FOURTH GRADE MATH CURRICULUM The primary focus of Math in the Archdiocese of Kansas City in Kansas is to promote in our students their problem solving abilities, which are among God’s many gifts.

Generate a repeating and growing pattern. (Read Exo 25:40 for pattern definition) 5. ▲Solve one-step equations using whole numbers with one variable and a whole number solution that: a. Has the unknown in a multiplication or division equation b. Has the unknown in a money equation c. Has the unknown in a time equation involving whole minutes, hours, days, and weeks with values through 200 e.g. 180 minutes = y hours. 6. Compare two whole numbers from 0 through 10,000 using the equality and inequality signs. 7. ▲Represent and describe mathematical relationships between whole numbers 0 through 1,000 using concrete objects, pictures, written description, symbols, equations, tables, and graphs. 8. ▲Find the values, determine the rules, and state the rules using symbolic notation with one operation of whole numbers from 0 through 200 using a horizontal or vertical function table (input/output machine, T-table). 9. ◊Use a function table to identify, plot, and label the ordered pairs in the first quadrant of a coordinate plane. 10. Use mathematical models to represent mathematical concepts. Models include but are not limited to multiplication arrays, hundred charts, base ten blocks, pattern blocks, fraction strips, coins, T-tables, and unifix cubes. 11. ◊Explain and use variables to represent unknown whole number quantities. Standard 3: Geometry Teacher note: The term “geometry” comes from the Greek words meaning, “earth measure.” The process of learning to measure at the early grades focuses on what property (length, width, height) is to be measured and to make comparisons. The student will: 1. Describe solids (cubes, rectangular prisms, cylinders, cones, spheres, triangular prisms) using the terms faces, edges, and vertices as found in Church architecture. 2. Recognize, investigate, draw, and describe plane figures (circles, squares, rectangles, triangles, ellipses, rhombi, octagons, hexagons, pentagons). 3. Recognize a. Squares, rectangles, rhombi, parallelograms, trapezoids as special quadrilaterals. b. Similar and congruent figures c. Points, lines (intersecting and parallel), line segments, and rays. 4. ▲Identify the plane figures (circles, squares, rectangles, triangles, ellipses, rhombi, octagons, hexagons, pentagons, trapezoids) used to form a composite figure. 5. ▲Select, explain, and use measurement tools for a given situation to measure a. Length, width, and height to the nearest fourth of inch or to the nearest centimeter. b. Volume to the nearest cup, pint, quart, gallon; to the nearest liter, or to the nearest whole unit of a nonstandard unit. c. Weight to the nearest ounce or pound or to the nearest whole unit of a nonstandard unit of measure. d. Temperature to the nearest degree. e. Time including elapsed time. 6. ▲Estimate to check whether or not measurements and calculations are reasonable. 7. Describe a transformation using cardinal points or positional directions e.g. go north three blocks and then west four blocks. 8. ▲Recognize, perform, and describe one transformation (reflection, rotation, translation) on a two-dimensional figure or concrete object. 9. ▲Identify and plot points as whole number ordered pairs in the first quadrant of a coordinate plane. 10. Identify and draw rays; parallel, perpendicular, intersecting lines; radius and diameter of a circle, various angles. 11. ◊Recognize and describe solids. 12. ◊Convert within the customary system to solve real-world problems. 13. ◊Convert within the metric system. 14. ◊Recognize three-dimensional figures. 15. ◊Plot ordered pairs in the first quadrant of a coordinate plane. 16. ◊Find the perimeter and area of 2-dimensional figures. Standard 4: Data The student will: 1.

Graphs b. Pictographs with a symbol or picture representing one, two, five, ten, twenty-five, or one-hundred including partial symbols c. Frequency tables (tally marks) d. Horizontal and vertical graphs e. Venn diagrams or other pictorial displays; (Shall/ shall nots of Ten commandments) f. Line plots; g. Charts and tables; h. Line graphs; i.

Minimum and maximum values, b. Range, c. Mode, d. Median when the data set has an odd number of data points, e. Mean when the data set has a whole number mean. 4. Collect data using different techniques (observations, polls, surveys, etc.) and explain results. 5. ◊Recognize that the probability of an impossible event is zero and that the probability of a certain event is one. 6. ◊List all possible outcomes of a simple experiment or simulation including the use of concrete objects. 7. ◊Recognize and state the probability of a simple event in an experiment e.g. when a coin is flipped, the probability of landing heads up is ½ and the probability of landing tails up is ½. This can be read as one out of two or one half. 8. ◊Interpret and use data to make reasonable inferences and predictions. ◊ Essential prerequisite skill ▲Assessed math indicator for KSDE
