Baby Giraffe Gets A Name, Kopano

After five days of online voting that drew more than 10,000 votes, the public has spoken: the Dallas Zoo’s new baby giraffe will be named “Kopano,” meaning “united” in Botswana.
The calf was gently introduced to the outdoor feeding yard habitat over the weekend. But starting Monday, he will make regular afternoon appearances outdoors, weather permitting. The giraffe keepers will keep a close eye on temperature, wind and rain to ensure that he remains safe and healthy.

Extend your math lesson with a mini-research lesson using Pebblego. Ask your librarian for your login/password and go to, search "giraffes". The section includes video, "fun facts", habitat, life cycle, food and related articles. You could even look for other African animals and do some comparing based on Diana's excellent questions about giraffes. Have the learners make their own math questions based on what they learn. Better yet, sign up your librarian to do the mini-research/math lesson for you!
