One of the many approximations of Pi is the Gregory-Leibniz series (image source Wikipedia):

Here’s a simple Python script which generates math exercises for kids. It uses the Century Schoolbook font which is said to be well readable and LaTeX’s longtable. I just ran some tests, generating 24’000 lines on 2000 pages was no deal at all.
#!/usr/bin/python
# coding: utf-8
import random
import os
min = 1 # number to start with
max = 10 # maximum number
count = 24 # 12 fit on one page
with open('Aufgaben.tex', 'w') as texfile:
texfile.write("\\documentclass[15pt,ngerman]{scrartcl}\n")
texfile.write("\\usepackage[utf8]{inputenc}\n")
texfile.write("\\usepackage{tgschola,longtable}\n")
texfile.write("\\usepackage[T1]{fontenc}\n")
texfile.write("\\setlength{\\parindent}{0pt}\n")
texfile.write("\\pagestyle{empty}\n")
texfile.write("\\renewcommand*{\\arraystretch}{1.5}\n")
texfile.write("\\begin{document}\n")
texfile.write("\\huge\n")
texfile.write("\\begin{longtable}{cccp{8cm}c}")
for i in range(count):
a = random.randint(min, max)
b = random.randint(min, max)
result = a + b;
texfile.write('%s &+ &%s &= &%s \\\\ \\hline\n'%(str(a),str(b),str(result)))
texfile.write("\\end{longtable}\n")
texfile.write("\\end{document}\n")
os.system("pdflatex Aufgaben.tex")
os.startfile("Aufgaben.pdf") # this line may not work under Linux |
#!/usr/bin/python
# coding: utf-8
import random
import os
min = 1 # number to start with
max = 10 # maximum number
count = 24 # 12 fit on one page
with open('Aufgaben.tex', 'w') as texfile:
texfile.write("\\documentclass[15pt,ngerman]{scrartcl}\n")
texfile.write("\\usepackage[utf8]{inputenc}\n")
texfile.write("\\usepackage{tgschola,longtable}\n")
texfile.write("\\usepackage[T1]{fontenc}\n")
texfile.write("\\setlength{\\parindent}{0pt}\n")
texfile.write("\\pagestyle{empty}\n")
texfile.write("\\renewcommand*{\\arraystretch}{1.5}\n")
texfile.write("\\begin{document}\n")
texfile.write("\\huge\n")
texfile.write("\\begin{longtable}{cccp{8cm}c}")
for i in range(count):
a = random.randint(min, max)
b = random.randint(min, max)
result = a + b;
texfile.write('%s &+ &%s &= &%s \\\\ \\hline\n'%(str(a),str(b),str(result)))
texfile.write("\\end{longtable}\n")
texfile.write("\\end{document}\n")
os.system("pdflatex Aufgaben.tex")
os.startfile("Aufgaben.pdf") # this line may not work under Linux
With little modification one can also generate substraction exercises:
#!/usr/bin/python
# coding: utf-8
import random
min = 1
max = 12
count = 24
import os # for sys calls
with open('Aufgaben.tex', 'w') as texfile:
texfile.write("\\documentclass[15pt,ngerman]{scrartcl}\n")
texfile.write("\\usepackage[utf8]{inputenc}\n")
texfile.write("\\usepackage{tgschola,nicefrac,longtable}\n")
texfile.write("\\usepackage[T1]{fontenc}\n")
texfile.write("\\setlength{\\parindent}{0pt}\n")
texfile.write("\\pagestyle{empty}\n")
texfile.write("\\renewcommand*{\\arraystretch}{1.5}\n")
texfile.write("\\begin{document}\n")
texfile.write("\\huge\n")
texfile.write("\\begin{longtable}{cccp{8cm}c}")
for i in range(count):
b = random.randint(min, max)
a = b + random.randint(1, 9)
result = a - b;
texfile.write('%s &- &%s &= &%s \\\\ \\hline\n'%(str(a),str(b),str(result)))
texfile.write("\\end{longtable}\n")
texfile.write("\\end{document}\n")
os.system("pdflatex Aufgaben.tex")
os.startfile("Aufgaben.pdf") |
#!/usr/bin/python
# coding: utf-8
import random
min = 1
max = 12
count = 24
import os # for sys calls
with open('Aufgaben.tex', 'w') as texfile:
texfile.write("\\documentclass[15pt,ngerman]{scrartcl}\n")
texfile.write("\\usepackage[utf8]{inputenc}\n")
texfile.write("\\usepackage{tgschola,nicefrac,longtable}\n")
texfile.write("\\usepackage[T1]{fontenc}\n")
texfile.write("\\setlength{\\parindent}{0pt}\n")

texfile.write("\\begin{document}\n")
texfile.write("\\huge\n")
texfile.write("\\begin{longtable}{cccp{8cm}c}")
for i in range(count):
b = random.randint(min, max)
a = b + random.randint(1, 9)
result = a - b;
texfile.write('%s &- &%s &= &%s \\\\ \\hline\n'%(str(a),str(b),str(result)))
