PLE Number Challenge
Use number facts, operations and estimation to choose an answer—and defend why it makes sense.
THE CHALLENGE
The Number Evidence File
Your PLE study team has fifteen number claims to investigate. For every claim, identify the rule, calculate carefully and use estimation or number sense to check the result.
What does each digit mean?
Notice the place value, unit, fraction, base or operation before calculating.
Decide before you calculate.
Write the operation or property you need. This prevents random working.
Estimate and explain.
Ask whether the size and form of the answer fit the original question.
