Cootie Catchers Math is an interactive and motivating tool for daily skill review. Using a new twist on
the popular origami fortune tellers, this hands-on resource provides a fun and unique approach to
practicing and reviewing standards-based math concepts and academic language. Cootie Catchers
Math features 20 reproducible cootie catchers that each reinforce a specific math skill. Each page
includes a Before You Flip hint for students to apply while they use each cootie catcher and an After You
Flip activity to extend their learning after they have finished. Once the cootie catcher is made, students
read and solve the problems, then they lift the flaps to reveal the correct answers. A recording sheet is
provided on the inside back cover to help teachers keep track of assigned cootie catchers.
Aligned to the National Council of Teachers of Mathematics (NCTM) standards, Cootie Catchers Math is
an ideal resource for providing specific content review for all students. Research shows that repetition
is essential for the brain to learn and recall information. Furthermore, children have a tendency to
repeat activities they enjoy. Cootie Catchers Math offers a fun and quick way for students to repeat and
retain essential skills. This teacher-tested, student-approved resource can be used for classroom center
activities, as enrichment assignments when regular class work is completed, or for homework. Perfect
for individuals, partners, or small groups, Cootie Catchers Math makes practicing math skills enjoyable.
The following areas are addressed in this resource:
✽ Number patterns
✽ Time
✽ Addition
✽ Money
✽ Subtraction
✽ Algebra
✽ Place value
✽ Geometry
✽ Fractions
✽ Problem solving
Cootie catchers fit in pants pockets, backpacks, or lunch boxes for review on the go! Students can use
them in a classroom center, at their desks, on the playground, or in a car or bus. Parents can slip cootie
catchers into a pocket or purse and use them to review with their child at home, in line at the store, or
while waiting for appointments. With these easy-to-make, fun-to-use, portable manipulatives, students
will love reviewing math skills and vocabulary the Cootie Catchers Math way!

How to Use
1. Select a skill you would like your students to practice, and make multiple copies of the corresponding page. Store
the pages in a labeled hanging file in a math center or where math manipulatives are stored.
2. Demonstrate how to fold the cootie catchers. Display the instructions for students’ reference.
3. Remind students to read the Before You Flip section before using each cootie catcher.
4. Have the students complete the After You Flip activity as an extension or quick assessment after they have
used each cootie catcher. Ask the students to return the top portion of the page to you. Use this, along with the
recording sheet, to keep track of assigned cootie catchers.
5. Send the cootie catchers home for additional practice.
