They each had their favorite animal, but they all stayed together for the day and left when the zoo closed at 5:00. Please identify the person, their favorite animal feeding, and the time based on the clues below. 1. Nancy, a Clemson fan, made it clear she was only there for the tiger feeding. 2. She had to wait until two hours after the sea lion feeding. 3. The koala feeding almost put her to sleep two hours before the last feeding of the day. 4. Teresa was fascinated by the hawks. 5. Marilyn got so close to her favorite feeding she got splashed by water; her clothes were still damp when they went to the Australia exhibit.

Please identify the giraffe, their native country, and their height based on the clues below. Please note that you cannot use the photos to decide about their heights because they were taken at different times, places, and distances.

1. Zakita is 1 foot shorter than the giraffe from Tanzania. 2. Morutana came from Somalia. 3. The one that is 10 feet tall is either the giraffe from Botswana or Jebedah. 4. The giraffe from Tanzania is 1 foot shorter than Angrit. 5. The 12 foot tall giraffe is from Chad.

Each selected one exhibit (the aquarium, the bird aviary, the mammal trail, or the reptile serpentarium) to inspire their art (clay sculpture, digital photography, pencil sketches, and watercolor painting). Can you match the artist, their media, and their inspiration?

1. Zoo visitors kept looking over Charlie’s shoulder at the sketches.

2. The watercolor artist thought her work portrayed the shimmering scales of the reptiles quite well.

3. Avery never went anywhere near the aviary; she read that some parrots like to eat clay.

4. Dorothy’s digital photos caught her subject’s bright colors and the shapes of their wings in flight.

5. One of the pencil sketches of a shark won honorable mention at the state fair that fall.

]]><![CDATA[Logic Puzzle: Pet Shop Girls]]>Sun, 22 Jan 2017 05:00:00 GMThttp://rsd2-spark.weebly.com/critical-mathematical-thinking/logic-puzzle-pet-shop-girlsThree friends, Cindy, Lisa, and Tanya, wanted to get pets. Their parents agreed they were responsible enough to adopt one animal each and drove them to the rescue center to meet the animals.

After playing with several animals, each friend chose a different type of animal from the others--a cat, a dog, and a parrot. They gave them three names--Fluffy, Rex, and Tutu, but not necessarily in that order.

1. The girl who adopted the dog did not name it "Tutu." 2. Lisa's pet, "Fluffy," does not have feathers. 3. Rex, who is not a dog, was adopted by Tanya. 4. The parrot was not adopted by Cindy.

Can you identify the friend, the type of pet, and the pet's name? You are welcome to use the sprites on Scratch or the Google Drawing table to help make your deductions.

]]><![CDATA[Logic Puzzle: Time and Talents]]>Sun, 15 Jan 2017 05:00:00 GMThttp://rsd2-spark.weebly.com/critical-mathematical-thinking/logic-puzzle-time-and-talentsThree siblings are all musically and physically talented. Each child has a private music lesson and a private sports lesson each day. Music lessons are offered at 3:30, 4:00, and 5:30 pm at the conservatory, while sports lessons are offered at the field house at 4:30, 5:00, and 6:00 pm.

Betty's saxophone lesson is 60 minutes earlier than Nadine's tennis lesson, but Betty's swimming lesson is 30 minutes later than Nadine's trumpet lesson. Also, Everett's guitar lesson is earlier than Nadine's tennis lesson, and Everett's golf lesson is 60 minutes earlier than Nadine's music lesson.

Can you help get the children to their practices in time by identifying the children, lessons, and times correctly?
