Instructional Arc (10 Minutes)
1
Hook: The Messy Postcard (2 Mins)
Display Slide 2 showing a postcard with run-together writing: July 4 1776 Philadelphia Pennsylvania. Explain that without punctuation, our words collide and get lost! Commas act as visual traffic signs to help readers pause.
2
Modeling & Rules (4 Mins)
Introduce the Date Rule (Slide 3): Place a comma between the day of the month and the year: October 24, 2023. Introduce the Place Rule (Slide 4): Place a comma between the city and state name: Indianapolis, Indiana. Teacher Script: "The comma is like a small hook that keeps the numbers and names from crashing into each other."
3
Guided to Independent Practice (4 Mins)
Distribute the Postcard Punctuation Practice . Guide the class to write today's date in correct format, then their home city and state. Have them swap postcards with a neighbor to verify their comma placements before completing the Quick Check.
Common Misconceptions
Over-commaing: Placing commas before the month (e.g., ,October 24) or between state and ZIP. Keep it simple: only between day/year and city/state!Weak Handwriting: 3rd graders' commas can look like periods. Model drawing a clear comma hook , that sits on the baseline.
Differentiation Strategies
Support: Provide a yellow highlighter to draw comma outlines on student worksheets so they can trace the visual anchor.Extension: Challenge early finishers to write a full address on the mock postcard with correct envelope layout, including the ZIP code.

The Travel Dilemma
What's Wrong with this Postcard?
POSTCARD
"On July 4 1776 the founders met in Philadelphia Pennsylvania to sign a historic letter..."
Punctuation Crash!
Without commas, the day merges into the year (July 41776!) and the city crashes into the state (PhiladelphiaPennsylvania!).
Commas act like safety shields that separate our ideas.
Let's solve this travel trouble! Slide 2 of 5
Rule Number One
Punctuate the Date
1
The Date Rule
Month + Day October 24
,
Year 2023
Always Separate Day & Year
Place the comma directly after the number of the day. This keeps the day numbers from running into the year numbers.
Good Example: July 4, 1776Bad Example: July, 4 1776 (Oops!)
Next up: Putting places in their place! Slide 3 of 5
Rule Number Two
Divide City and State
The Address Divider
When writing a city and state next to each other, put a comma right after the city name.
Good Example: Seattle, WashingtonBad Example: Seattle Washington (Crash!)
2
The Place Rule
City Name Indianapolis
,
State Name Indiana
