I was planning to just make my own curriculum, but now I am getting scared to do it that way. So I've been looking for used curriculum, but I'm afraid to buy anything, since our budget is almost non existent, and have it not work well. So I thought I'd get some advice here....
I have two kids. My first one is almost 11, entering 6th grade, but ready for prealgebra, at least. He catches on quickly and loves math. I'm afraid he has some small gaps since this is our first year homeschooling-but he will be able to fill the gaps quickly with just a quick lesson from me. He will thrive on almost any math curriculum I think.
My younger one is 10. She is still working on those basic multiplication/division facts, and even some addition is not as quick as it "should" be. She is still using her fingers for things like 7+5, but mostly when it's up higher like 27+5. I would like to solidify those skills, but also want to push her along because she is capable, she just wasn't thriving in public school. They used a spiral curriculum and I think that was part of the problem, I think she really needs a mastery program rather than spiral.
If I choose to buy something for my oldest, ideally I would be able to hang on to it and use it in a couple years with my youngest. We were going to use Khan Academy, but now I am just afraid that is more of a supplement than to actually use it as a primary curriculum or guide for math.
Any ideas or suggestions? I am open to any tips, I have found a lot of used resources online, so if there is a curriculum I really want, I am willing to search for it and wait a bit to get it. I'm just not sure what I want to be looking for.
