Flashcard 1: Identify the best criterion to check a solution that gives the right final answer but no work shown.
Answer: Completeness. Missing work shows incomplete reasoning.
Flashcard 2: What does it mean to compare two pattern-based solutions using clear criteria?
Answer: Judge which solution fits the pattern best using the same rules for both. Apply the same standards to evaluate both solutions objectively.
Flashcard 3: What is a criterion when you compare two solutions to a pattern problem?
Answer: A rule or standard used to judge each solution fairly. Criteria ensure objective comparison without bias.
Flashcard 4: Which criterion checks whether a solution matches every step of the pattern?
Answer: Accuracy (matches the pattern rule each time). Accuracy ensures the rule is followed correctly throughout.
Flashcard 5: Which criterion tells whether a solution includes enough information to follow the reasoning?
Answer: Completeness (all steps or evidence are included). Complete solutions show all work for verification.
Flashcard 6: Which criterion focuses on whether a solution is easy to understand and well organized?
Answer: Clarity (steps are labeled and easy to follow). Clear solutions help others understand the logic.
Flashcard 7: Which criterion checks whether the same pattern rule works for more than one example?
Answer: Consistency (rule fits multiple terms or cases). Consistent rules work for all given examples.
Flashcard 8: What is the first action you should take before judging which solution is better?
Answer: State the pattern rule being used. Knowing the rule enables fair comparison.
Flashcard 9: Which option is the best criterion for deciding between two correct solutions: fewer steps or clearer steps?
Answer: Clearer steps. Understanding is more important than brevity.
Flashcard 10: Identify the best criterion to check a solution that changes the rule halfway through the pattern.
Answer: Consistency. Rules must remain constant throughout patterns.
Flashcard 11: Which option is the correct next term if the pattern rule is “add 3 each time” and the last term is 14?
Answer: 17. 14+3=17 follows the addition rule.
Flashcard 12: Which option is the correct next term if the pattern rule is “multiply by 2 each time” and the last term is 9?
Answer: 18. 9imes2=18 follows the multiplication rule.
Flashcard 13: Which solution matches the pattern 2, 4, 6, 8, __: A says 10; B says 12?
Answer: Solution A. Pattern increases by 2 each time: 8+2=10.
Flashcard 14: Which solution matches the pattern 5, 10, 20, 40, __: A says 45; B says 80?
Answer: Solution B. Pattern doubles each time: 40imes2=80.
Flashcard 15: Identify which rule fits the pattern 3,7,11,15: A add 4; B multiply by 2.
Answer: Rule A (add 4). Each term increases by 4: 3+4=7, 7+4=11, etc.
Flashcard 16: Identify which rule fits the pattern 1,2,4,8: A add 2; B multiply by 2.
Answer: Rule B (multiply by 2). Each term doubles: 1imes2=2, 2imes2=4, etc.
Flashcard 17: Which solution is more accurate for the pattern “add 5”: A 6,11,16; B 6,12,17?
Answer: Solution A. A correctly adds 5 each time; B adds 6 then 5.
Flashcard 18: Which solution is clearer: A lists only the final term; B writes the rule and labels each step?
Answer: Solution B. Showing work and rules helps readers understand.
Flashcard 19: Which criterion is best for choosing between two solutions that both match the pattern but one is easier to follow?
Answer: Clarity. When accuracy is equal, clarity determines the better solution.
Flashcard 20: What is a fair comparison method when two students use different rules for the same pattern question?
Answer: Test each rule on at least two terms and compare results. Testing multiple terms reveals which rule actually works.
Flashcard 21: Identify the clearer solution: A) “Answer is 20” B) “Rule: add 5 each time; next term is 20.”
Answer: B. Solution B explains the method, not just the result.
Flashcard 22: Which solution is more efficient if both are correct: one uses 2 steps, the other uses 6 steps?
Answer: The 2-step solution. Fewer steps to reach the same correct answer shows efficiency.
Flashcard 23: Which criterion checks whether a solution follows the pattern rule for every step?
Answer: Accuracy (correctly follows the rule each time). Accuracy means the rule produces correct results at every step.
Flashcard 24: Identify the criterion that checks whether a solution uses correct units and labels in a data pattern.
Answer: Proper labeling (units, titles, and clear variable names). Scientific data requires units and clear labels for understanding.
Flashcard 25: What is the meaning of a growing pattern in science data?
Answer: Values increase (or decrease) by a consistent change each step. Growing patterns change by the same amount between consecutive terms.
Flashcard 26: What is the meaning of a repeating pattern in science data?
Answer: A part of the pattern repeats in the same order again and again. Repeating patterns have a core unit that cycles continuously.
Flashcard 27: What is a fair way to compare two pattern solutions when one is longer than the other?
Answer: Use the same criteria; do not reward length by itself. Length alone doesn't determine quality; apply consistent standards.
Flashcard 28: Which criterion checks whether a solution uses the fewest steps without changing the answer?
Answer: Efficiency (fewest reasonable steps). Efficient solutions reach the correct answer with minimal steps.
Flashcard 29: Which criterion checks whether a solution can work for any term number, not only one example?
Answer: Generality (works for all term numbers). General solutions work for any position, not just specific examples.
Flashcard 30: Which option is the best first step when comparing two solutions to the same pattern problem?
Answer: Identify the criteria you will use before judging either solution. Establishing criteria first ensures objective, consistent evaluation.
