Just finished 2d grade here as well:
Reading: worked on fluency and comprehension. We used Sonlight Regular Readers 2 & some ETC
Grammar: parts of speech (verb, adverb, adjective, prepositions), sentence and paragraph structure, review capitalization, titles and memorization. We used FLL 2 and some SL LA
Science: some life science, magnetism, earth science, simple experiments, lots of gardening, zoo trips and library trips. After hopping around settled with Seton Science as a back bone for our studies.
Math: Math U See Alpha & Beta. We started at the beginning with math facts for addition and subtraction, place value, money, skip counting, mental math, telling time, measurement. We also worked on "fast adding" as an intro to multiplication.
History/Geography/Literature: Sonlight Core 1 - Ancients... we liked to try and duplicate what was listed. So if there was a recipe in Peoples of the world we made it, fastened togas, built an egyptian water clock, etc.
Music & Art didn't get finished to the degree I would have hoped.. next year I intend to out source
Also next year we are going with a full curriculum to make sure we cover everything to the degree we feel comfortable. Seton Science was so impressive we've opted to go with them.
