Whiteboard Addition & Subtraction Videos

I’m putting together a short series of whiteboard-style video tutorials that teach addition and subtraction to elementary students aged 9-11. The goal is to break each concept into clear, engaging steps, use simple line drawings that animate onto the screen as I speak, and insert quick “pause and solve” moments so learners stay involved. Here’s what I need from you: • 3–5 concise whiteboard/explain-type videos (around 3-5 minutes each) that cover basic facts, regrouping, and multi-digit problems. • Scripting and storyboarding that keep the language age-appropriate while still challenging the learners. • Clean voice-over (native-level English), synchronized to the drawings and handwriting-style text. • Production in 1080p MP4, ready to upload to my LMS, plus separate caption files for accessibility. I’m happy if you prefer tools such as VideoScribe, Doodly, or After Effects, as long as the final look is the classic hand-drawn explain-video style. Please include a quick outline or sample frame when you respond so I can be sure our teaching approach aligns.
