<p> Once a dog named Nelly lived on a farm. 1 There were three other dogs on the farm. Their names were Blackie, Whitey, and Brownie. What do you think the fourth dog’s name was? </p><p>Nelly.

The coins are of four different denominations, and she has the same number of each denomination. What are the four denominations, and how many of each does she have? </p><p>Janice has six pennies, six nickels, six dimes, and six quarters. The easiest way to arrive at the answer is to notice immediately that, since the last number in the amount she has is 6, she must have either six pennies or one penny. She can't have just one penny, because then she would have only one each of three other denominations, and that can't add up to $2.46. So she must have six of each denomination. She can't have six silver dollars, because then she'd have more than $2.46. And half-dollars are no longer in circulation. </p><p>Source: Barnes and Noble, Mensa Presents Mind Games for Kids, p.14</p><p>Read this story.

If only one of the following sentences is true, where is Ralph's bone? </p><p>1. The bone is under the rock. 2. The bone is in the garden or under the tree. 3. The bone is under the rock or under the porch. 4. The bone is not in the garden. </p><p>The bone is in the garden. </p><p>If sentence #1 is true, then sentence #3 is also true, but only one sentence can be true, so both #1 and #3 are false-the bone is not under the rock or under the porch. That leaves the garden and the tree, so let's look at sentences #2 and #4. If sentence #2 is true, then sentence #4 is false. That would leave us with just 1 true sentence, but is the bone in the garden or under the tree? We know that sentence #4 is false, so the bone must be in the garden. </p><p>Source: Lowell House, Brain Games, p.60</p><p>Cindy, Andy, and Mia, were all over at A pizza was in the box. 5 Keith's house when a package was delivered.

From the following information, can you tell how athletes A, B, and D placed in the race? </p><p>Athlete A was not last. Athlete A came in after E. Athlete D was not first. </p><p>Since C was third and E was second, A could only be first or fourth. Since A was behind E, A could not be first; therefore A must be fourth. D could not be first, second, third, or fourth, so D must be fifth. If D is fifth, A fourth, C third, and E second, then B must be first. </p><p>Spatial Awareness 7 A.

Place one penny in the middle of the circle. Label it "G." Penny G should end up in a small triangle all by itself. Now divide the circle into sections by drawing three straight lines so that there is only one penny in each section. </p><p>Lateral Thinking </p><p>Can You Explain?
