Field notes

The homepage maps 58 listed skills across six grade choices, with topics extending from number bonds and column arithmetic to decimal operations and fraction simplification. Its guidance recommends treating mistakes as prompts to inspect a method, and says Review mode brings recorded errors back for another round. Sound and motion can be adjusted for quieter sessions.
