Informal Geometry - Course Information
Successful students will develop sufficient computational, procedural and problem solving skills to provide a solid foundation for further study in mathematics. The text provides ample practice for students. Challenge exercises are includes throughout the pupil text. Activities and Geo-Activities provide students with models for conceptual understanding of the mathematical reasoning behind every key concept. Mathematical reasoning is stressed throughout each chapter. Vocabulary words, examples and guided practice exercises are standard features of each chapter. Each lesson includes mixed review exercises so that students can recall and use skills and understandings from previous chapters.

Successful students will need a notebook/folder, book, paper, pencil, and calculator (Texas Instrument TI-30XIIS preferably) each day. Homework will be assigned most every night. Nightly homework, which the students have time to start in class, can be completed at home in less than one hour. Homework is due the next school day.

The studentís grade is comprised of a weighted combination of homework, class participation and test scores. It is the student's responsibility to make-up missed assignments due to an absence. The student will be allowed at least the same number of days for make-up as the number of days absent. I am available for extra help after school provided there are no schedule conflicts.
