Place Value Mysteries

Place Value Mysteries is a Grade 4 reasoning activity where students solve hidden numbers from a set of place-value clues. Clues may refer to digit positions, comparisons, products, or number patterns, and students combine the information until only one number fits. The activity turns place value into a logic problem rather than a direct identification task.

Use it for partner work when students are ready to justify how several clues work together. After solving an example, students can create their own mystery numbers and trade them with classmates, which adds both problem design and mathematical language.
