The following two exercises were suggested for second-graders to help them explore the idea of reflection. The additional part for you in both cases is first to predict where the mirror line is and to explain why you predict that mirror line will produce the number of dots shown.t (a) Place a mirror on or near the three circles shown below in such a way that you can see the numbers of circles shown. (i) Six Circles (ii) Five Circles (iii) Four Circles @
