Using Blocks to Teach Math

It was nice to admit outloud to another homeschooling mom the other day that I completely failed at teaching math.  See, we have officially reached CJ's actual learning level of math and I'm so used to him picking it up super easy that I was lazy and didn't teach him the concrete subtraction that borrows from each greater place value.  I taught him the shortcut.  On paper.  Bad homeschool mom.  I know better, and since I was able to admit my fault to a dear friend I was ready to go back and commit to making it right.  So today, we did subtraction with blocks.  LOTS of blocks.  And got through 3 problems in a full hour.  ONLY THREE!  I had to keep telling myself (in my head) to chill out.  Because seriously it was SO slow.  So there you go, a little error on my part.  It happens to the best of us.
