These videos are not short clips that introduce a specific instructional activity — they are dense, and require time and thought to understand and implement. The materials form instructional sequences for first-grade mathematics, with aspects suitable for kindergarten and second grade as well. Materials include templates, detailed notes, and videos organized into groups covering efficiency with the rack, and grouping strategies for addition and subtraction.
We recommend watching the videos in order.
