Hi Karly,
I'm new to homeschooling, working with my 6 year old 1st grader. I'm in the same boat as you. We started with Saxon and after 3 days of it I realized it was not for us. Since then we've been doing 2 worksheet pages per day from math mammoth and supplementing with literature, online math games, cooking projects, etc. We're having much more fun now, but I'm not sure how much I like Math Mammoth. I just ordered the first book of Singapore on the recommendation of a math teacher friend, and it should arrive today. I'm thinking I will use that and/or mammoth.
But the other activities have really been the best. Today we're reading a book called "The Doorbell Rang" by Pat Hutchins and having a cookie party with her stuffed animals where she'll divide cookies among them.
Best of luck,
Rich
