4th Grade Math TEKSPlace Value: We study place value from the hundredths place all the way up to hundred billions.
Students will be able to model decimals and whole numbers using tenths and hundredths grids.
Students will understand the each place is 10 times greater than the place on it's right, and 1/10 the value of the place on its left.
Student will be able to round whole numbers to a given place through the hundred thousands place.
Students will be able to compare and order whole numbers.
Students will be able to compare and order decimals using models.
Students will be able to write numbers in standard form, word form, expanded form, and expanded notation.Addition and Subtraction of Whole Numbers and Decimals
Students will be able to add and subtract whole numbers and decimals using the standard algorithm. (Students may use manipulatives and blank place value charts if needed. Please note that at this point in 4th grade, some students may still be using alternative methods of addition and subtraction. i.e. visual representation, expanded form)
Students will round to the nearer 10, 100, or 1,000 to estimate solutions.
Students will represent an addition or subtraction problem using a strip diagram and/or equation.
Students will be able to solve word problems related to addition and subtraction.Multiplication
Students will determine products of a number and 10 or 100 using properties of operations and place value understanding.
Students will represent the product of 2 twodigit numbers using arrays, area models, or equations
Students will use strategies and alogorithms to multiply up to a fourdigit number by a onedigit number.
Students will round the nearest 10, 100, or 1,000 to estimate solutions.
Students will solve one and twostep problems involving multiplication.Division
Students will represent the quotient of up to a 4digit whole number divided by a 1digit whole number using arrays, area models, strip diagrams, or equations.
Students will use strategies and algorithms to divide up to a 4digit whole number divided by a 1digit whole number.
Students will round to the nearer 10, 100, or 1,000 to estimate solutions.
Students will solve onestep problems involving division.Problem Solving
Students will solve one and twostep problems using multiplication, division, addition, and/or subtraction.
Students will represent multistep problems with strip diagrams and equations.
Students will represent problems using an inputoutput table to generate a number pattern that follows a given rule.Fractions
Students will compare two fractions with different numerators and different denominators and represent the comparison using the symbols >, =, or <.
Students will represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models.
Students will represent fractions and decimals to the tenths or hundredths as distances from zero on a number line.
Students will determine if two given fractions are equivalent using a variety of methods.
Students will represent fractions using models.Geometry
Students will identify points, lines, line segments, rays, angles, and perpendicular and parallel lines.
Students will identify and draw one or more lines of symmetry, if they exist, for a twodimensional figure.
Students will apply knowledge of right angles to identify acute, right, and obtuse triangles.
Students will classify twodimensional figures based on the presence or absence of parallel or perpendicular lines or the presence or absence of angles of a specified size.Angles
Students will determine the approximate measures of angles in degrees to the nearest whole number using a protractor.
Students will determine the measure of an unknown angle formed by two nonoverlapping adjacent angles given one or both angle measures.Measurement
Students will solve problems related to perimeter and area of rectangles where dimensions are whole numbers.
Students will solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate.
