## Full alternative

Complete neutral fictional source: Two separate fictional records use cards. Record 1:□−175=428, where 175 cards are used and 428 remain. Record 2: 620−185=□+240. Keep the records separate. There is no supplied history of a learner’s earlier work.
Four exact own prompts, in order: 1. For Record 1, say what the box counts and find it. 2. Substitute your Record 1 value into its original equation and check. 3. For Record 2, find the box value. Show what the complete known side is first. 4. Check both full sides of Record 2 after substitution.
Each response area is genuinely empty; no sample answer, equation, strategy, faint model or watermark appears inside it. Staff criteria and next lessons are separate.
