50 free 1st Grade Math trivia questions with answers — science & nature quiz, new questions added Oct 2026.
First grade is where math stops being a counting song and becomes something a child can use. Sums and take-aways get a method, bigger numbers get broken into parts, and the clock on the wall starts to make sense. This quiz follows what a first grader in the US, or a Year 1 pupil in the UK, meets across the year: adding and subtracting small numbers, counting in equal steps, place value, comparing numbers, telling the time, days and months, coins, equal shares, and flat and solid shapes. Every question hangs the sum on something real, from spider legs and bowling pins to chopsticks and piano keys, so the numbers always stand for things a child can picture. It works as a warm-up for a first grader, a quick check for a parent or teacher, or a family game in which the grown-ups may learn something too. Each answer comes with a short explanation that shows the working and adds a surprising detail.

Q 01A spider has eight legs and an ant has six: how many legs do the two animals have altogether?
14
14 legs is the total, because 8 + 6 = 14. Counting legs is the quickest way to tell the two apart: spiders have eight, while ants and all other insects have six.
Q 02A strike in ten-pin bowling knocks down every pin with the first ball: how many pins stay standing?
0
0 pins are left standing, because 10 − 10 = 0. Bowlers mark a strike with an X on the score sheet, and three strikes in a row is known as a turkey.
Q 03A full round of golf is two sets of nine holes, one after the other: how many holes altogether?
18
18 holes make a full round, because 9 + 9 = 18. The number was settled at St Andrews in Scotland in 1764, when the course there was cut down from 22 holes.
Q 04Which six-sided shape do honey bees build again and again to make the wax cells of a honeycomb?
Hexagon
Hexagon cells fit side by side with no gaps between them. Many wasps build the same six-sided pattern, but they make it out of paper instead of wax.
Q 05Which US coin is worth ten cents, even though it is the smallest and thinnest coin in circulation?
Dime
Dime coins are tiny but mighty: each one is smaller than a penny or a nickel, yet worth more than those two coins put together.
Q 06At the Olympic Games, gold goes to first place and silver to second: which place wins bronze?
Third
Third place wins bronze, the last of the three medals. Some sports, such as boxing and judo, hand out two bronze medals in every event.
Q 07Which day of the week comes right after Tuesday and is named for the Norse god Odin?
Wednesday
Wednesday began as 'Woden's day', after the Old English name for Odin. In German the same day is simply called Mittwoch, which means mid-week.
Q 08A haiku poem has three lines of five, seven and five syllables: how many syllables altogether?
17

Q 09A cricket batter on 99 runs scores one more run: what score, known as a century, is that?
100
100 runs make a century, a landmark score that cricketers also call a ton. Adding one to 99 is the first time a count needs three digits.
Q 10Chopsticks are used in pairs of two equal sticks: how many chopsticks are there in four pairs?
8
8 chopsticks make four pairs: count by twos to get 2, 4, 6, 8. People have been eating with chopsticks for more than three thousand years.
Q 11A common clover has three leaves and a lucky clover has four: how many leaves on one of each?
7
7 leaves is the total, because 3 + 4 = 7. Lucky clovers are rare: a survey of millions of clovers found only about one four-leaf plant for every 5,000 ordinary ones.
Q 12A standard guitar has six strings and a violin has four: how many strings is that altogether?
10
10 strings is the total, because 6 + 4 = 10. A twelve-string guitar sounds fuller because every one of its six strings has been doubled.
Q 13On a piano, each octave has seven white keys and five black keys: how many keys is that in all?
12
12 keys fill each octave, because 7 + 5 = 12. The same pattern of long and short keys repeats again and again from one end of the keyboard to the other.
Q 21Which number is made of 3 tens and 6 ones, the same as the number of inches in a yard?
36
36 is 3 tens and 6 ones. A yard is also the same length as 3 feet, and medieval English law measured it against an iron bar kept for the king.
Q 22Which number has 6 tens and 4 ones, the same as the number of spaces on a chessboard?
64
64 is 6 tens and 4 ones. The board has eight rows of eight, a size one medieval book of games called ideal: bigger boards were too tiring and smaller ones too quick.
Q 23Which of these numbers is greater than 31, the number of days in the month of December?
34
34 is greater than 31: both have 3 tens, but 34 has more ones. December takes its name from the Latin word for ten, because it was once the tenth month of the Roman year.
Q 14A soccer team starts a match with one goalkeeper and ten outfield players: how many players is that?
11
11 players start for each side, because 10 + 1 = 11. The rules only name the goalkeeper, so a coach may arrange the other ten in any pattern.
Q 15A tic-tac-toe grid has three rows with three spaces in each row: how many spaces are there in all?
9
9 spaces fill the grid, because 3 + 3 + 3 = 9. When both players make their best moves, a game of tic-tac-toe always ends in a draw.
Q 16An octopus has eight arms: how many arms do two octopuses have when counted together?
16
16 arms is the total, because 8 + 8 = 16. Every octopus also has three hearts, one for its body and one for each of its two gills.
Q 17A young child grows ten baby teeth along the top and ten along the bottom: how many teeth is that?
20
20 baby teeth make a full set, because 10 + 10 = 20. The tiny buds that grow into them start forming months before a baby is born.
Q 18A dartboard has sections scoring from 1 to 20 points: which score is one less than the highest?
19
19 is one less than 20. The numbers are scattered around the board to punish poor aim, an idea often credited to an English carpenter in 1896.
Q 19Most starfish have five arms: how many arms would you count on three starfish with five arms each?
15
15 arms is the total: count by fives to get 5, 10, 15. Not every starfish stops at five, though, and some species grow many more arms.
Q 20A decade is a period of ten years: how many years are there in four decades?
40
40 years make four decades: count by tens to get 10, 20, 30, 40. The word decade comes from an Ancient Greek word for a group of ten.
Q 24Which number comes just before 30 and is the number of days February has in a leap year?
29
29 comes just before 30 when counting. February only stretches that far in a leap year, and its extra day at the end is called the leap day.
Q 25An hour lasts 60 minutes: how many minutes are there in half an hour?
30
30 minutes is half of 60, because 30 + 30 = 60. Splitting the hour into 60 parts is an idea handed down from the ancient Sumerians.
Q 26A watch's long hand points up at 12 and the short hand points at 3: what time does the watch show?
3 o'clock
3 o'clock is the time, because the short hand names the hour. Whenever the long hand points straight up, a brand-new hour is just beginning.
Q 27Which month comes right after June and is named in honour of the Roman leader Julius Caesar?

Q 29A dozen eggs is a box of twelve: how many eggs are there in half a dozen?
6
6 eggs is half of twelve, because 6 + 6 = 12. Twelve is a handy size for a box because it also splits evenly into threes and fours.
Q 30A professional basketball game in the NBA is split into quarters: how many equal parts is that?
4
4 equal parts make up the game, and each quarter in the NBA lasts 12 minutes. American college men's games are split into two halves instead.
