GRADE 3 MATH CURRICULUM
NUMBER AND OPERATIONSUnderstand and use number notation and place value Students Will: Read and write numbers to 10,000 in both numerals and words. Identify the place value of a digit in a number. Compare and order numbers up to 10,000. Count in steps, and understand even and odd numbers Students Will: Count orally by 6’s, 7’s, 8’s, and 9’s starting with 0. Know that even numbers end in 0, 2, 4, 6, or 8. Add and subtract whole numbers Students Will: Add and subtract fluently two numbers through 999 with regrouping and through 9,999 without regrouping. Estimate the sum and difference of two numbers with three digits, and judge reasonableness of estimates. Use mental strategies to fluently add and subtract two-digit numbers. Multiply and divide whole numbers Students Will: Use multiplication and division fact families to understand the inverse relationship of these two operations. Recognize situations that can be solved using multiplication and division and write mathematical statements to represent those situations. Find products fluently up to 10 times 10; find related quotients using multiplication and division relationships. Find solutions to open sentences, using the inverse relationship between multiplication and division. Mentally calculate simple products and quotients up to a three-digit number by a one-digit number involving multiples of 10. Solve division problems involving remainders. Problem-solving with whole numbers Students Will: Given problems that use any one of the four operations with appropriate numbers, represent with objects, words, and mathematical statements; solve. Understand simple fractions, relation to the whole, and addition and subtraction of fractions Students Will: Understand that fractions may represent a portion of a whole unit that has been partitioned into parts of equal area or length. Recognize, name, and use equivalent fractions with denominators 2, 4, and 8, using strips as area models. Place fractions with denominators of 2, 4, and 8 on the number line. Understand that any fractions can be written as a sum of unit fractions. Recognize that addition and subtraction of fractions with equal denominators can be modeled by joining or taking away segments on the number line. MEASUREMENT Measure and use units for length, weight, temperature, and time Students Will: Compare the relative size of one cubic inch to one cubic foot, and one cubic centimeter to one cubic meter. Recognize equivalences of 1 liter, 1,000 ml, and 1000 cubic cm. Know unites of volume and use their abbreviations. Convert ;units of length, weight, area, volume, and time using easy manipulated numbers. Understand meaning of area and perimeter and apply in problems Students Will: Know the definition of area and perimeter and calculate the perimeter of a square and rectangle given whole number side lengths. Use square unites in calculating area by covering the region and counting the number of square units. Distinguish between units of length and area. Visualize and describe the relative sizes of one square inch and one square centimeter. Problem solving involving measurement Students Will: Add and subtract lengths, weights, and times using mixed units within the same measurement system. Add and subtract money in dollars and cents. Solve applied problems involving money, length, and time. GEOMETRY Recognize the basic elements of geometric objects Students Will: Identify points, line segments, lines, and distance. Identify perpendicular lines and parallel lines in familiar shapes. Identify parallel faces of rectangular prisms in familiar shapes. Name and explore properties of shapes Students Will: Identify, describe, compare, and classify two-dimensional shapes. Explore and name three-dimensional solids Students Will: Identify, describe, build, and classify familiar three-dimensional solids. Represent front, top, and side views of solids built with cubes. DATA AND PROBABILITY Use bar graphs Students Will: Read and interpret bar graphs in both horizontal and vertical forms. Read scales on the axes. Solve problems using information in bar graphs, including comparison of bar graphs.
