One value, two representations
Each sheet has eight questions in each direction. The selected decimal interval applies to the value, whichever base is printed in the question. Both endpoints are included so that the smallest and largest representations receive practice.
The preview and downloaded PDF use the same questions. Include answers to append a separate key, or download just the student worksheet.
