It's been a busy week here at The Problem Site! In addition to the Halloween Themed Mazes we mentioned last week, we've had some busy teachers creating Halloween Themed Word Lists as well!

If you aren't familiar with our word lists, they are perfect for creating printable word search puzzles, printable jumble worksheets, and printable cross search puzzles. Also, with a Pro Member Account, they can be used to create interactive games in a variety of styles.

So if you're looking for fun Halloween activities for your students and/or children, head on over to the word list pages to get your worksheets! If we don't have what you're looking for, you can always create your own content.

In addition to the word lists, we've had three new Reference Units added to the site this week, all in the field of mathematics.

Determinants: Learn what a determinant is, learn how to evaluate them, and learn how Cramer's Rule can help you solve a system of equations.

Matrices: This unit is a good follow-up to the unit on Determinants; here you can learn what a matrix is, and explore the unique operations that apply to matrices.

Factoring Higher Degree Polynomials: This unit will give students some rules for factoring polynomials of degree higher than 2. The last two sections include some great pointers for grouping terms in ways that will facilitate factorization.
