6.1 Learning about Multiplication Using Dynamic Sketches of an Area Model - 29 views

  • The figure below shows a rectangle with width 3 and height y. The product 3y represents the area of the 3-by-y rectangle. Change the value of y by dragging the red point up and down the vertical axis. Note that as the point is dragged, the area of the rectangle changes simultaneously.

      This is a great exploration for students to begin making connections between whole number multiplication and decimal multiplication.  One modification I would make is to have students make a partition (on grid paper) to show the partial products so I could connect the figure to a symbolic algorithm for multiplication and the distributive property.  For example, if it was 1.2 x 3, the partial products might be (1x3) + (.2 x 3).

    Not getting into your site. Is it down?
  •  
    I hoped if I just waited a day the site would be back up. I really am interested in good math interactives. I am hopeful the site will be restored or redirected.
  •  
    I agree. The day I used it, it was fine but the day after it was down. It seems the whole 'learnalberta' site is down.
  •  
    Ok. I offer this site instead: http://interactivemaths.net/
