How to Play the Place Value Decimal Game

1. Read the Mission
   At the center of the screen, under the text “Find the digit in the…”, you will see a target place value in large, underlined letters (e.g., TENTHS or HUNDREDTHS).
   

2. Identify the Target Digit
   Look at the large number displayed in the middle. Each digit is a button. You must click the button that matches the requested place value. Left of the Dot (Whole Numbers): · Tens: Two digits left of the decimal point. · Ones: The digit immediately to the left of the decimal point. The Decimal Point: Your anchor. It never moves. Right of the Dot (Decimal Parts): · Tenths: The first digit to the right of the dot. · Hundredths: The second digit to the right of the dot. · Thousandths: The third digit to the right of the dot.

3. Check and Score
   · If you are correct: The screen will flash green with a “✓ CORRECT!” message. Your score will go up, and a new number will generate automatically after a second. · If you are wrong: The screen will flash red with “✗ TRY AGAIN”. You can keep trying the same number until you find the right digit. · Progress Bar: Watch the blue line at the very top of the card. It shows your accuracy percentage. If it’s full, you’re a perfect detective!
    
   

Why the “-ths”?
Notice that every name to the right of the decimal point ends in “-ths”. This is a signal that you are looking at a fraction or a “slice” of a whole number.
· Tenths: One whole divided into 10 equal parts.
· Hundredths: One whole divided into 100 equal parts.
· Thousandths: One whole divided into 1,000 equal parts.

An Example: 42.385
Let’s break down the number 42.385:
· 4 is in the Tens place (40)
· 2 is in the Ones place (2)
· 3 is in the Tenths place (0.3 or 3/10)
· 8 is in the Hundredths place (0.08 or 8/100)
· 5 is in the Thousandths place (0.005 or 5/1000)

Peer Tip: There is no such thing as a “Oneths” place. The system starts at Tenths because you are dividing the 1 (the One) into 10 pieces.
