Our math resources sometimes lack enough practice for students to build independent math skills.
Number Mysteries is a free resource with eight place value mysteries that could be used as extra practice for seat work or a math center.
In Number Mysteries, students identify a 2-digit number using clues. Clues involve common numbers such as “half of a dozen” or the “value of a nickel.”
Students could be asked to represent the mystery number using concrete materials, drawings, or in standard form.
After working through these exercises, students should create their own puzzles. Student-created puzzles with illustrations could be put together in puzzle books and/or hung in math centers to challenge classmates.
