2 Parents: We are counting on you to help us teach your child these terms/skills. Helping your child learn these terms/skills will greatly accelerate your child s academic achievement. Just do it! You re going to Harvard!

3 CRCT Terms Learned in 3rd Grade Add and subtract decimals Whole numbers/decimal computation Identify angles - scalene, isosceles, equilateral Length, area, weight Number sense

4 CRCT Terms Learned in 3rd Grade Add/subtract fractions with like denominators ⅛ + ⅜ = Data usage/interpretation Characteristics of 2D and 3D shapes Order of operation

5 CRCT Terms Learned in 3 rd Grade Fact Families (See X and Power Points) (Should have memorized these in 3 rd grade) Multiply 2 digits by 2 digits Divide by a 2 digit number Divide a 3 digit number by a single digit number Fractions- proper, improper, mixed number

6 Proper, Improper, Mixed Fractions Proper in which the numerator is less than the denominator 3/4, 5/8 Improper in which the numerator is greater than one or equal to the denominator 4/3, 6/6 Mixed number a whole number plus a fraction 2 ⅛

7 CRCT Terms Learned in 3rd Grade Estimate: an approximate rather than an exact answer to a math problem. Round to nearest 10, 100, 1000 Round decimal to nearest whole number

8 CRCT Fourth Grade Math Concepts, Terms, and Skills

9 CRCT Fourth Grade Terms Numbers and Operations Classify numbers into odd/even numbers Understand factors

10 CRCT Fourth Grade Terms (See May Vocabulary Power Point) Factors the numbers that are multiplied to give a product 1x2=2, 3x5= 15 The factors are 1, 2, 3, and 5.

11 CRCT Fourth Grade Terms Picture Graphs/Venn Diagram (See May Power Point) In math, a Venn Diagram is used to show relationships between sets. In prewriting, it is used to organize thoughts. In language arts, a Venn Diagram is used to compare or contrast 2 subjects, 2 places, 2 things, or 2 people.

12 Venn Diagram Used to Compare and Contrast Factors of 6 and 10 3, 6 1,2 5, 10 1 and 2 are common factors Greatest Common Factor is 2.

13 CRCT Fourth Grade Terms Place Value the value determined by the position of a digit in a number. (e.g. ones, tens, hundreds, thousands, ten thousands, hundred thousand, one million, ) One million Hundred thousand Ten thousands thousands hundreds tens 3, 2 1 1, , 2 1 1, ones

14 CRCT Fourth Grade Terms Decimal point a period put before a decimal fraction. The periods in.5 and.30 are decimal points. Numerator The number above the fraction bar in a fraction. (¾ the numerator is 3.) Denominator - The number below the fraction bar in a fraction. (3/4 the denominator is 4.) Common denominator - ¼, ¾the common denominator is 4.

15 CRCT Fourth Grade Term Measurement (See November Power Point) Measure and compare -inch, foot, yard, centimeter, meter, milliliter, liter, cup, pint, quart, gallon, etc. (See November Power Point) Compute volume using formulas with units of cubic centimeters ( cm ), cubic meter (m 3 3 cubic inch ( in ), and cubic yard (yd ). Protractor an instrument used to draw and measure angles 3 3 protractor

16 CRCT Fourth Grade Terms Geometry ( See December/January Power Points) Understand a parallelogram (e.g. cut it apart and rearrange it into rectangle with the same area) Understand faces, edges, and vertices

17 CRCT Fourth Grade Terms Geometry Geometry Shapes/Plane Figures triangles, squares, rectangles, trapezoid, quadrilateral, pentagon, hexagon (See December Power Point) Irregular Polygons-according to number of edges Vertices (See January PowerPoint) Sizes of angles- right angle, obtuse angle, acute angle (See January Vocabulary Power Point)

18 CRCT Fourth Grade Terms Geometry Polygon - a closed figure made by joining line segments, where each line segment exactly intersects two others Regular polygon- a polygon whose sides are all the same length and has angles all the same Irregular polygons- have different side lengths and different angles (See Irregular Polygons on this CD)

19 Vertex/vertices Vertex- the point at which the sides of an angle meet vertex

20 ray Ray A part of a line that has one end point and goes on and on in one direction.

21 Pentagon a flat shape with five sides. The sum of the angles is 540.

22 Hexagon a shape with six straight sides. The sum of 2 the angles is

23 Trapezoid Trapezoid a 4 sided polygon with only one pair of opposite sides parallel. The sum of the angles is 360.

24 Quadrilateral a figure of four sides and four angles. It is a four sided polygon. The sum of the angles is x 4 sides = 360 quadrilateral quadrilateral 90 90

25 CRCT Fourth Grade Terms Congruent figures that have the same size and shape Arrays- (See September Power Point) Graph- a drawing used to show numerical information. Grid a network of horizontal and perpendicular lines used a a model or representation of something Ordered pairs- a pair of numbers often used to locate a point in a plane.

26 CRCT Fourth Grade Terms Math Symbols - Difference - means to subtract (See September Power Point) % Percent a part of a fraction of a whole expressed in hundredths

27 CRCT Fourth Grade Terms Algebra Represent/investigate the relationships between quantities algebraically Substitute numbers for the unknown Use variables such as (rectangle) or (square) for unknown quantities

28 CRCT Fourth Grade Terms Data Analysis Analyze data presented in a graph Collect, organize and display data using such graphs as circle graph, line graph, bar graph, etc.

29 CRCT Fourth Grade Terms Word Problems Solve word problems using the appropriate math strategy Solve single and multi-step word problems Determine the operations needed to solve the word problems Determine the most efficient way to solve the problem, e.g. mental math, paper and pencil or calculator

30 CRCT Fourth Grade Terms Problem Solving Strategies Brainstorm Make a table Work backward Use or look for a pattern Make a picture or diagram Guess and check Make an organized list Use logical reasoning
