Less than $5 12th Grade Precalculus Resources (by date, latest first)

This is a fun and engaging game that can be used as a review or an informal assessment of operations on rational expressions. The operations included are adding, subtracting, multiplying, and dividing.

Minimal preparation for game is needed. Just copy the board games on card stock or laminate if you plan to reuse. Will need some sort of game pieces, but these could be colored paper shapes. I suggest dice, but could use with spinners just as easily.

Answer key and blank board game is included for students to write their answers.

Practice using function notation with numerical values and algebraic expressions

Worked solutions are included

A mixture of problem solving questions on Arithmetic and Geometric Series.

A useful task to assess understanding of both types of series. Could also be used as a homework task or a class assessment.

Worked solutions are included.
