How to Play Sign Stamp

  1. 1

    Pick a Stall

    Eight signs or survival with three lives. Easy uses one name or place. Hard hangs two or more on the same sign.

  2. 2

    Read the Sign

    Find the words that are names of people, places, days, months, or the word I.

  3. 3

    Stamp the Plate

    Tap a brass letter. Stamp A for a proper noun. Stamp a if it should stay small. Reset puts every plate back to lowercase.

  4. 4

    Clear the Sign

    When every plate is right, the next sign swings in.

Key Features

  • Tap a Brass Letter

    Candidate words wear a brass plate on the first letter. Tap the one you mean. The rest of the word stays readable.

  • Stamp A or a

    The gold A raises a proper noun. The slate a keeps a common noun small. A right stamp scores at once. A wrong stamp shakes and stays put.

  • Score You Chase

    Hits start at +100 and climb with the streak. A clean sign with no misses adds a gild bonus. Best scores save per mode and difficulty.

  • English Stays English

    The signs are English practice sentences. Buttons and labels follow the site locale.

What is Sign Stamp?

Sign Stamp is a capitalization game. Players read a short English sentence on a tin sign and stamp capitals onto proper nouns. Common nouns stay lowercase. The picture of a letter on a plate keeps the choice obvious. Buttons and labels follow the site locale.

Why Play Sign Stamp?

  • 1

    See the Name

    A proper noun is a specific name. Jupiter, Monday, and Sam get a capital. planet, day, and dog do not.

  • 2

    Stamp, Don't Type

    Kids tap a letter and press A or a. No keyboard. Instant pops tell them if the name was right.

  • 3

    A Score That Moves

    Point pops and a streak make capitalization feel like a market shift, not a worksheet.

  • 4

    Touch First

    Plates and stamps are large. Play sits under the sign, never over the sentence.

Frequently Asked Questions

What is a proper noun?

A proper noun names a specific person, place, day, month, or the word I. It takes a capital letter. A common noun names a general thing and stays lowercase.

What happens if I stamp A on a common noun?

That is a miss. The letter stays lowercase. The streak resets. In survival you lose a life.

What does Reset do?

It puts every brass plate back to lowercase so you can stamp the sign again. It does not cost a life.

What do Easy, Medium, and Hard change?

How many proper nouns hang on one sign and how many decoy plates sit beside them.

What grade is this for?

Second through fourth grade, when students learn to capitalize names, places, and the word I. Third grade is the main fit.
