How to write and use better fraction quiz questions
Choose questions by prerequisite skill
Start with fraction meanings, then select equivalent fractions and comparisons before moving to operations. Students can cover each answer while they work and uncover it to check their reasoning.
Make the task and units clear
State whether a response should be simplified and include units in measurement problems. For a number-line question, describe the endpoints and divisions so students do not need a missing diagram.
Check answers and equivalent forms
Work through each calculation independently before using it. Unless a question asks for simplest form, accept equivalent fractions, such as 6/9 and 2/3, when they represent the requested value.
Use mistakes to guide practice
Ask students to explain an incorrect answer, as in the denominator error in question 23. Their reasoning can show whether they need more practice with equal parts or a particular operation.
