Don't let these brain teasers frost you!

 Solve the puzzles in the back of your Inking About Thinking journal. Always add the date and title of the problem. 


 Evaluate each problem that you complete. How did it make you think? 

3- A snap!  5- Got it once I thought about it  8- AHA! I persevered and finally got it. 10 - Tah Dah! I can't believe I solved it!)








SOCK IT TO 'EM MATH PROBLEMS ... in honour of Albert Einstein who was born on March 14,1879. This brilliant physicist never wore socks!



Read the article " Why Einstein Stopped Wearing Socks".

Record the answer and 5 other interesting facts you did not know about this quirky famous physicist. 




Start with three pairs of socks. Now mix them up so that no mismatched pair is the same as another mismatched pair.


Now try it with four pairs of socks. Is there more than one way to do it?








You are about to leave for holiday, but you forgot your socks! You race back to your room, but all the lights are off , so you can't see the colour of the socks. Never mind, because you remember that in your drawer are ten pairs of white socks, ten pairs of black socks, and eleven pairs of blue socks. You can only take one sock from the drawer at a time. How many of your socks do you need to take before you can be sure you have at best one matching pair?
