below is an example of what an assignment looks like
Not many people have been using the site so I am not sure if you don't know about it or if it isn't very useful. Please try it out and let me know what you think and if I should keep doing it. Thanks!
