2017 Description: enVisionmath2.0 Grade 3 2017 Grade 3 Learning Centers for Students Topic 1: Understand Multiplication and Division of Whole Numbers 1-1: Multiplication as Repeated Addition Multiplication as Repeated Addition: Visual Learning Curriculum Standards: Use repeated addition to show the relationship between multiplication and addition. Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each (e.g., describe context in which a total number of objects can be expressed as 5 × 7). Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays and measurement quantities (e.g., by using drawings and equations with a symbol for the unknown number to represent the problem). The student will represent multiplication and division through 10 × 10, using a variety of approaches and models. The student will create and solve single-step practical problems that involve multiplication and division through 10 x 10. The student will create equations to represent equivalent mathematical relationships. Represent multiplication facts by using a variety of approaches, such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line and skip counting. Represent division facts by using a variety of approaches, such as repeated subtraction, equal sharing and forming equal groups. Recognize the relationship between multiplication and division. Solve real-world and mathematical problems involving multiplication and division, including both 'how many in each group' and 'how many groups' division problems. Use multiplication and division basic facts to represent a given problem situation using a number sentence. Use number sense and multiplication and division basic facts to find values for the unknowns that make the number sentences true. Represent multiplication facts by using a variety of approaches, such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line and skip counting. Interpret the factors as representing the number of equal groups and the number of objects in each group. Illustrate and explain strategies including arrays, repeated addition, decomposing a factor, and applying the commutative and associative properties. Represent, interpret, and solve one-step problems involving multiplication and division. Solve multiplication word problems with factors up to and including 10. Represent the problem using arrays, pictures, and/or equations with a symbol for the unknown number to represent the problem. Interpret products of whole numbers. Describe in words or drawings a problem that illustrates a multiplication or division situation. Use multiplication and division within 100 to solve problems.

Use strategies and algorithms based on knowledge of place value and equality to fluently add and subtract multi-digit numbers. Understand a fraction as a number on the number line and represent fractions on a number line diagram. Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line. (e.g., Given that b parts is 4 parts, then 1/b represents 1/4. Students partition the number line into fourths and locate 1/4 on the number line.) Instructional Note: Fractions in this standard are limited to denominators of 2, 3, 4, 6, and 8. Understand a fraction as a number on the number line and represent fractions on a number line diagram. Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line. (e.g., Given that a/b represents 3/4 or 6/4, students partition the number line into fourths and represent these fractions accurately on the same number line; students extend the number line to include the number of wholes required for the given fractions.) Instructional Note: Fractions in this standard are limited to denominators of 2, 3, 4, 6, and 8. Using a number line, explain that the numerator of a fraction represents the number of lengths of the unit fraction from 0. Represent fractions on a number line. Understand the whole is the interval from 0 to 1. Understand the whole is partitioned into equal parts. Understand a fraction represents the endpoint of the length a given number of partitions from 0. Relate area to the operations of multiplication and addition. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. Find the area of two-dimensional figures by counting total number of same size unit squares that fill the shape without gaps or overlaps. Find the area of a rectangle with whole-number side lengths by tiling without gaps or overlaps and counting unit squares. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving problems, and represent whole-number products as rectangular areas in mathematical reasoning. Demonstrate that tiling a rectangle to find the area and multiplying the side lengths result in the same value. Multiply whole-number side lengths to solve problems involving the area of rectangles. Represent multiplication facts by using a variety of approaches, such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line and skip counting. Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each (e.g., describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8). Interpret quotients of whole numbers. Relate area to the operations of multiplication and addition. Recognize area as additive and find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems. Decompose a rectangle into smaller rectangles to find the area of the original rectangle. Use place value understanding to round whole numbers to the nearest 10 or 100. Read, write and represent whole numbers up to 100,000. Representations may include numerals, expressions with operations, words, pictures, number lines, and manipulatives such as bundles of sticks and base 10 blocks. Use place value to describe whole numbers between 1000 and 100,000 in terms of ten thousands, thousands, hundreds, tens and ones. Round whole numbers to the nearest 10 or 100.
