Step 1: Grab a copy of “Book of Quadrilaterals Page” and “Vocabulary” pages.                              Step 2: Copy them with one of them flipped 1- 2 sided (I copy on white paper so my students can highlight)                              Step 3: Grab the “Quadrilateral Family Tree” and “Trapezoids” pages.                        

INSTRUCTIONS FOR FLIPBOOK: Note: It matters the pages you copy 2 sided together or it will NOT work out.

 Step 4: Copy them with one of them flipped 1- 2 sided                                  Step 5: Grab the “Parallelograms” and “Squares” pages.                          Step 6: Copy them with one of them flipped 1- 2 sided                            

 Step 7: Grab “Rectangles” and “Rhombi” pages.                            Step 8: Copy them with one of them flipped 1- 2 sided                              Step 9: Stagger them like this (I have my students do it in a warm-up) in order (From Bottom: Vocabulary ! Trapezoids ! Squares ! Rhombi) ORDER MATTERS!          

Step 10: Grab the papers like pic below and fold it over                                        Step 11: Your finished product will look like pic below and staple it at top (try to staple VERY CLOSE to top so you have as much writing room as possible – I emphasize this with my kids in the directions).
