You can now go back to the first picture and see if there are any more possible rectangles that can be arranged with the yellow pieces.īy the way, this get trickier if the pieces are negative. Then, fill in the missing chunks with the skinny (red, means negative) rectangles, representing x. Then, fill in the missing chunks with the skinny (green, means positive) rectangles, representing x. Then, I arrange the yellow tiles into a rectangle.Īll (big blue square and rectangle of yellow small unit squares) of the pieces will make a rectangle, with missing chunks, the missing chunks represent the missing b term in the quadratic. When you use tiles to factor, you are trying to arrrange the tiles into a rectangle (think area model). I found it to be easier if I used Algebra Tiles, especially with the last problem, which, by the way, has more than a couple answers.īy the way, I usually teach factoring with Algebra Tiles. Your TV screen displays vertical or horizontal lines in red, blue, green, white or black. Use Algebra tiles to see this physically. Its visible if you open the settings menu.
