Seven pages for one lesson, sections of a class newspaper, The Comparison Times, built around the question: how does a model help you solve a comparison problem? Page 1 (Headline Hunt) has six news briefs: students underline the comparison, decide whether it is times as many or more or fewer, and write an equation. Pages 2 and 3 (The Equation Desk) read 24 = 3 × 8 as 24 is 3 times as many as 8 and as 24 is 8 times as many as 3, with a tape diagram for each, then caption news graphics and decide which sentence fits a story. Pages 4 and 5 (Money Matters) are the problem Ken has $5, Mark has 3 times as much: bills, a tape diagram, 3 × 5, the total of both boys and an explanation, then two problems to try. Pages 6 and 7 (Reporter’s Notebook) have two classroom articles with comparison phrases to log and solve, then a page for phrases from real books, magazines and news and a news brief of the student’s own. For one class period, print pages 1, 2, 4 and 6; the other pages continue those sections.
Teach page 4 with real or play money: one $5 bill for Ken and three for Mark, then the same thing as a tape diagram on the board. Page 7’s phrase hunt can go home or to the library, with a short share-out the next day.
Look for comparisons in a newspaper, a magazine or a book: twice as many, 3 more than, 5 times as long. Ask what two things are being compared, and whether it is “more than” or “times as many.”

A short newspaper-themed lesson on comparison problems: what 24 = 3 × 8 means and how times as many differs from more than. Students sort headlines, read an equation two ways, solve the Ken and Mark money problem with a tape diagram and find comparison phrases in articles.
