Tuesday’s Twister #17 – Number Sense (Negatives)

Here’s a puzzle that I introduced back in December called Number Sense Puzzles.  They are geared for younger puzzlers to help them improve their number sense.  Let me first give a general introduction. There will be 8 statements each corresponding to a number.  You have to use the numbers 0 through 9 once and only once to fill in the correct number for each statement.  You will need to use and develop your deductive problem solving skills in order to correctly place the numbers.  Since there are only 8 answers and 10 numbers (0 through 9), some of the answers will require two digits.  In this puzzle, some of the answers will be negative, that’s no problem, just make sure the digits use 0 through 9 once and only once.

I created an interactive puzzle that will automatically check your answer and provide feedback. I also created a pdf file that can be used in classrooms or with pencils for those so inclined. The goal is to have fun and challenge yourself.

Today’s puzzle is all about adding and subtracting negatives. I’ve found that this is an area that gives many students a really difficult time. It looks easy, but remember to take your time so you use each number once and only once!
