This geometry bookmark is perfect to remind your geometry students of all of the important formulas. Each page prints 3 double-sided bookmarks loaded with formulas, tips and theorems. This file comes with a .pdf as well as an editable Word document so that you can adjust this to suit your needs. This bookmark was made for my students using the SpringBoard Geometry text, but the formulas are applicable to any traditional geometry text.
Directions: Print out the two pages containing the bookmark double-sided, flipping along the short edge. Print on cardstock so that it will last the entire year. Cut along the dividing lines, and distribute one bookmark to each student. Students can use this as a bookmark in their textbook, workbook, notebook, etc.
