Mrs. N's Math Class: Unit 4 Time, Multiplication and Division
MCPS Curriculum Information for Grade 3 and Grade 4 Math Classes:
Grade 3 What your child will learn Students in Grade 3 use mathematics to model real world situations.
In Unit 1, students organize, interpret, describe, and compare information using tables, pictographs, bar graphs, and patterns. Students use flexible methods of computation that involve grouping numbers in a variety of ways. Students demonstrate understanding that the base 10 number system is based on groups of ten. In Unit 2, students study standard units of measurement and their relationship to each other. Students estimate and determine area and perimeter of shapes and analyze the similarities and differences between them. In Unit 3, students explore and model multiplication and division concepts. Students explain and apply the concept of inverse operation as it relates to multiplication and division. Students will demonstrate mastery of multiplication facts for 0, 1, 2, 5, and 10. The use of estimation techniques to determine solutions are also included in this unit. In Unit 4, students connect their earlier work with two-dimensional figures to three-dimensional figures. Students investigate angles, symmetry, and congruency of geometric figures and real world objects. In Unit 5, students model and compare fractions using numerals, regions, sets, and number lines. Students investigate and solve money problems through one hundred dollars. Students continue their multiplication and division strategies and represent expressions, equations, and inequalities. In addition, students explore the concept of probability. In Unit 6, students continue their study of appropriate measurement tools to solve problems. Students use estimation and measurement strategies to help determine length, weight, time, and capacity. In addition, students investigate ordered pairs on a coordinate plane
Grade 4 What your child will learn Students in Grade 4 use mathematics to model real world situations. In Unit 1, students organize and display data in a variety of ways, including line plots, line graphs, and circle graphs. They analyze the appropriateness and inappropriateness of various data displays. Students determine the mean, median, mode, and range of data. Students explore, model, and identify place value in large numbers. In addition, student’s identify/classify/draw angles and describe how points, lines segments, rays, and angles are related. In Unit 2, students solve for an unknown, generalize a pattern by stating a rule, and complete a function table using a given rule. Students explore the commutative and associative properties. Students continue to develop proficiency with basic facts. Students find multiples and factors of numbers in order to help with mastery of multiplication and division fact families. In Unit 3, students study the relationship between fractions and decimals. Students recognize, name, compare, and order fractions and decimals. Students practice adding/subtracting fractions with like denominators and decimal fractions. Students use models and pictures to multiply a fraction by a whole number. In addition, students explore probability concepts. In Unit 4, students continue to develop proficiency with multiplication and division as it applies to two-or-three-digit factors. Students practice estimation and reasonableness of answers. Students examine equivalent periods of time and determine elapsed time. In Unit 5, students explore specific movements of objects to identify and describe transformations. Students estimate, measure, determine, and use formulas as it relates to perimeter, area, and volume to solve problems. Students are introduced to positive and negative numbers in concrete situations.
