Are you smarter than a 5th Grader?
Here’s our version of the new TV game show, juiced up with math terms you should know if you got your middle-school diploma! First look at the words, then scroll down for the definitions and see if you got them right!
- cardinal number
- scientific notation
- scalene triangle
- stem and leaf plot
- unit rate
- prime factorization
The purpose of the meme is to get to know everyone who participates a little bit better every Thursday. Visiting fellow Thirteeners is encouraged! If you participate, leave the link to your Thirteen in others comments. It’s easy, and fun! Be sure to update your Thirteen with links that are left for you, as well! I will link to everyone who participates and leaves a link to their 13 things. Trackbacks, pings, comment links accepted!
How well did you do?
- congruent: Figures or angles that have the same size and shape.
- cardinal number: one, two, three, etc.
- scientific notation: a very convenient way to write large or small numbers and do calculations with them. It also quickly conveys two properties of a measurement that are useful to scientists—significant figures and order of magnitude.
- obtuse: Any angle that measures between 90º and 180º.
- polyhedron: A three-dimensional solid that is bounded by plane polygons.
- heptagon: a polygon having seven angles and seven sides.
- scalene triangle: a triangle with no two sides of equal length
- stem and leaf plot: In a stem-and-leaf plot each data value is split into a “stem” and a “leaf”. The “leaf” is usually the last digit of the number and the other digits to the left of the “leaf” form the “stem”. The number 123 would be split as: stem = 12 / leaf = 3
- addends: Any of a set of numbers to be added.
- divisor: a number by which another number, the dividend, is divided.
- dividend: a number that is to be divided by a divisor.
- unit rate: A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. Common unit rates are miles (or kilometers) per hour, cost per item, earnings per week, etc. In each case the first quantity is related to 1 unit of the second quantity.
- prime factorization: Calculation of all prime factors in a number.
Example:The prime factors of 84 are 7 x 3 x 2 x 2.
