The BIG 20 was developed by George Rule of Orlando in the early 1970's. It consists of 20 problems types you will encounter on a daily basis, either directly as they are shown, or as parts of other situations. Furthermore, the better you are with the skills of the BIG 20, the better your chances for success in mathematics.

I have seen secondary students (with a very poor history of success in mathematics) do the BIG 20 in less that 2 minutes and get them all correct.

Give this a try. Try to complete this in under 2 minutes (no calculator allowed).

Note: 3^{2} means 3 squared and ^{1}/_{4} means
one-fourth.**
