Sixth graders are given tables showing x and y values that have a linear relationship.  Here's how they're supposed to fill in these tables.

Synthetic Division is a way to divide one polynomial by another one, as long as the divisor is a binomial with an x-coefficient of one.  This page has an example of polynomial division, which you should be able to follow well enough to understand that, too.

Square Roots can be found using a procedure similar to long division.

Finding a Common denominator.

Sometimes you have a "black box" that is a polynomial, but you don't know the order of the polynomial or its coefficients.  But you can feed numbers into the black box, and get results out of the black box.  This procedure tells you how to find the coefficients, using an example: the sums of powers of 6.
