# Third Grade Math Activities & Curriculum Standards

Third grade math curriculum should rely on many learning tools – lessons with interactive activities, printable worksheets, reinforcement exercises, assessments and math strands.

The major math strands for a third grade curriculum are number theory and systems, algebraic thinking, geometrical figures and objects, measurement of length, weight, capacity, time, and temperature, and data analysis and probability. While these math strands might surprise you, they cover the basics of what a third grader should learn in math.

### Third Grade Math – What are the Standards and Curriculum?

Time4Learning teaches a comprehensive third grade math curriculum using fun activities to build a solid math foundation in the following five major math strands:

### Number Theory and Operations

In third grade math, students will be expected to:

• Compare and order numbers
• Convert numbers from standard form to expanded form
• Round numbers up to the ten-thousands to the nearest tenth and hundredth

Basic arithmetic is an important skill for third grade math. The children will learn to :

• Add and subtract 2 and 3 digit numbers
• Introduction to multiplication and division
• Multiplying and dividing 2-digits by 1-digits

• Count collection of coins and bills up to \$50
• Solving word problems that involve coins and bills
• Solve problems involving unit pricing of items

• Relate and write fractions and decimals
• Compare and order fractions and decimals

### Algebraic Thinking

Children in third grade math will represent, determine, and solve numeric expressions. They will:

• Represent and evaluate written relationships as numeric expressions
• Determine the unknown whole number in a division or multiplication equation relating three whole numbers
• Solve for an unknown quantity in an equation
• Understand properties of multiplication and division and apply properties as strategies to multiply/divide

### Geometry and Spatial Sense

• Find the horizontal or vertical distance between two points on a coordinate grid
• Plot a point on a coordinate grid given an ordered pair and write the ordered pair of a point shown on a coordinate grid
• Given a plane figure, identify the congruent shape and create a congruent shape using other plane figures
• Identify and apply a slide, flip, or turn to a plane figure and predict the result

### Measurement

During third grade math, children will show a basic understanding of measuring lengths, weights, capacity and time by selecting appropriate units to use for measurement. Student will also learn about both the metric and customary system by:

• Defining, telling, and showing time to the hour, half hour and quarter hour
• Interpreting time schedules using minutes, hours, days, and weeks
• Defining units of length, capacity, weight and temperature

*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.

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!

### Data Analysis and Probability

Third grade math students will be able to make predictions about events or situations. They will also:

• Display and interpret data using pictographs, bar graphs, tables and frequency tables
• Determine the certainty, likelihood, and fairness of events and the outcomes
• Solve two-step word problems using operations
• Students will apply mathematics to real-world problems using various mathematical models and tools.

### Third Grade Math Curriculum and Standards Summary

Third grade math lessons and activities that cover just one or two of these five strands are narrow and lead to a weak understanding of math.

But with Time4Learning’s comprehensive math program, children are placed in the sequence based on their current skills. Math becomes fun! Parents can participate and watch how new concepts are introduced progressively and mastered through practice. We also offer Time4MathFacts for third graders, which allows students to strengthen the fundamental math skills needed in future schooling. Help your child excel in math and start learning today.
