This started in Grade 8 and 9 where one day of each week was set aside for problem solving. Most importantly, there was an emphasis on learning to think mathematically – they were regularly being given problems that required original thought and were not just knock-off versions of problems they had seen before. The advanced class differed from the regular stream in three ways. The teacher and the students worked together with enthusiasm and a sense of joy. As the years passed a strong degree of group cohesion formed, with the same students and teacher together for so long. Usually, the class had the same teacher for all or most of the five years. ![]() We placed students where they were most comfortable to learn – they were not restricted in any way. Others of equal ability, but with a passion for mathematics, were willing to work very hard to keep their place in the advanced class. Some quite capable students preferred the regular group where they could effortlessly be at the top of the class. In later grades, students still had an opportunity to join the class, but usually had to take a summer school course to bridge the gap. In the early grades, students could move in and out of the class. The advanced class was a five-year program where the students were tentatively chosen at the beginning of Grade 8. ![]() ![]() I taught such a class in advanced mathematics during the last 29 of my 37 years as a high school teacher – and contrary to today’s critics, it was an extraordinarily positive experience for all involved. The Vancouver School Board, for example, recently decided to eliminate honours high school courses in math and science for so-called equity and inclusion purposes. Special classes for “gifted” students are currently under attack in Canada. John Barsby, who taught mathematics for 37 years, has been retired since 2004.

The Free Library. ![]() If enabled, it will show exactly which colors in the input PNG got matched. Also, for your convenience, we've added the preview mask option. To get rid of these pixels, you can use the edge smoothing option, which mixes the colors of the old and new pixels, making a smooth transition between colors. Just import your PNG image in the editor. You can also adjust the opacity of the fog overlay PNG to be more or less transparent. Worlds simplest online Portable Network Graphics (PNG) color changer. Next, in the layers panel, find the blending mode dropdown menu. Often, pixels of the original color pixels still remain on the border or at the edge of old and new colors. If the fog overlay isn’t adjusted to the size of your image, simply resize the overlay and confirm. It looks at the lightness parameter (geek note: that's "L" in "HSL") of the original pixels and sets the same lightness for the pixels of the new color. To preserve tints, shadows, and gradients in the output PNG, you can activate the "Preserve Color Shades" option. If the similar color match option is set to a value that's greater than 0%, then not only the indicated color is replaced, but also its shades and tones. All pixels of the selected color are immediately replaced with the new color and you can see the effect in the output preview field. The color for the replacement can be specified in the options as a color name, color code, or rgb(r,g,b) function, or you can select it directly from the input image by clicking on a color pixel in the input PNG. For example, you can match 10% of possible green colors, which include sea green, jungle green, and forest green. For example, you can quickly swap red with blue, or yellow with white.
