Math Fun Facts for Kids
Playing with numbers and learning fun facts can motivate kids to get involved with math. Teachers might consider posting a fun math fact of the day each morning, particularly ones that requires an interpretation or comparison or are presented as a riddle. The last few minutes at the end of the day can be set aside for discussing the fact.
Amazing 8
Multiplication practice becomes entertaining with the following problem, as posted on the Hartford, Vermont, School District's website:
Sequential Inputs of numbers with 8:
1 x 8 + 1 =
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321
Animal Number Trivia
Some animal number fun facts include the following items:
During hibernation a hedgehog's heart beats only 20 beats per minute; if not hibernating, the rate is 190 beats a minute. Beavers each cut down an average of 200 trees a year. Oysters lay about 500 million eggs a year but only one usually becomes mature. It takes 18 hummingbirds weighed together to make up on ounce. Dogs running in the Iditarod race in Alaska use up 10,000 calories a day. The mammal that sleeps the most hours in a day is the cat; it closes its eyes for an average of 16 hours.
Polygon Fun Facts
Once kids have mastered the names of basic geometric shapes, they might enjoy learning interesting-sounding names for more complicated shapes. A polygon with four unequal sides is called a quadrilateral; however, a polygon with twelve sides and twelve angles is called a dodecagon, and a hexadecagon has sixteen sides. An icosagon has twenty equal sides.
Number Names
Number names are fun facts for kids to learn. From a million to a billion to a trillion, kids can move on to all the prefixes which follow in that series (quadrillion, quintillion, sextillion and so on). After they've learned these, it's fun to learn the word googol and talk about what that number looks like (1 followed by 100 zeroes).
Word Guess
Ask kids to guess how many words the average 6-year-old understands, and then ask them to guess how many words the average high school graduate knows.
Answer: Six-year-olds know about 13,000 words; high school grads know about 60,000.
