I use this reference page in three ways:
1) Glued to students homework page
2) A laminated copy in their notebooks
3) The half-page sheet as a bookmark in their math book
To make the half-page sheet, I copy the pages back-to-back on card stock, laminate, and cut in half.
This reference page includes:
-Key Words for Solving Word-Problems
(addition, subtraction, multiplication, division)
-12 X 12 Multiplication Table
-Order of Operations (PEMDAS) Directions
-Prime Numbers to 107
-Place Value Chart
-Number line from Negative 2 to Positive 6
-Common fraction-decimal Equivalents
This page seems to help my students a lot with learning new math concepts.
