### Myers' Math Vocab Grade 4

Question | Answer |
---|---|

equilateral triangle | a triangle with all sides the same |

scalene triangle | a triangle with all sides different |

isoceles | a triangle with 2 sides the same and 1 different |

polygon | a closed figure with straight sides; many sides and many angles |

quadrilateral | a figure with 4 sides |

parallel lines | lines that are equidistant apart and will never cross |

perpendicular lines | lines that form a 90 degree angle |

intersecting lines | lines that cross |

congruent | same size same shape |

similar | same shape different size |

coordinates | ex: (5,3) over then up |

round | slip to the side and look for a five....if the number to the right is 5 or higher round up |

estimate | "That's abouuuuut....." quickly round number |

compare fractions | criss-cross multiply from bottom to top and then compare products |

order fractions | compare 2 at a time using criss-cross OR remember close numbers mean large; far apart numbers mean small fraction |

equivalent fractions | fractions that are the same amount but different size pieces ex: 1/2 = 2/4 |

translation | slide |

rotation | turn |

reflection | flip |

symmetry | cut figure in half, fold, and both halves match |

ray | one endpoint and goes on in one direction |

line | set of points that go on and on in both directions |

line segment | part of a line with 2 endpoints |

decimal place value | tenths, hundredths, thousandths |

add/subtract decimals | line up decimals no matter what and +/- normally |

compare decimals | write numbers under each other vertically and fill in zeros; remember that tenths are BIGGEST |

+\- like fractions | add or subtract numerator; leave denominator the same |

prime number | number that only has 1 and itself as factors |

composite number | number that has more than 2 factors; 1 is neither prime nor composite |

long multiplication | lattice or traditional |

variable | an unknown in an equation and is represented by a letter of the alphabet |

likelihood | possible, impossible, likely, unlikely |

probability | chances; can be written as fraction or 1 out of 5 |

area | space inside a figure; count boxes or length x width; label is sq in, sq ft, etc. |

perimeter | distance around figure; add all sides or count unit lengths; label is just cm, in, ft, units |

volume | Space inside a 3D solid; l x w x h; label is cubic ft, cubic in, cubic units |

fractions on number line | numerator and denominator close together--closer to 1 and far apart--closer to 0 |

line graph | display data; shows increases (ups) and decreases (downs); EX: temperatures |

bar graph | display data; good for comparing; need title, labels, bars, number scale |

median | the number in the middle of a set of data that is in least to greatest order |

mode | the number you see the MOST in a set of data that is in least to greatest order |

range | greatest minus least |

ordered pairs | found on a coordinate grid; over then up or x number then y number; found in parentheses |

2D | figures that have length and width; sides, corners |

3D | solid figures that have length, width, and height; faces, edges, vertices |

place value | going left--ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions |

order decimals | write all numbers under each other vertically and line up decimals; fill in holes with zeros |

line plot | uses Xs to show data; holes are empty, clumps have a lot of Xs in one area |

factors | numbers you multiply together in multiplication problem |

multiples | like products; answers to multiplcation |

measure length | customary: in, ft, yd metric: mm, cm, m, km |

measure capacity | customary: cup, pint, quart, gallon metric: milliliters,liters |

measure mass | customary: ounces, pounds, tons metric: grams and kilograms |
