UDL Action & Expression (Formative)

1. How can Principle 2: Action & Expression: Formative Assessment be effectively integrated into your teaching? You can allow students to show you what they already know about a certain subject. If you do those pre assessments, then you do not need to re teach a subject that the students already know, you can spend that time doing something fun and teaching something the students do not know as much about. I like the action formative assessments that we got to play around with in class today. I feel like letting the students use some of these tools can help them gain and even deeper understanding of a subject. I would love to let my fast finishers do a lot of these tools to express what they have learned. Sometimes I feel like its harder to let the slower learners do some of these tools so maybe having them buddy up with someone who is a little faster can help with that. 
2. How will this help your students? Like I said before I feel like it helps them gain a deeper understanding of a subject. But I also think that it helps a lesson be memorable to those students. They get to be proud of something they have created. And in doing so with the buddy system, helps them learn how to work with others, and maybe helps them teach another person, or learn from another person something about the subject that maybe they had not thought of before. 
3. What are your goals with regard to this topic? My goal is to let the students do a fun action formative assessment as often as we can. I know sometimes it is hard because you have so many things you need to teach and test students on but allowing them to do these fun assessments can help with those students who have test anxiety like I had as a student but still shows what the student knows, just in a different form so they are more comfortable with it.  

Here is a ThingLink I created as I could test my students on and have them fill in what the bubbles would say once you clicked on them, to test their knowledge of the Water Cycle.
