PRODUCT DESCRIPTION

Decimal Detectives includes 16 higher order thinking puzzles designed to challenge and engage your high flyers and fast finishers. Your students will utilize critical thinking and problem solving skills while building a deep and solid understanding of decimals. Each of the 16 activities offers an interesting, non-routine way to explore essential math concepts and skills.

Each Decimal Detective riddle provides a series of 5-6 mathematical clues. Students use the clues to determine the value of the mystery decimal. While the focus of each activity is decimals, the 16 riddles include a variety of upper elementary math skills, concepts, and vocabulary to promote integrated learning and challenge. For example, riddle #11 reads:

• 2/3 of the digits are less than 5.
• The digit in the ten’s place = the number of sets of parallel sides in a trapezoid.
• The number is > 0.5 x 103, but < 0.06 x 104.
• The digit in the hundredth’s place is ¼ the value of the digit in the tenth’s place.
• The product of the digits in the ten’s and one’s place = 0.
• The digit in the thousandth’s place = 8 x 3 – 7 x 3.

The focus is on decimals, yet students also need to apply multiplication with base ten numerals, fractions, geometry, academic math vocabulary, and the order of operations in order to solve this riddle.

The 16 activities are provided in three different formats:
• No-Prep Printables: There are four 8.5 x 11 pages with 4 riddles on each page.

• Task Cards: The sixteen cards are formatted 4 to a page. Cards can be laminated and used as task cards or cut apart and glued into math journals or interactive notebooks.

• Cooperative Learning Cards: There are 16 cooperative learning card sets. Each set is made up of one decimal Detective riddle. The clues are separated onto four different cards. Each member of the group is given one card, or one piece of the puzzle. Students then work together to reach the solution.

The three different formats are included to help you adapt this resource to best meet the needs of your students and instruction. With so many activity options, use the table of contents to print only what you need.
