Saxon math fact cards might be what you are looking for ??
I'm in the same boat. I bought a used saxon math set and it didn't have the fact cards with it. I was debating making my own, but it was too tedious. The fact cards sold in most stores don't seem to have all the families

I'm not sure what you mean by fact families. Saxon uses that term to teach how one can use three different numbers and create four different addition and subtraction facts. Thus 3,5,8 can be a family, because it can create 3+5=8, 5+3=8, 8-3=5 and 8-5=3. But then there are the fact solving strategies that Saxon teaches. In addition the strategies are doubles, add 0, add 1, add 2, doubles plus 1, add 9, sums of ten and odd balls.

Thats exactly what I mean by fact families ochumgache. I was wondering if there were a "master list" available somewhere. Like, with every possible combination of fact families for numbers up to a certain point, say...15. I dont know for sure.
I made family trees for my son. I printed out a tree template, and then printed out a cherry template (2 cherries joined at the stems). I have (for example) a big number 7 on the tree trunk, and then on the cherry sets of 2, I have 4 & 3, 7 & 0, 6 & 1, and 5 & 2. That way he knows that no matter how he sees the numbers together ... 5-2-7 or 7-3-4 or whatever, they're a family. The smaller two numbers are the same as the big one, so adding or subtracting, the game is the same... "who's missing from the family?"
Not sure if that helps you or not. I didn't use any cards or anything. I just made it up myself. That might be more work than you have time for, but it's cute to have little trees hanging around the room.
R&S teaches a similar concept. Rather than writing out every time ... 8+2=10, 2+8=10, 10-2=8, 10-8=2, they just teach "triplets", so 10, 8, and 2 are triplets. They go together no matter whether you're adding or subtracting. Just see which one is missing.

R&S also has "Bees and Blossoms" posters you cut apart. Each blossom (looks like a huge clover head) has a number on it, and each bee has two numbers with one on each wing. So you can match up, for example: Blossom 12 with bee 2/10, 3/9, 4/8, 5/7, 6/6. Then you can just cover up one number and have the student tell which number is missing.
Somebody makes triangle shaped flash cards, with triplets, one number in each corner. You show the card with one number covered and the student says what number is missing, adding or subtracting to find out the answer.
