I signed up for a fun site called Homeschool Freebies Each day they have an E-Book that you can download for your personal use-for free! I thought today's freebie was super cool. It is called Everyday Number Stories, geared for 2-5th grades. It is a math book from 1915 and I really enjoy the way it is layed out. I think even Mustang (who is 4) will be able to do the first few pages. Check it out, it is only for one day.
