Flash cards

Here are some free printable math facts flash cards for elementary level: addition facts and multiplication facts through 12s.  I've been trying to go through some of them most days with my kids. I put them into a "slow pile" and a "fast pile" as we go, to know which ones need more practice.

These PDF files print on letter-size paper that you'll then need to cut apart. 
 I've included each problem forward and backward (for example 6×7 and 7×6) so that kids get used to seeing problems both ways.

If you find them useful, let me know!
