Five detective cases play out aboard a pirate ship, so it drops straight into Talk Like a Pirate Day on September 19, a pirate theme week, a treasure hunt or buried gold unit, a Treasure Island or pirate book study, an ocean and under the sea topic, or Halloween week when you want swashbuckling adventure instead of something spooky. No cutting, no gluing, no technology, and completely no prep - just print and go.\u003c\/p\u003e\n\u003cp\u003eThe five cases climb. The first is plain two digit addition with no carrying at all, the middle cases start regrouping the ones into a ten, and the last two push the answers past 100 so students carry twice. That gives you a whole differentiated ladder inside one pack - the same mystery for the group still learning to line up the columns and the group ready to cross a hundred. Black and white, ink friendly, PDF, with a full answer key for every case.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdding two 2-digit numbers with no regrouping, so the column method is secure before any carrying starts\u003c\/li\u003e\n  \u003cli\u003ePages that mix carrying and non-carrying problems, so students have to look at each column instead of carrying out of habit\u003c\/li\u003e\n  \u003cli\u003eRegrouping the ones into a ten on every problem, the classic two digit addition with regrouping page\u003c\/li\u003e\n  \u003cli\u003eRegrouping the tens into a hundred where the ones column never carries - the case that catches out anyone who learned carry when you add\u003c\/li\u003e\n  \u003cli\u003eBoth columns regrouping, with sums well past 100\u003c\/li\u003e\n  \u003cli\u003eLining digits up by place value in a vertical column addition layout\u003c\/li\u003e\n  \u003cli\u003eFull answer keys for every case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFive cases to crack: The Empty Gold Chest, The Stolen Wheel, The Vanished Parrot, The Bare Flagpole and The Silent Cannon.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is a Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA no-prep detective activity where students solve math problems to cross off suspects and unmask the culprit.
