Numbers & Operations
Clues to Add How many in all? What is the total? What is the sum? How many altogether? How many
combined?
Clues to Subtract What is the difference? How many more? How many are left? How much longer,
shorter, taller, heavier? How much change?
Denominator the bottom number of a fraction – tells how many parts there are
Difference the answer you get when you subtract
Double a number twice 12+12=24 or 12x2=24
Estimate to find a number that is close to an exact amount by rounding
Equivalent having the same value – equal
Factor a number multiplied
Half to divide into 2 equal groups 14 ÷ 2 = 7
Mixed Number a whole number and a fraction Example 2 3/Numerator the top number of a fraction – tells how many parts are shaded
Product the answer you get when you multiply
Quotient the answer you get when you divide
Round to replace a number with one that tells about how much or how many
Sum the answer you get when you add
Approximately about, estimate

Year 365 days 52 weeks 12 months
Geometry
Angle two rays that have the same endpoint
Acute – an angle whose measure is between 0 and 90 degrees
Right – an angle whose measure is exactly 90 degrees
Obtuse – an angle whose measure is between 90 and 180 degrees
Straight – an angle whose measure is exactly 180 degrees
Complementary angles 2 angles whose measures have a sum of 90 degrees
Cone a solid figure with 1 circular face, 0 edges, and 0 vertices Ex. a party hat
Congruent figures that have the same shape and size
Cube a solid figure with 6 square faces, 12 edges, and 8 vertices Ex. a box
Cylinder a solid figure with 2 circular faces, 0 edges, and 0 vertices Ex. a roll of paper towels
Equilateral triangle a triangle with 3 equal sides, angles measure 180 degrees
Heptagon a polygon with 7 sides
Hexagon a polygon with 6 sides
Intersecting lines lines that cross at one point
Isosceles triangle a triangle with exactly 2 equal sides, angles measure 180 degrees
Line a straight path of points that goes on forever in two directions
Line segment part of a line that includes two endpoints
Line of symmetry the fold line in a symmetrical figure
Octagon a polygon with 8 sides
Parallel lines lines that never cross and stay the same distance apart
Pentagon a polygon with 5 sides
Perpendicular lines two lines that intersect to form square corners or right angles
Point an exactly point in space
Quadrilateral a four sided polygon, angles measure 360 degrees

Reflection the change in position of a figure by flipping it over a horizontal or vertical line
Right triangle a triangle that has a right angle
Scalene triangle a triangle with no equal sides, angles measure 180 degrees
Similar figures that have the same shape, but not the same size
