TX. 111.5. Grade 3, Adopted 2012.

3.2. Number and operations. The student applies mathematical process standards to represent and compare whole numbers and understand relationships related to place value. The student is expected to:

3.2 (C) Represent a number on a number line as being between two consecutive multiples of 10; 100; 1,000; or 10,000 and use words to describe relative size of numbers in order to round whole numbers.

3.3. Number and operations. The student applies mathematical process standards to represent and explain fractional units. The student is expected to:

3.3 (A) Represent fractions greater than zero and less than or equal to one with denominators of 2, 3, 4, 6, and 8 using concrete objects and pictorial models, including strip diagrams and number lines.

3.3 (B) Determine the corresponding fraction greater than zero and less than or equal to one with denominators of 2, 3, 4, 6, and 8 given a specified point on a number line.

3.3 (C) Explain that the unit fraction 1/b represents the quantity formed by one part of a whole that has been partitioned into b equal parts where b is a non-zero whole number.

3.5. Algebraic reasoning. The student applies mathematical process standards to analyze and create patterns and relationships. The student is expected to:

3.5 (A) Represent one- and two-step problems involving addition and subtraction of whole numbers to 1,000 using pictorial models, number lines, and equations.

3.6. Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional geometric figures to develop generalizations about their properties. The student is expected to:

3.6 (A) Classify and sort two- and three-dimensional solids, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on attributes using formal geometric language.

3.6 (C) Determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row.

3.7. Geometry and measurement. The student applies mathematical process standards to select appropriate units, strategies, and tools to solve problems involving customary and metric measurement. The student is expected to:

3.7 (A) Represent fractions of halves, fourths, and eighths as distances from zero on a number line.

3.7 (B) Determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems.

3.7 (C) Determine the solutions to problems involving addition and subtraction of time intervals in minutes using pictorial models or tools such as a 15-minute event plus a 30-minute event equals 45 minutes.

3.7 (D) Determine when it is appropriate to use measurements of liquid volume (capacity) or weight.

3.7 (E) Determine liquid volume (capacity) or weight using appropriate units and tools.

3.8. Data analysis. The student applies mathematical process standards to solve problems by collecting, organizing, displaying, and interpreting data. The student is expected to:

3.8 (B) Solve one- and two-step problems using categorical data represented with a frequency table, dot plot, pictograph, or bar graph with scaled intervals.
