Newman's prompts Newman's prompts Finding out why students make mistakes The Australian educator Anne Newman (1977) suggested five significant prompts to help determine where errors may occur in students attempts to solve written problems. She asked students the following questions as they attempted problems. 1. Please read the question to me. 2. 3. 4. 5. These five questions can be used to determine why students make mistakes with written mathematics questions. A student wishing to solve a written mathematics problem typically has to work through five basic steps: The five questions the teacher asks clearly link to the five processes involved in solving a written mathematics problem. If when reworking a question using the Newman analysis the student is able to correctly answer the question, the original error is classified as a careless error. Research using Newman's error analysis has shown that over 50% of errors occur before students get to use their process skills. Read more about Newman’s error analysis

Grid Paper PDFs Free Online Graph Paper / Grid Paper PDFs Downloadable and very printable, I find these PDFs extremely useful. Tip number one! Though I do return the correct header for a PDF, sometimes Explorer gets confused when downloading... Tip number two! Some people may need to turn off the option in Adobe's Acrobat reader "shrink to fit" which may resize the grid slightly to fit your printer's printable area. Tip number three! If you want the hexes aligned with the other edge of the paper, just make your paper size "11 x 8.5" and print the result in landscape mode!
