I have observed that many students in my most advanced courses still struggle with numbers above one hundred. Here is a video I made to go over things step-by-step.
This first video covers 100s through 900s, and the next one will be practice (with memes!) with the thousands up to the millions!
Here´s a PDF activity sheet for a comprehension check after the video! Los números 100 – 999 PDF Activity Sheet
Here´s the answer key! Los números 100 – 999 Answer Key
Enjoy the video! Any feedback welcome in the comments!
