Below is a listing of math vocabulary found on the E.O.G. Students DO NOT NEED TO SPELL (although that's not a bad thing) these words. They do need to know what they mean. These are vocabulary words we will use throughout the school year. Students need to visit this site often and read over the list while thinking about what it means. Another suggestion is to print this list and check off the words that they can explain. acute triangle addend addition A.M. angle area array bar graph base benchmark number capacity centimeter certain circle closed figure compatible numbers cone congruent figures cube cubic unit cup customary units cylinder decimal decimal point decimeter degrees denominator difference digit dividend division divisor edge elapsed time endpoint equally likely equation equilateral triangle equivalent decimals equivalent fractions estimate even number expanded form face fact family factors foot fraction gallon gram half hour hexagon hour hundredths inch greater than less than isosceles triangle key kilogram length likely line line graph line of symmetry line plot line segment liter mass mean median meter metric units milliliter minute mixed number mode month multiple multiplication net numerator obtuse triangle octagon odd number open figure ordered pair ordinal number ounce parallel lines parallelogram pattern pentagon per perimeter period pictograph pint place value P.M. polygon possible outcomes pound probability product pyramid quadrilateral quart quarter hour quotient range ray rectangle rectangular prism reflection regroup related facts remainder rhombus right angle rotation round scale scalene triangle side similar figure simplest form skip-count sphere square square number standard form subtraction sum survey symmetrical figure tally temperature tenths tessellation 3-dimensional figure time line translation trapezoid triangle 2-dimensional figure unit price unlikely variable vertex volume week weight whole number word form yard year
