Digital Photgraphy and Math

  1. 1. Digital Photography "When students take the pictures and actively use them for purposeful knowledge, you have a dynamic combination for engagement and active learning." (McAnear, 2004, p.4)
  2. 2. 2 Great Reasons <ul><li>The possibilities are only limited by your creativity. </li></ul><ul><li>Students find it incredibly motivating. </li></ul>
  3. 3. Framework <ul><li>In the May, 2004 issue of Learning and Leading with Technology , Glen Bull and Ann Thompson provide readers with a four-step framework for the use of digital images across all content areas. </li></ul>
  4. 4. Step 1: Acquire <ul><li>Where does one find digital images to use in the classroom? </li></ul><ul><li>The NCTM theme standard Connections states that students should be able to connect mathematical concepts to the outside world. </li></ul><ul><li>Digital cameras can get students out of the classroom and into their environment to capture real-world examples of mathematical concepts. </li></ul>
  5. 5. Acquire--Example <ul><li>Most common example is having students find geometric concepts around the school grounds </li></ul><ul><li>Students can easily find examples of parallel lines (sidewalk cracks, power lines), right angles (bricks on a wall), shapes, geometric solids, and on and on. </li></ul>
  6. 6. Step 2 Analyze <ul><li>Use of images can involve many kinds of analysis on the part of the student. Our goal is to get them to see mathematical concepts in real-world images. </li></ul><ul><li>One of the best ways is to use a photo as the basis for a writing prompt and have students solve the problem. </li></ul>
  7. 7. Analyze--Example <ul><li>What would the word HOT look like after being rotated 180°? </li></ul><ul><li>What would it look like after being rotated 270°? </li></ul><ul><li>What would it look like after being reflected across a vertical line just to its right? </li></ul><ul><li>What would it look like after being reflected across a horizontal line below it? </li></ul>
  8. 8. Step 3: Create <ul><li>Educational activities often involve products. Many technologies make it easy to incorporate digital images. </li></ul><ul><li>Students can make slide shows, blogs, posters, class books, art projects, etc. </li></ul>
  9. 9. Step 4 <ul><li>Products are not always meant to be read only by a teacher, but also to be communicated to a larger audience. </li></ul>
  10. 10. Example 1: Multiplication <ul><li>If there are nine small squares in one tile, how many squares will there be in 5 tiles? </li></ul>
  11. 11. Example 2: Subtraction <ul><li>How many MORE black and white fish are there than orange fish? </li></ul>
  12. 12. Example 3: Measurement <ul><li>Measure and photograph each student during the first and last week of school. </li></ul><ul><li>Compare data. </li></ul>
  13. 13. Example 4: Fractions <ul><li>What fraction of the candy canes are NOT red? </li></ul>
  14. 14. Discussion <ul><li>Gather with the other people in the class who teach at your same grade-level. </li></ul><ul><li>Brainstorm ideas for using digital photos in each of NCTM’s content standards. </li></ul><ul><li>Make sure and tie each activity to your core curriculum. </li></ul>
  15. 15. Think About It… <ul><li>What math questions could you bring out about this photo? </li></ul>
  16. 16. Other Ideas for Using Photos <ul><li>Illustrate steps in a process </li></ul><ul><li>Photograph favorite foods and then graph </li></ul><ul><li>Permutations </li></ul><ul><li>Identify patterns in nature </li></ul><ul><li>Illustrated dictionaries of math terms </li></ul>
  17. 17. NCTM Content Standards <ul><li>Number & Operations </li></ul><ul><li>Algebra (think patterns & functions) </li></ul><ul><li>Geometry </li></ul><ul><li>Measurement </li></ul><ul><li>Data Analysis & Probability </li></ul>
  18. 18. Your Assignment <ul><li>Take a digital photo that can be tied to your math core. </li></ul><ul><li>Remember the steps: </li></ul><ul><li>Acquire the photo. </li></ul><ul><li>Analyze the photo for its math connections. </li></ul><ul><li>Create the product. </li></ul><ul><li>Communicate (by turning it in to me!) </li></ul>
  19. 19. Example Assignment:
  20. 20. Wait!!! I don’t have a digital camera!!!
  21. 21. Never fear, there’s an alternative.
  22. 22. Alternative Assignment <ul><li>Create another technology lesson plan using the form you did this morning. </li></ul><ul><li> </li></ul>
