### Overview

In Math Grade 3, students will learn to multiply and divide within 100 to solve word problems. The course provides the opportunity for students to develop an understanding of fractions, arrays, and area. Describing and analyzing 2-D shapes is another focus of the course. Other engaging activities include learning about data, time, and measurement.

Please view the Elementary Parents’ Survival Guide: The First Four Weeks of Online Learning for guidance on helping your student in the transition to online learning.

### Course Requirements

To achieve success, students are expected to submit work in each course weekly. Students can learn at their own pace; however, “any pace” still means that students must make progress in the course every week. To measure learning, students complete self-checks, practice lessons, multiple choice questions, projects, discussion-based assessments, and discussions. Students and families are expected to maintain regular contact with teachers because, when teachers, students, and parents work together, students are successful.

### Competencies

Students will demonstrate an understanding of addition facts by adding two- and three-digit numbers, identifying even and odd numbers, identifying arithmetic patterns, and rounding numbers to the nearest ten or hundred.
• Fluently Add and Subtract Within 1,000
Students will demonstrate an understanding of adding and subtracting within 1,000 by decomposing numbers using place value, using various techniques to add three or more two- or three-digit numbers up to 1,000, and using various techniques to subtract two- and three-digit numbers with the whole less than 1,000.
• Represent and Interpret Data
Students will demonstrate an understanding of representing and interpreting data by reading pictographs or bar graphs to answer questions, drawing scaled pictographs and bar graphs, and solving one- and two-step word problems using information represented in a bar graph or a pictograph.
• Understanding Multiplication and Division
Students will demonstrate an understanding of multiplication and division by solving multiplication equations using addition, number lines, and the commutative property; solving multiplication word problems with products less than or equal to 100; and solving division word problems with wholes less than or equal to 100.
• Multiplication Facts and Patterns
Students will demonstrate an understanding of facts and patterns by solving multiplication equations involving the factors 0, 1, 2, 5, 9, and 10, and solving multiplication word problems involving the factors 0, 1, 2, 5, 9, and 10.
• Multiplication Facts for 3, 4, 6, 7, and 8
Students will demonstrate an understanding of multiplication facts for 3, 4, 6, 7, and 8 by solving multiplication equations involving the factors of 3, 4, 6, 7, and 8, using the associative and distributive property of multiplication to solve equations, and by solving multiplication equations that have three numbers.
• Division Facts
Students will demonstrate an understanding of division facts by identifying and explaining patterns in multiplication, showing how multiplication and division are related, using multiplication to solve division equations with 2-9, dividing any number by 1, and dividing 0 by any number.
• Multiplication and Division Fluency
Students will demonstrate an understanding of multiplication and division fluency by finding and explaining patterns in multiplication and the multiplication table, fluently solving multiplication equations with products less than or equal to 100, and solving one- and two-step word problems involving multiplication and division within 100.
• Multiplying by Multiples of Ten
Students will demonstrate an understanding of multiplying by multiples of ten by using an open number line to multiply by multiples of 10 and solving multiplication equations by using the associative and distributive properties.
• Connect Area to Multiplication and Addition
Students will demonstrate an understanding of the connection between area and multiplication and addition by using addition and multiplication to find the areas of squares and rectangles, using the distributive property to find the total areas of partitioned rectangles, and decomposing irregular shapes into rectangles to find their area.
• Time, Capacity, and Mass
Students will demonstrate an understanding of time, capacity, and mass by writing time to the nearest minute and identifying how much time has passed, estimating and measuring the liquid volume of a container, and estimating and measuring the mass of any object.
• Understanding Fractions as Numbers
Students will demonstrate an understanding of fractions as numbers by reading and writing fractions, identifying how fractions relate to the whole, representing fractions of a whole and greater than one on a number line, partitioning shapes into equal parts and naming them using one-half, one-third, one-fourth, one-sixth, and one-eighth, and measuring lengths to the nearest whole, half, and quarter inch.
• Fraction Equivalence and Comparison
Students will demonstrate an understanding of fraction equivalence and comparison by recognizing and generating simple equivalent fractions, comparing fractions with the same numerator using the >, =, or < symbols, comparing fractions with the same denominator using the >, =, or < symbols, expressing whole numbers as fractions, and recognizing fractions that are equivalent to whole numbers.
