MINI MATH PUZZLES

This math worksheet is a great way to discover if the children have trouble with their weights and measurements. It's great for 3rd grade through adults! (maybe some really smart 2nd graders as well) The order of operation comes into play on a couple of the examples. I use the word PEMDAS to remind the kids that the order you do the math is parenthesis, exponents, multiplication, division, addition, and subtraction.

1. Multiply the # of legs on an octopus times the number of sides on a triangle. Next, add the # of legs on an ant to the answer and subtract the # of wheels on 8 unicycles. Finally, subtract the # of quarts in a gallon. What’s the answer?

2. Multiply the # of sides of a pentagon times the # of days in the week and add the # of months in a year. Next, subtract the # of wheels on four bicycles and and subtract the # of hours in a day. What’s the answer?

3. Multiply the # of legs on a spider times the # of sides on a quadrilateral. Next, add the # of degrees in a circle and subtract the # of seconds in a minute. Finally, subtract the # of ounces in a pound. What’s the answer?

4. Multiply the # of inches in a foot times the # of years in a decade. Next, add the # of days in a non-leap year and subtract the # of days in December. Finally, subtract the # of eggs in 3-dozen eggs. What’s the answer?

5. Multiply the # of feet in a mile by the # of years in a century. Next, divide your answer by the # of pints in a quart and subtract the # of days in a leap year times a century. Then subtract the # of eyes on 10,000 people. What’s the answer?

6. Multiply the # of ounces in a cup times the # of months it takes to have a normal baby and subtract the # of wheels on 5 tricycles. Next, add the # of horns on 20 unicorns and subtract the # of days in November. What’s the number?


ANSWERS KEY

1. 8 X 3 + 6 – 8 – 4= 18
2. 5 X 7+12-8 –24 = 15
3. 8 X 4 + 360 – 60 – 16 = 316
4. 12 X 10 + 365 – 31 – 36 = 418
5. 5,280 X 100 divided by 2 – (2 x 10,000) = 207,400
6. 8 x 9 – 15 + 20 – 30 = 47
