Students encounter comma-separated lists in the song lyric that reads "Water, food, and shelter," providing an example of commas used to separate single words in a series. The writing prompt on "The Most Important Room" page asks students to complete the sentence "We use this room for ______________, ______________, and ______________," which requires students to write three items in a list separated by commas and an "and." These elements give students opportunities to read and write examples of single-word series separated by commas.

Students read and hear sentences that model commas separating single words in a series, for example: "Wetlands, grasslands, woodlands, and deserts are types of habitats." Students also see the series in the closing song: "Plants, insects, and animals," which provides an additional auditory and visual model of commas in a list.

Students encounter multiple written lists that use commas to separate single words, for example "cats, dogs, sheep, cows, and horses" and "fish, snakes, lizards, and birds." Students also see a series of pet-care actions (feeding, brushing, playing, walking, giving the pet a bath) presented as separate items that model a list of single-word/short-phrase elements.

The lesson includes the sentence "Discuss temperature, precipitation, and sky conditions," which models commas separating items in a series. Students are asked to generate lists of words or items in activities (for example the Rain Acrostic where students produce words for R, A, I, N, and the materials lists for crafts), giving occasions where items in a series are recorded.

The lesson text contains explicit sentences that use commas to separate items in a series, e.g., "March, April, and May are the months of spring." and "Flowers, fruits, and vegetables grow from seeds planted in the soil." The student poems also include commas in lines such as "Rain, rain go away," showing commas in printed text for students to see.

Students read explicit examples of commas separating single words in a series, for example the Facts and Definitions sentence stating June, July, and August are the months of summer. Students also encounter season lists separated by commas in the song (Winter, spring, summer, fall) and word boxes that present multiple words in a row (beach, hot, trip, swim, pool).

The example paragraph in Activity 4 models a series using commas: "I could sound the alarm, slide down the pole, and drive the fire truck." The "When I Grow Up" worksheet prompt "I would like being a ___________ because I could ___________, ___________, and ___________." presents a written template that separates three items with commas. Students are asked to write or dictate sentences about community workers (Activity 5), giving opportunities to produce short lists or series in their own writing.

The lesson text contains multiple examples of single-word lists separated by commas (e.g., "People with character demonstrate respect, responsibility, kindness, and honesty" and the Skills list that separates traits with commas). The wrapping-up Life Application asks students to "record each of the character traits" in four boxes, which could lead students to list words for traits. Students are also asked to write or copy sentences in several activities (retelling The Boy Who Cried Wolf, handwriting K words), providing opportunities to produce sentences that might include lists.

The lesson text includes several lists where single words are separated by commas (for example, the attributes list: "size, shape, texture, color, magnetic or not, and density" and the answer key lists: "Liquids: pond, rain, syrup, lotion, tap water" and "Solids: washcloth, ice cube, salt and pepper, marbles, snowflakes"). Students are asked to write definitions and brainstorm examples (cutting and pasting or labeling "Solids" and "Liquids" sheets), which could produce lists of examples similar to those shown.

The lesson contains multiple examples of single-word item lists separated by commas (e.g., "Sweet: candy, cookies, cake, Kool-Aid" and "Bitter: tea, olives, broccoli, grapefruit, unsweetened chocolate"). Activity 2 instructs students to "record the names of the four foods she selected," which leads students to list single-word food names on the chart. The Student Activity Page and Activity 3 ask students to categorize and record foods into columns, providing occasions to produce lists of single-word items.

The student activity pages present lists of senses written with commas (e.g., "see, hear, smell, taste, and touch" and "hear, see, taste, smell, touch"), so students encounter commas separating single words in a series in printed materials. Activity 4 asks students to write or copy a sentence about the nature walk, giving an opportunity for written practice. The nature-walk and 'How Many Senses?' pages require students to record and list observations, which could involve writing multiple items.

The introduction models a sentence that uses commas to separate adjectives in a series: "It is red, delicious, smooth, hard, crunchy, and juicy." Students are asked to record sensing words on a blank sheet and to think of one sensing word, phrase, or sentence for each of the five senses, which provides occasions to generate lists of single words. Students also write or dictate sentences about popcorn and fill-in sensory words in the report, offering opportunities to produce multiple descriptive words in sequence.

The Student Activity Page's sample 'Supplies' lists items such as "paints, paper, cookies, a CD player, and flowers," which shows single words/phrases separated by commas. The instructions ask students to choose a date and time and to make invitations that list place, date, and time, which has students write dates and lists. The Party Planner prompts students to record supplies and ideas in list form for each sense.

Activity 1 instructs students to use the color word (or the first letter of the color word) to show the pattern and gives the explicit example "Y, R, Y, R." This requires students to write single words or letters separated by commas to represent a series. Activity 3 has students write or copy a sentence, offering a chance to write but not explicitly tied to comma use.

The "Words to Practice" section presents the phrase "shape, color, and size," which uses commas to separate single words in a series. It instructs an adult to model writing each word and has the child practice writing them, providing at least one written example students can copy.

The student pages display number lists with commas (for example the label "2. 1, 2, and 3" appears in the activity and instructions). Students are asked to write number patterns and fill in sequences (Activity 1 and Activity 2), so they encounter sequences of numbers written adjacent to one another on the pages.

Students are prompted to fill a sentence that reads "This pattern is made up of __________, __________, and __________," which models a three-item series with commas and an "and" before the final item. Several activity pages require students to list or describe multiple pattern elements in sequence (e.g., First to Eighth lines and the A B C sections) where blanks are presented in a list format. The prompt to mark out the line before "and" for two-item patterns shows students manipulate the series structure.

The Student Activity Page explicitly lists the words "Slap, Clap, Tap," showing single words separated by commas. Activity 2 asks students to copy the words at the top of the page or record patterns, which requires writing or reproducing the comma-separated series. Activity 4 asks students to write about a sound pattern, giving a context in which students might write lists of sounds.

The Sound, Rhyming, and Story pattern script pages include prompts phrased as "It is made of ______________, ______________, and ______________," which present a list of single words separated by commas and an 'and' before the final item. Multiple activity pages ask students to list the elements of a pattern using the three-slot format, modeling the conventional series structure. The student script pages require students to write or dictate those lists as part of preparing their video scripts.

The lesson includes teacher-provided lists that use commas to separate single words, for example: "Possible Answers: water, wind, machines, animals." The Skills section also shows examples written with commas separating items (e.g., "headings, tables of contents, glossaries, electronic menus, icons"). The Using an Index activity asks students to copy sentences from the book, which may expose them to punctuation in context.

Students encounter and are asked to list plant needs presented in comma-separated form (e.g., "Sunlight, water, dirt, space, and air"). The facts section also lists plant parts with commas ("Plants have roots, stems, leaves, and sometimes flowers, fruits, or vegetables"). Students are asked to list the parts of a plant on handwriting paper, which could require writing single-word series.

Students encounter commas separating single words in explanatory text such as "Physical change is a change in size, shape, color, or state of matter." Students also see the phrase "solid, liquid, and gas," which models commas in a three-item series. These examples provide instances where commas are used to separate single words in a series.

The lesson text contains at least one sentence that demonstrates commas separating items in a series: "She has pictures hanging up everywhere, books scattered, fishing poles all around, and a half-finished wood carving of a bear." Several activity pages present lists of items (e.g., titles, characters, problems, solutions) that model listing multiple elements, showing commas used in printed examples of series.
