What will be an ideal response?
Complete answers will include the following information. Children should show concrete proof of equivalency by using base-ten blocks and comparing decimals.

They should be able to rename one decimal fraction to an equivalent form. They will have a mental referent for the process. The generalization that adding zeros to decimal fractions produces number of equivalent value is not difficult to conceptualize.
