Primary Math Number Mysteries

Do you love a good mystery?

I am less than 100.
I am an odd number.
My tens digit is the same as the number of days in a week.
My ones digit is the number of fingers on one hand.

What number am I?

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.

  1. Great idea! I don't teach primary but I still like your idea. I am sure it could be modified for junior students. Thanks for the inspiration. I am your newest follower.

    1. Hi Sidney - I don't teach primary either. I teach algebra 1, 2. I want to create puzzles for my high schoolers.

      In the summer I tutor ... mostly primary students. So I enjoy making up activities for them.

      Thank you for dropping by and especially for leaving a comment! I just visited your blog and love it.
