Learn the idea
Data is recorded information. A picture card can stand for one choice. If each child chooses one activity, one card for that child keeps the record fair. Two cards from the same child would count that child twice. We use pretend choices here; nobody needs to give their own information.
Match one card to one stated choice and check that no choice is counted twice. More cards do not always mean more people when a choice has been duplicated.
Use this supplied case: A pretend learner chooses blocks and one blocks card is saved. Classify the record. Use the details in this example. An adult may read the words aloud. Point, draw or say your answer.
- Follow the worked example one step at a time. Say or draw what happens.
- Match one card to one stated choice and check that no choice is counted twice.
- Say which detail makes the example answer fit. Pick another answer and say why it does not fit.
- Try the question and practice questions. Read the rule again if your answer does not match the explanation.

Three pretend learners choose blocks once each; a recorder saves four blocks cards. Expected: at least one card does not represent a distinct single choice under the rule. Do not guess which learner.
