You both would probably like the math I had to do in 6th grade. It was called Arithmetwists. Mainly what is was is there were four or more numbers in a row with little squares for the signs, then an equal sign, and then the answer. You had to get it to equal the answer with plus, minus, multiplication, and division signs and parentheses. It started easy and then got 'harder'. There was also another part where it was opposite, you had the signs in the order and a list of the numbers you could use. You had to fill them all in. I thought it was a lot of fun, but there were some people who hated it and thought that math should be done with rows and rows of problems.
