Addition Puzzles that Practice - Complete with SmartBoard Module!
Note: this is a "zip" file that contains both a PDF and SmartBoard file: when you expand it, you will end up with two separate files, one with the PDF of "Reindeer Rescue" for you to print and use, as well as a SmartBoard "notebook" file that you can use interactively.
"Reindeer Rescue" is a truly "hands on" approach to working with addition and subtraction, with links to patterns and problem solving. The basic puzzle is simple: using the numbers 1- 6, distribute them around a triangle so that each side adds up to 9 (thus, trapping the turkey in the pen!) Where it gets really cool is this: you can arrange those same 6 numbers to add up to 10, 11, and 12 on each side.
A SmartBoard notebook file with moveable numbers for the puzzle is included, so you can demonstrate and solve with the rest of your class.
But the fun doesn't end there: you can differentiate this by using the numbers 2 - 7, and each side adding up to either 12, 13, 14 or 15. In fact, you can use any set of 6 consecutive numbers and using the handy "Do It Yourself" sheet customize this for with ANY set of numbers you want. If you work with older students, you can use positive and negative numbers, fractions, decimals, even algebraic expressions.
Included in this packet: the basic "reindeer themed" puzzles in color a; recording sheets (so you can laminate and use the puzzles over and over again), cut-out "Santa hats" with numbers on them, so the students can move the numbers around on the board until they get the correct answer.
There's also an extension where your students can record whether the numbers used on each side were on the "corners" or "interior." By doing this, you'll see a pattern that can help them predict how puzzles with larger numbers will work.
I've also included a page that clearly documents 11, yes, 11 different ways this activity could be differentiated starting in Kindergarten and going all the way up to high school. In fact, I've had high school students write papers about the algebra found in this problem.
I love using these puzzles with my kids; I bet you will too!
