Mr. FOSTER (for himself, Ms. BONAMICI, Mr. CARSON, Mr. CASTEN, Mr. 
COHEN, Mr. FLEISCHMANN, Ms. KAPTUR, Ms. MCCOLLUM, Mr. MULLIN, 
Ms. RIVAS, and Ms. STEVENS) submitted the following resolution; which 
was referred to the Committee on Science, Space, and Technology 
RESOLUTION 
Expressing support for designation of March 14, 2025, as 
‘‘National Pi Day’’. 
Whereas the Greek letter (Pi) is the symbol for the ratio of 
the circumference of a circle to its diameter; 
Whereas Pi is an irrational number, which will continue infi-
nitely without repeating, and has been calculated to over 
202 trillion digits; 
Whereas Pi is a fundamental mathematical constant that has 
been studied throughout history and is central in mathe-
matics as well as science and engineering; 
Whereas mathematics and science are a critical part of chil-
dren’s education;

Whereas aptitude in mathematics, science, and engineering is 
essential for a knowledge-based society; 
Whereas, according to the 2023 Trends in International 
Mathematics and Science Study (TIMSS) survey done by 
the National Center for Education Statistics, American 
children in the fourth and eighth grades were out-
performed by students in other countries including Singa-
pore, South Korea, Taiwan, and Japan; 
Whereas Black and Hispanic students and students from 
schools with high poverty rates have lower than average 
scores on the TIMSS survey; 
Whereas boys in fourth and eighth grades had higher scores 
than girls in math and science on the TIMSS survey, in-
dicating a gender gap beginning early in their education; 
Whereas the United States needs to reinforce mathematics 
and science education for all students in order to better 
prepare children for the future and to succeed in a 21st- 
century economy; 
Whereas the National Science Foundation has been driving 
innovation in math and science education at all levels 
from elementary through graduate education since its 
creation 75 years ago; 
Whereas mathematics and science can be a fun and inter-
esting part of a child’s education, and learning about Pi 
can be an engaging way to teach children about geometry 
and attract them to study science and mathematics; and 
Whereas Pi can be approximated as 3.14, and thus March 
14, 2025, is an appropriate day for ‘‘National Pi Day’’: 
Now, therefore, be it 
Resolved, That the House of Representatives—

(1) supports the designation of a ‘‘Pi Day’’ and 
its celebration around the world; 
(2) recognizes the continuing importance of the 
National Science Foundation’s math and science 
education programs; and 
(3) encourages schools and educators to observe 
the day with appropriate activities that teach stu-
dents about Pi and engage them about the study of 
mathematics.
