Too many students make it to high school math without really understanding certain arithmetic and algebra procedures. One such procedure is "cross multiplication."
Today I made six pages that can be printed out and quickly turned into a wall poster explaining how to cross multiply and showing why it works. The pages are plain and have lots of white space to draw and write in tips where a teacher/parent/tutor wants to customize the poster.
Here are the files for free to use for educational purposes:
 |
| Page 1 - upper left |
 |
| Page 2 - upper right |
 |
| Page 3 - middle left |
 |
| Page 4 middle right |
 |
| Page 5 - lower left |
 |
| Page 6 - lower right |
Print out all six pages, then cut/glue/tape them together onto a posterboard. Decorate and draw connecting arrows as desired.
