Αντιγραφή του Multiplying Non-Zero Integers
This applet assigns the product of two non-zero integers (-6 < a < 6, -6 < b < 6) to the point (a,b). This creates a grid of products in four quadrants, with the first and third representing positive products and the second and fourth representing negative products. This foreshadows the mapping rules of transformations and the signs of the trigonometric ratios.
Students will reveal the products, one by one, and build their own tables on the worksheet, preferably using two colors.... Leggi tutto 17 November 2019, 5:41am
