Pre-Calculus by Design
This book is one of a series that use a "search n shade" technique to create a fun way to learn and reinforce mathematical concepts.
Students use a shading code to shade a grid on which answers to exercises are found. If the exercise answers are correct, a symmetrical design develops.
"Pre-Calculus by Design" contains 42 activity pages covering a range of trigonometry and other pre-calculus topics. These include trigonometric functions and laws, graphs of functions, working with logarithms and exponentials, arithmetic and geometric series, and limits.
