well, do a mix of everything down there
i like to set rewards for myself, like...
*WARNING STUPID METHOD*
for math/reading. if in math i complete 5 problems i will them eat a gummy bear. and then 5 more. then another gummy bear :D
or for language arts/reading, read a paragraph, do something else for 5 minutes, read another paragraph, then something else, or yet again eat sweets to compel myself
