Our math topics for 3rd grade learners are designed to follow closely the Common Core standards for math for 3rd grade pupils.
In Grade 3 of the Common Core State Standards (CCSS) for Mathematics, the focus in addition builds upon the foundational skills developed in previous grades. The addition standards in Grade 3 aim to develop students' fluency in addition facts, their understanding of place value, and their ability to solve addition problems in various contexts. Here are some key aspects of addition in Grade 3:
Addition and Subtraction within 1,000: Students are expected to fluently add and subtract within 1,000 using various strategies. They should be able to mentally add and subtract numbers, use strategies based on place value (e.g., adding tens or hundreds), and apply standard algorithms for addition and subtraction.
Properties of Addition: Students should understand the properties of addition, such as the commutative property (changing the order of addends does not change the sum) and the associative property (changing the grouping of addends does not change the sum). They should be able to apply these properties to solve addition problems.
Estimation: Students should develop the ability to estimate the sum of two or more numbers and determine whether an answer is reasonable. Estimation helps students check the reasonableness of their solutions and develop number sense.
Word Problems: Students should be able to solve addition word problems, including those involving two or three-digit numbers. They should understand the problem, identify the relevant information, and choose an appropriate addition strategy to solve it.
Fluency in Addition Facts: Students should demonstrate fluency in adding within 20 and develop efficient strategies to derive unknown sums from known facts. They should also be able to use addition to solve related subtraction facts.
Mental Math Strategies: Students should develop mental math strategies for addition, such as using doubles (e.g., 7 + 7 = 14, so 7 + 8 = 15) or making tens (e.g., 6 + 8 = 6 + 4 + 4 = 14). These strategies help students build number sense and flexibility in mental calculations.
By the end of Grade 3, students should have a solid foundation in addition, including fluency in addition facts, understanding of place value, and the ability to apply addition strategies to solve problems. These skills prepare them for more complex addition concepts and applications in higher grades.

A topic is selected at the beginning of a session at Free Math Games and will be remembered when you move between games or activities. The math for the topic is carefully constructed to match the elementary math level commonly taught in US schools. This means that you as an elementary pupil should see similar math problems to those you are seeing at school (if you are at school) for any particular subject. Please let us know if that is not the case.
See the help box below for instructions on choosing a topic here at Free Math Games.
UXO * Duck shoot * The frog flies * Pong * Cat and mouse * The beetle and the bee
Rock fall * Four in a row * Sow grow * Choose or lose * Mix and match
Click on the "1. Start" button in the top navigation bar - that brings you to this elementary level topic selection page. On the topic selection page you will see that the topics are divided up:
Since you are currently within the elementary section of Free Math Games you will see the elementary topics. The elementary grades will have loaded. Choose your grade. The broad categories available will load. Click on a category to see the available sub-categories and topics.
For example, if you choose fifth grade, then the category: "Fractions" you will be offered a choice of fraction sub-categories and topics suitable for Grade 5. Click on each sub-category to view the available topics.
When you click on the name of a topic, the topic will load into the lesson page (once a topic has loaded it will be available for all activities and will not have to be downloaded again) and the lesson start page will be displayed. You can choose to do the lesson or jump immediately to the games using that topic.
