### PRODUCT DESCRIPTION

These hands-on fraction riddles encourage students to visualize fractions, like a logic puzzle. Using the clues, students will build fractional rectangles or arrays using colored squares or tiles. Perfect for 3.NF.1 and 4.NF.1

How can I use this product?
This file contains two formats. One format has each of the 20 riddles on one page so you can display it for a whole class, pause and have each student or group build the rectangle, and then display the next page for the possible answer. The other format has two riddles on one page that can be printed in black and white or color for task cards that can be used as a math center.

NOTE: I do have a Google Version too!

Common Core Standards:
Number and Operations - Fractions
Develop understanding of fractions as numbers.
3.NF.1: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
4.NF.1: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Measurement and Data
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
3.MD.5: Recognize area as an attribute of plane figures and understand concepts of area measurement. a. A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area. b. A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.
3.MD.6: Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
