How many problems does he normally need to do? I have never seen an actual fourth or fifth grade math curriculum, but sometimes DD's little friend on our street who is in fourth grade brings over his math so DD can help him with it. The little I have seen is generally a worksheet with a front and back side. DS went straight from 2nd grade math to 5th/6th grade math and DD went from 3rd to 6th so I don't know what is "normal" for that grade. But even the 6th grade homework is just one sheet front and back (the Envision curriculum).
So the answer is, an hour is probably too much but does it take everyone that long, or is the child unfocused?
