December Challenge - Years 3 & 4

One of Santa's elves eats too much breakfast during the holiday season.  He weighs 27 kg, but each morning he gains 4 kg.  He works so hard making toys in Santa's factory each day that he loses 500 g by the evening.  If this pattern continues for 12 days, how much does the elf weigh at the end of the 12 days?

December Challenge - Years 5 & 6

As you are thinking about wrapping up presents this holiday season, this problem might help you choose the right size box.

Start with a 10 by 10 grid.

If you cut out a 1 by 1 square from each corner, it could be folded into an open-top box that had an 8 by 8 base and was 1 square deep. That means that the box would be able to hold 64 cubes.

What size square should you cut out of each corner to make the box that would hold the greatest number of unit cubes?

Another way to ask this question is 'Which box has the greatest volume of space available?'.
