## Teacher Guide: Lesson 11.5

The Weekly Reader Connections feature on Kids' Place Houghton Mifflin Math provides children with additional information about the topics that appear in the Curriculum Connection feature in their student books.

The article “Listening to Elephants” tells how scientists recorded, and later interpreted, the sounds made by African elephants in the wild. Call on children to read the article aloud.

If time permits, you may wish to share these facts with children:

1. The African elephant is the largest animal that lives on land. African elephants can weigh up to 16,000 pounds.
2. An elephant's trunk contains more than 40,000 muscles. The trunk is used to smell, breathe, touch, eat, drink, and bathe.
3. An angry or frightened elephant can run about 25 miles per hour.

Make sure that children understand the meaning of alphabetical order. Then, let them complete the Word Wise activity, which calls for them to alphabetize words that begin with the same letter by comparing the second letters.

For the Data Hunt activity, children are asked to write pairs of numbers which, when rounded to the nearest ten, give a sum of about 30. Here are some possible combinations:

1. nine eating commands and 21 trick commands
2. 23 eating commands and eight trick commands
3. 18 eating commands and 11 trick commands
4. 12 eating commands and 17 trick commands
