Aaron Daffern on YouTube
Aaron Daffern’s YouTube channel breaks down standards for you to better understand the “why” behind them. There are hundreds of short videos that explain many concepts that will help you teach children the conceptual reasoning behind mathematical ideas. His videos are specifically aligned to Texas State Standards, but there is a great deal of commonality. This is definitely a channel to check out that could be a nice complement to Keep Indiana Learning’s latest Big Ideas documents!
