iPad with ScratchJr app installed would be best. 
Chromebook/Laptop is the next best but will require mouse skills if not a touchscreen.

Android tablers have caused the most frustration with students as the touch calibration is off. This can be especially frustrating when drawing. Feel free to test your device in advance. When drawing, the "ink" should appear exactly where your finger/stylus/mouse pointer makes contact with the screen. It should not be offset by any distance.

It is encouraged to have two devices. One device for watching the recording and a second device for coding. With a single device, a student will be switching from the video to the ScratchJr app and back and forth. For younger learners, this may cause some frustrations.
