What RL.3.9 Means in Plain English
Third graders compare two books by the same author about the same characters, like two books in a series. They look past the familiar faces and ask three things: where each story happens, what happens in it, and what lesson each book teaches.
In 2nd grade (RL.2.9) students compared versions of the same story by different authors or cultures, like Cinderella tales. Third grade keeps the author and characters fixed. In 4th grade (RL.4.9) students compare themes and patterns, like the quest, across cultures.
RL.3.9 I Can Statements
- I can compare the settings of two books in a series.
- I can compare what happens in two books in a series.
- I can tell whether two books in a series share a theme.
RL.3.9 Worked Example
Two excerpts from an invented series about the same two friends. The comparison has to cover theme, setting and plot.
From Book 1, Juno and Bix and the Parade Llama: The llama on the petting-zoo float slipped its rope halfway down Main Street. Juno took off after it, yelling. Bix stayed put, grabbed a bunch of carrots from the snack cart, and held them out.The llama stopped, sniffed, and trotted straight back to Bix. Juno came back out of breath. “Okay,” she said. “Your way was faster.”From Book 3, Juno and Bix in the Corn Maze: The sun was going down, and every path looked the same. This time it was Bix who wanted to run. Juno grabbed his sleeve. “Wait. Listen.”Far off, the hayride tractor rumbled. They walked toward the sound, slow and steady, and stepped out of the maze just as the lights came on.
Common Mistakes with RL.3.9
Comparing the characters only
“Both books have Juno and Bix.”
Try this: Point out that a series always shares characters, then require one sentence each on theme, setting and plot.
Comparing props instead of plots
“One has a llama and one has corn.”
Try this: Ask what problem each book’s characters face and how they solve it, then compare those two answers instead of the props.
Listing only similarities
“They are both funny and they both have a problem.”
Try this: Use a chart with alike and different columns, and require at least two entries in the different column before discussing.
