Using Google Slides 3rd grade students will create a 13 slide presentation, one month at a time, over the entire school year.
It is never too early to start building a digital portfolio and not every portfolio will look the same. But one great way to show true growth and progress is not to publish the best of the best, as most portfolios tend to be, but rather show real, individual progress and growth though the eyes, and words, of the students themselves. It's important for students to think about, and voice, the things that stand out to them the most, their "a-ha" moments of clarity, their personal triumphs. It is also important for students to keep a record of such things and look back on them. It's one thing for us as teachers to say "you've come so far" but it's far more powerful for the student to look at a body of work and say "this is how I've grown."
