## Teacher Guide: Lesson 20.5

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

The article “Moooving In!” tells students about a miniaturized cow that is so small, it can be kept as a house pet. Zebu cows are revered in India, where they are allowed to walk through the streets untethered. Call on students to read aloud the article. (They will enjoy elongating the “oo” sound in the words to emulate the mooing.)

The Word Wise activity reviews the definitions of synonym and antonym. The synonyms of “puny” that appear in the article are “tiny,” “small,” and “mini.” You may wish to elicit the meanings of words in which “mini-” is used as a prefix, such as “miniature” and “minimum.” Students will be able to list several antonyms of “puny,” such as “big,” “large,” “huge,” “great,” and “enormous.”

Students subtract with mixed numbers in order to answer these questions in the Data Hunt activity.

1. How much taller is Pal than Smiley?
Answer: 2 , or 2 inches
2. How much taller is Winner than Chippy?
Answer: 1 , or 1 inches

Note: You may wish to point out that miniature horses are bred both as pets and for show. Explain that horses' heights are typically measured in “hands.” (A “hand” is equal to 4 inches.) A standard horse is about 15 hands. By contrast, a miniature horse is about 7 hands.
