Weekly Reader Connections

Teacher Guide: Lesson 16.4

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 “Tick-Tock” gives children information about atomic clocks. The world's first atomic clock was developed at the United States Bureau of Measures in 1949. The clock was updated several times, the last time in 1999, when it became accurate to about one second in 20 million years. The article introduces children to the notion that some watches and clocks do not keep time accurately. Children learn that the atomic clock is the most accurate kind of clock.

The Word Wise activity deals with homophones, words that sound exactly the same but are spelled differently and have different meanings. If time allows, you may wish to challenge the children to write sentences for these homophones:

see, sea pear, pair road, rode sun, son

The Data Hunt activity has children practice telling time to the quarter hour by answering multiple-choice questions.
