Put your students' graphing and data skills to the test with a fun, interactive math game from "I Know It." In this online math lesson, students will practice finding the mean, or average, for a set of data. Here are some of the math skills your fourth grade students will master in their math practice session:

- Find the mean, or average, of the set of numbers.
- Find the mean, or average, of the numbers in a table.
- Find the mean, or average, of the numbers in a graph.
- Find the mean, or average, of the numbers in a word problem.

Children will answer multiple-choice questions and fill-in-the-blank questions in this digital math game.

Here are a few handy, built-in tools that are available to your students as they practice finding mean, or average, in this fourth-grade math lesson:

- Hint button – Students can click on the hint button when they need a little extra help solving a math problem. The hint consists of a written or pictorial clue that will point them in the right direction without giving away the answer.
- Explanation page – Students will view a detailed explanation page on their practice screen when they answer a question incorrectly. The explanation page displays the right answer accompanied by an easy-to-follow explanation, helping students learn from their mistakes and improve their accuracy as they progress through the math activity.
- Progress-tracker – Students can check out the progress-tracker to see how many questions they have left to answer out of the total number of questions in the math activity.
- Score-tracker – Students can view the score-tracker if they want to see how many points they have earned for answering questions correctly.
- Read-aloud button – Students can click the speaker icon to hear the question read out loud to them in a clear voice. This is an excellent resource for ESL/ELL students and children who are auditory processors.

The I Know It team designed all of these built-in features to help your students develop their confidence and proficiency in basic math skills, including finding the mean, or average, of a data set.
