I Make Memories That Last a Lifetime

I make memories that last a lifetime,
Without me you’ll be miserable,
If you miss me you can gourge and it’s okay.
Some say I am naturally split in two.

What am I?

Sleep. It’s the time your mind organizes memories and knowledge. Sleep deprivation is miserable (as you well know if you’ve experienced it). If you miss a few nights of sleep, you can sleep more to catch up with no problems. And some believe that segmented sleep, where you sleep, wake for an hour, then go back to sleep, was the dominant form of sleep before the Industrial Revolution.

Moved Like the Tide

Dear Brother,
In the past, men believed
that it moved like the tide.
Till its movement desists,
we will always be this.

Blood.

How Old Is The Shepherd?

There are 125 sheep and 5 dogs in a flock.

How old is the shepherd?

You can’t determine the answer.

I debated adding this riddle because it is less of a riddle and more of an illustration of how kids are (or are not) being taught to think for themselves. But after reading how kids feel the need to make up an answer without understanding why, I thought this could be a good reminder for all of us to exercise our critical thinking skills.

I Always Send You In The Right Direction

I always send you in the right direction,
I’m arrayed in black and white,
Ignore me and lose my protection,
No more than two words are in sight.

What am I?

one-way

A one way street sign. It tells you the correct way to go, is black and white (in the United States), going the wrong way can get you a citation and the sign only has two words on it.

Memory I Have But I Have No Mind

Mouth-less but I will tell you a name that is not mine,
I will show you the years I have seen but I have no eyes,
Memory I have but I have no mind.

What am I?

A gravestone. The stone bears the name of the deceased and the memories and recollections of their life are represented by the grave site.

Wily Winifred and the Case of the Odd Numbers

Mrs. Shine was having a rough day and wanted a break. So she asked her class to calculate the sum of the first 50 odd numbers. In a few moments, Winifred was at her desk with the correct answer of 2,500. Stunned, Mrs. Shine figured she must have gotten lucky, and sent precocious Winifred back to her seat with the task of finding the sum of the first 75 odd numbers. Again, Winifred returned in seconds with the correct answer (5,625).

How did Winifred find the answer so quickly?

Winifred, being the precocious child she is, realized there was a pattern when computing smaller sums of odd numbers.

First 3: 1 + 3 + 5 = 9
First 4: 1 + 3 + 5 + 7 = 16
First 5: 1 + 3 + 5 + 7 + 9 = 25

Do you see the pattern like our dear friend Winnie?

For the first n odd numbers, the sum is equal to n2. Thus the first 50 is 502, or 2,500, and the first 75 is 752, or 5,625.

What am I?

Sum of 22

Fill in numbers such that the sum of each 3-character row is 22 while the sum of all five numbers is 30.

a
bcd
e

The problem works out to a set of three equations:
b + c + d = 22
a + c + e = 22
a + b + c + d + e = 30

Solving for c = 14, leaving d = 8 – b and e = 8 – a. In other words, c must be 14, but the other two numbers just have to add up to 8. The requirement that they be unique rules out 4 + 4, so you’re left to choose from the following combations for b + d and a + e:
0 + 8
1 + 7
2 + 6
3 + 5
