In this Dilations - Scale Factors & Algebraic Representations task cards activity students will write the coordinates of the vertices of each figure & write the algebraic representation that explains the effect of the scale factor on the image dilation.. There are 6 task cards with problems in total. On the last two exercises, students will draw the dilation of a star-shaped figure on a coordinate plane given the scale factor and, in a paragraph, explain the process of dilating a figure
