Get your fourth grade class geared up to practice operations with fractions with a fun digital math game! Students will put their addition and subtraction skills to the test in this interactive math lesson featuring mixed numbers with like denominators. Here are the learning objectives for this fourth grade mixed fractions activity:

- Add mixed numbers with like denominators
- Subtract mixed numbers with like denominators
- Solve mixed number addition word problems
- Solve horizontal mixed number addition and subtraction problems
- Solve vertical mixed number addition and subtraction problems

Students will use their knowledge of addition and subtraction to solve math problems involving mixed fractions and simplify if possible.

Here are a few math lesson components that are designed to help children maximize each math practice session:

- Digital math progress tracker – This tool allows students to see how many questions they have answered so far out of the total number of questions in the math lesson. Students can find the math progress tracker in the upper-right corner of their practice screen.
- Online math score tracker – This feature gives students a peek into how many points they have earned for correct answers so far in the math lesson. Students can find the math score tracker directly beneath the progress tool on their practice screen.
- Read-aloud feature – This handy option is indicated by a speaker icon in the upper-left corner of the practice screen. Students can click the button to have the question read out loud to them in a clear voice. This tool is an excellent resource for ESL/ELL students and children who are auditory processors.
- Hint button – A helpful hint is available to students when they get stuck on a mixed fractions addition or subtraction problem. Students can click the "Hint" button to view a written or pictorial clue, which may appear as a prompt for the first couple of steps in the math problem. For example: "Step 1: Add the fractional parts. Step 2: Add the whole numbers. Simplify if possible." Students can use this information to solve the problem without receiving an easy solution.
- Explanation page – When students get a n answer wrong, a detailed explanation page will pop up on the screen to show them the correct answer with an easy-to-follow explanation. Students can learn from mistakes and improve their accuracy as they move through their digital mixed numbers practice.
