Rounding Using a Number Line
I originally used a video and added it to EdPuzzle and added some questions. I reread the directions for the assignment and thought it didn't fit the description. The good news is that I have that other thing done for next school year. :-) Come to find out, it took longer to find an appropriate video than it did to create one. I had to hurry and create the video because I got strep throat from a family member and figured I would not be able to talk much soon. Thankfully I did, because today I sound cool like Batman...but not a good recording voice.
Anyway, this video will be used in a math lesson on rounding. I can possibly use it to introduce, but it is likely better used for the lesson content (or for those absent- or as review). I am trying to show a strategy for using the students' understanding of tens (and later hundreds and thousands) to help get a visual understanding of rounding.
I think this type of video works because it is dealing with steps with rounding. It also shows students a way they can set up the same step for understanding the process. Being able to use the app, Educreations, helped with the recording of the screen. I could have used a screen capture on the computer, but it looks like a 3 year old drew the numbers and lines. I have used Educreations in the past, but only as a white board app. I had never used it to record a lesson. It was pretty simple. It took a couple extra steps to mail it to myself and add it to YouTube, but mostly simple.
When I was first trying it, my iPad did not want to respond to touch-it hasn't been updated in a while. I was getting a little frustrated. I tried recording this several times and messed up and had to start over. There did not seem to be the ability to rewind. or trim the video. It was all or nothing. I tried doing this probably about 10 times. Each time, I messed up something-talking too fast, mumbling, a lot of 'uhs', my drawings were crazy(er), the buttons wouldn't work. I would probably work on having an easy to read script. Though, if I am honest, if it takes too long to create a lesson, I will not likely use it much in class. Maybe look at adding one new lesson each week.
For my students, I know Seesaw has the capability to record your screen while explaining. (I'm not sure about the trimming).
I think this shows the cognitivist philosophy because of the need to build on prior knowledge of place value understanding. I think this will help students because the video is short and if needed, they can rewatch. With how easy it was to this kind of activity, I might include an activity that has the students create their own lesson. Or a worksheet with 100 practice problems. It could go either way. :-)
