Students are prompted to check comma usage in the editing rubric, which asks "Do I use commas correctly?". Students are directed to consult a "Handy Guide to Writing" that explicitly notes when to use a comma and provides rules with examples. Students are instructed to edit and proofread their drafts and to correct punctuation during revision and final copy stages.

Students are prompted during Editing (proofreading) to "correct misspelled words and grammar and punctuation errors," indicating they will check punctuation. The Folktale Rubric asks students to evaluate whether they "use commas correctly?", which requires students to apply comma rules when revising. The materials direct students to refer to the "Handy Guide to Writing for any grammar or punctuation rules you're not sure about," providing a resource for punctuation guidance.

The lesson text explicitly states "You know that commas separate items in a series," and the teacher-facing opening to the activity reminds students of this rule. Students are given dialogue that includes the sentence "He handed me the vines showed me how to weave and watched as I tried to do it," which in the answer key is corrected to "He handed me the vines, showed me how to weave, and watched as I tried to do it." Students are instructed to add commas to the dialogue, so they encounter at least one example of commas separating items in a series.

The writing rubric under "Mechanics" explicitly asks, "Do you use commas correctly with items in a series, in direct address, and when starting a sentence with 'yes' or 'no'?" Students are instructed to write a rough draft, then revise/edit with attention to mechanics, and to review the rubric before drafting. The lesson emphasizes mechanics as part of evaluation, signaling that students are expected to attend to comma use in their own writing.

The Things to Know section explicitly states "Use commas to separate items in a series" and gives an example sentence (I packed toothpaste, a toothbrush, pajamas, and an outfit...). Activity 2 (More Commas) lists Rule 1 as using commas in a series and provides multiple sentences where students must insert commas (e.g., I asked for a remote control car a telescope and a new pair of tennis shoes). The activity also asks students to write original sentences that follow each comma rule, and the Parent Plan supplies model answers showing correct comma placement in series.

Students read an answer that lists multiple gifts separated by commas: "A blue and white scarf Barbara knitted, a sewing wife with its needles, and pins and a thimble from Uncle." Students are asked to make lists of reasons in the "Should I Stay or Go?" activity, which requires producing multiple items in a list format.

Students are prompted to use commas in letter format: the directions state to "Use a comma after the person's name" in the greeting and to "Use a closing remark followed by a comma." The sample letter shows commas used in the greeting and closing ("Dear Caleb," and "Lovingly,"). The rubric explicitly asks "Do I use commas correctly?" under Mechanics, which directs students to consider comma usage when editing.

Activity 2: Adding Punctuation directs students to review comma rules and gives eight sentences for students to add missing punctuation. One sentence (item 7) requires commas to separate items in a series; the answer key shows the corrected form with commas: Maria's small stockings, her slips, and her nightgowns. The activity includes a reference to the Handy Guide to Writing (p. 32) for rules on commas.

Activity 2 instructs students to "review the rules for comma and quotation marks that you practiced in this unit." Option 1 asks students to cut sample sentences from newspapers or magazines that "fit each rule," and Option 2 asks students to match sentences to comma or quotation mark rules. Parent notes reiterate that the student will find and/or match sentences that follow the comma rules reviewed in the unit.

Students are asked to identify sentence fragments and rewrite them as complete sentences in Activity 2, giving them opportunities to produce full sentences. One example sentence shown in the parent checks is "We had history, poetry, and plays," which correctly uses commas to separate items in a series. The vocabulary activity asks students to write sentences using listed words, which could produce sentences that include lists.

Students encounter a clear example of items in a series in Activity 1: "The fields stretched like a carpet of jewels, emerald, topaz, and garnet," which uses commas to separate the items. Students are asked to write three descriptive sentences about their painting and to write a paragraph about a weather-related day, providing opportunities to produce lists or series in their own writing.

Students see a list of character names separated by commas in the "Things to Review" section (Kit, Matthew Wood, William, John, Mercy, Judith, and Hannah Tupper). Students are asked in Option 2 to "Make a list of what you need to do, and order your list," and the "On Trial" activity asks students to produce three arguments with support, which requires generating multiple listed items.

The 'Things to Know' section lists vocabulary terms in a comma-separated series: "Know these vocabulary terms: trepidation, dais, temporal, resilience, talisman, sadist, arrogance, annihilate, ominous, and imperceptible." The Vocabulary Crossword student page includes a word bank that presents multiple words in a single listed sequence, showing commas and list formatting in context.

Students are given a paragraph to edit that includes the sentence with three names run together: "Megs, Charles Wallaces and Calvins mission was in danger." Students are instructed to edit for plurals, -ed/-ing endings, and transitions, and the parent answer key provides a corrected version showing commas: "Meg, Charles Wallace, and Calvin's mission was in danger." The editing activity asks students to rewrite the paragraph with corrections, requiring them to apply punctuation changes in their rewrite.

Students encounter several written lists that use commas to separate items, for example the components of creativity listed as "fluency, flexibility, elaboration, and originality" and the story elements listed as "protagonist, antagonist, setting, theme, and problem/solution." The lesson also asks students to organize many ideas for their short story, presenting those elements in a comma-separated series in the directions.

Students are instructed to "Combine sentences using appositive phrases with commas," and example answers show commas used with appositives (e.g., "Abraham Lincoln, the sixteenth president, was..." ). One combined example lists three items separated by commas: "The Civil War was fought between the Confederate, the states in the south, and the Union."

Students encounter sentences and lists that use commas to separate items, for example: "Lemurs eat leaves, different kinds of fruit, eggs, and some types of insects." Students also see short lists presented as comma-separated items (e.g., "Geographical location, Diet, Description of lemur habitats") on the activity pages.

The bibliography instructions list specific punctuation roles (for example: place of publication followed by a comma, publisher's name followed by a comma, year followed by a period) and provide formatted citation examples such as Smith, James. All About Lemurs. New York, Millins House, 2004. Several other sample citations (encyclopedia, article, website) show items separated by commas in the citation fields. Students are directed to use the Sample Bibliography format and to list source elements in the specified order with commas between elements.

Students are told in Activity 3 to "check to see that you used commas and quotation marks correctly when they were needed," which directs them to attend to comma usage during editing. Students read and model sample sentences that contain comma-separated lists, for example: "most are herbivores that survive on fruits, flowers, and leaves." The Student Activity Page also shows list-like items (e.g., "Laws, Programs, Involvement") that exemplify items presented in series.
