Equivalence of fractions

Which is bigger, a half or two quarters?

This can also be done by re-folding and discussing eighths.
Which is bigger 3/4 or 5/8 ?
Which is smaller, 1/2 or 3/8 ?
Which is bigger, 2/4 or 4/8 ?
Similar work can be done with thirds and sixths. Folding becomes difficult for fifths and tenths so it is best to develop the concept with fraction families that are easy to fold. However, similar work can be done on squared paper.
Addition and subtraction within fraction families where equivalences exist.
Add 3/4 and 1/8 ; add 1/3 and 1/6
