How KangarooKiddo teaches it
Sessions are short and end on purpose. Your child gets a 30 to 90 second lesson, then a handful of questions matched to where they are, with a gentle hint and a retry on a miss. The parent dashboard shows whether add within 100 is mastered, practicing, or needs work, mapped to the real standard.
