Ask educators to create a single three-step word problem for PreK–Grade 2 that uses addition and subtraction within 20, incorporates equal sharing among groups (partitioning or fair-share), and can be solved concretely by students using drawings (e.g., drawings of groups, dots, bars, or tally marks). Specify the problem stem, full numeric answer, and a model solution showing the three steps with drawings and brief teacher notes on expected strategies and common misconceptions.
