Attention Grabbers
Make your own animated comic strip! So much fun and definitely an attention grabber! In fact, I think this would make a fun assignment for the students; don't just limit this one to attention-grabbing. I've personally just have never been creative enough to know where to start... Luckily PowToon has easy templates to help you get started.
This is a really great slideshow creator- for many, it is their creator of choice. And now, they have a Photo Peach exclusively for educators, with assessment tools and exclusive privacy settings.
I find Smilebox easiest to work with, but it is paid, and they give you a free trial, so I've always used that. It is really easy to make professional-looking slideshows. I've just always been annoyed with all the downloads and the prompts to pay for a full subscription. But if you are into making a lot of slideshows, their templates are great and it may be worth the full service for you. Check out by Smilebox attention grabber below!
