Practise 3-digit place value with this mystery number guessing activity. Students read three clues about the hundreds, tens and ones digits, then work out the mystery number and record each digit in the correct place value column.
The clues combine straightforward digit facts with reasoning based ones (e.g. "my tens digit is half of my hundreds digit" or "I am larger than 600"), so students need to think through the relationships between digits rather than just reading them off.
What's included:
10 mystery number slides, each with 3 clues about the hundreds, tens and ones digits
A place value chart answer slide for each mystery number, showing the digit in its correct column
