Third Grade Math Curriculum?

A third grade lesson plan relies on many learning tools – 3rd grade math worksheets, 3rd grade math games, and lots of 3rd grade math activities and word problems to ensure relevancy.

The major math strands are number sense and operations, algebra, geometry and spatial sense, measurement, and data analysis and probability.

Third grade math students build on what they learned in kindergarten, first grade and second grade math, which led them to the number 1000. In third grade math they work with numbers through the hundred-thousands or more. They learn about decimals in the context of money and get experience with fractions up to 100. Third grade math opens them up to a greater understanding of measurement techniques, geometry and algebraic thinking. It will be a challenging year as they are presented with many new and complex concepts.

This guide to a third grade math curriculum is a reference tool for Time4Learning parents. Time4Learning is an online learning system for homeschool education, enrichment, tutoring, or for sharpening summer skills. We provide 3rd grade math worksheets and 3rd grade math games in a total curriculum. Each unit has multimedia lessons, interactive exercises, printable worksheets for reinforcement, and assessments.

Third Grade Math Curriculum and Standards – Lessons, Activities, Worksheets – Number Sense and Operations

Third grade math students compare and order numbers through one hundred thousand. They learn fractions including thirds, fourths, fifths, sixths and eighths. Using money they’ll learn about decimal notation.

Third grade math students learn about extended forms of numbers and know the value of any given digit in whole numbers to thousands. They learn that the value of each place is ten times that of the place to its right. They are asked to compare the decimal number system with Roman numerals.

Third grade math students work with whole numbers of three digits or more. They will understand and explain the inverse relationship of addition and subtraction and write related fact families. They demonstrate an understanding of multiplication by skip counting, modeling with objects or drawings, and using doubles.

They learn about the commutative and distributive properties of multiplication, noting patterns in the facts tables such as the regularity of fives and nines. They are asked to explain the inverse relationship between multiplication and division and to write related fact families. Children in third grade math learn about division including an understanding of remainders.

Third grade math students choose estimation strategies for real-world problem situations, estimate quantities of objects to 250 or more, and determine reasonable estimates of quantities. They predict relative sizes of solutions in addition, subtraction, multiplication, and division and are able to explain the reasonableness of their answers.

I LOVE Time4Learning! It holds the attention of my kids, plus I can keep track of their learning without hovering over their shoulders.

I am really pleased with Time4Learning. It has made a world of difference in my son’s academic performance in school!

Third Grade Math Curriculum and Standards – Lessons, Activities, Worksheets – Measurement

Third grade math students learn new measurement concepts and use both oral and written language to explain them. They’ll be using a variety of objects to measure length, weight, capacity, area, perimeter and volume. They learn about money to the nearest $1 or $10 using a combination of coin and currency.

The third grade math students learn more about how to measure time using clocks and calendars. They’ll be asked to differentiate between A.M. and P.M. and to use schedules, calendars and elapsed time in hour intervals to solve real-world problems. They are expected to know about time in half-hour, fifteen-minute, five-minute and one-minute intervals.

In third grade, math students learn more about temperature scales using both Fahrenheit and Celsius thermometers. They are taught to know about temperature to the nearest five-degree interval.

New concepts for third grade math include right angles, perimeter, area and volume. They will calculate and compare measurable characteristics, use both customary and metric units to measure length, weight and capacity, know all the appropriate units of measure, and be able to solve real-world problems using these concepts. They will measure weight to the nearest pound or kilogram, and length to the nearest inch or centimeter. Third grade math students learn to estimate the area and perimeter of squares and rectangles using graph paper, geoboard, or other tools. They will also estimate the volume of a rectangular prism.

Learning the Math Facts, Where do they fit in building a math foundation?

*Math Standards are defined by each state. Time4Learning bases its use of standards on the national bodies that recommend curriculum and standards and the interpretations of it by a sampling of states notably Florida, Texas, and California. Time4Learning’s third grade math help provides an interactive 3rd grade math help, lesson plans useful for helping most third grade math students with their math problems around the country and world. One Feature of Time4Learning is access to lesson plans and help at both the grade above and below that a student is working at so a student who enrolls in the third grade math program but who finds, for example, the fractions too difficult can get math help by clicking down to the second grade math fractions level
