Our math topics for 4th grade learners are designed to follow closely the Common Core standards for math for 4th grade pupils.
Here's an overview of the key topics covered in the subtraction syllabus for 4th grade:
Review of basic subtraction: Students revisit and reinforce their understanding of basic subtraction facts, including single-digit subtraction problems (e.g., 7 - 3 = 4).
Mental math strategies: Pupils develop mental math strategies to perform subtraction more efficiently. These strategies include using place value concepts (e.g., subtracting tens or hundreds first), breaking down numbers into easier parts, or using known facts to solve related problems.
Multi-digit subtraction: Students are introduced to subtraction problems with two or more digits. They learn the concept of borrowing or regrouping when the minuend (the number being subtracted from) is smaller than the subtrahend (the number being subtracted). For example, in the problem 752 - 398, they learn to regroup or borrow from the tens or hundreds place to perform the subtraction.
Estimation: Students learn to estimate the answer to subtraction problems. They develop an understanding of how to round numbers and make quick approximations to assess whether the answer they obtain is reasonable.
Problem-solving: The syllabus incorporates problem-solving activities to apply subtraction skills to real-world situations. Students practice identifying relevant information, choosing appropriate subtraction strategies, and solving word problems involving subtraction.
Subtraction with decimals and fractions: Depending on the syllabus, students may begin to explore subtraction involving decimals and fractions. They learn to align decimal points and subtract place by place. With fractions, they understand the need to find a common denominator before performing the subtraction operation.
Timed drills and fact fluency: To enhance computational speed and accuracy, students often engage in timed drills or activities to improve their subtraction fact fluency. This helps develop rapid recall of subtraction facts, making mental calculations easier and more efficient.
Throughout the syllabus, hands-on activities, visual representations (such as number lines or base-10 blocks), and interactive exercises may be used to support conceptual understanding and reinforce computational skills. Additionally, technology-based tools and educational games (!) can provide supplementary practice and reinforcement of subtraction concepts.

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.
