Export: At the end of my lesson I can export to a PDF and post to my website or I can print out what I taught.Highlighter: Frequently I like to highlight.If the students did not do well on a question, we keep doing questions until they are getting it. Allows me to let data control my lesson (when I use my Expressions). But when I have something pre prepared I can insert a blank page to do another example when the students need additional practice beyond what I pre prepared. I’m busy and my promethean board is a tool, it shouldn’t suck up all my outside of classtime. Create a blank page: Rarely do I pre make a flipchart.This makes it a lot easier for students throughout the year to attach the negative to the number to the right of it. Subtract 3, negative 3, subtract 3, negative 3. My favorite example is 10 – 3 and trying to get the students to get that the 3 is negative really comes home when I turn on the spot light and the 10 is not visible. Spotlight tool: When a student is not understanding a concept being able to block out all the “noise” on the board and just look at one part of the problem brings a lot of clarity.With reducing monomials being able to look at the coefficients separately from the variables and exponents really helps students to compare and contrast. I pass out post it notes to the students so they can duplicate the effect on their paper. Being able to black out the screen and pull it from left, right, top or bottom to reveal only the part of the problem I want to focus on is a huge help. Black Curtain: Frequently I want to focus on one half of the equation or part of the problem.I love not having to copy what I just wrote. I write the expression with parenthesis, lasso, duplicate and then fill it in. Especially when I do substitution, I want to show the parenthesis and THEN fill them in. Duplicate annotation: As I am writing I want the students to see the progression of the math problem.This is awesome for when you inevitably get the question from a student “I don’t understand what you did.” Well I can back up and walk through it very carefully again. If I press the arrows to go backwards I can show what I did step by step by step. Duplicate the page: After each step I will duplicate the page which gives me several advantages.Those chart paper sheets are expensive… how do I hang them up? With my promethean board I have graph paper with a single click… and as much of it as I want.
