Print and go with full answer keys and a wanted poster set for the wall, no prep, for math centers, morning work, early finishers, homework and sub plans. Students count the groups, read the array and add the same number over and over, each total takes a teacher off the wanted board, and a wrong total matches no clue, so the bridge into multiplication is built without you marking it, from one CSI Mini Mystery Detective download.\u003c\/p\u003e\n\n\u003cp\u003eTwenty identical rows of equal groups is the dullest page in second grade, and hiding them inside a hunt is the only way anyone practices them. The arrays sit beside the groups, which is where the jump to times tables quietly starts, and one case fills a center rotation. Five math pages and one Mystery Detective wanted board cover the block before the first times tables.\u003c\/p\u003e\n\u003cp\u003eStudents count equal groups, read arrays and write repeated addition sentences, then match each total to a clue. The cases move from twos, fives and tens up to threes, sixes and nines. One teacher in the school has turned into a monster, and the totals show who.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Five Cases\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCase 1: twos, fives and tens\u003c\/li\u003e\n  \u003cli\u003eCase 2: the same groups with bigger totals\u003c\/li\u003e\n  \u003cli\u003eCase 3: threes and sevens, with arrays\u003c\/li\u003e\n  \u003cli\u003eCase 4: threes, sixes and nines\u003c\/li\u003e\n  \u003cli\u003eCase 5: fours, sixes, eights and nines mixed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFive cases, each with a problem page and a clue page\u003c\/li\u003e\n  \u003cli\u003eEqual groups, arrays and repeated addition\u003c\/li\u003e\n  \u003cli\u003eA black and white version\u003c\/li\u003e\n  \u003cli\u003eAnswer keys for all five\u003c\/li\u003e\n  \u003cli\u003eWanted posters and a banner\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach case has a problem page and a clue page.
