Here are the types of questions students can expect to encounter in this online math lesson:

* Solve a word problem containing fractions with unlike denominators.

* Solve addition problems with fractions in a vertical format.

* Solve fractional addition problems in a horizontal format. Use fraction strips to visualize the math problem.

## Math Practice in the Form of a Game

Elementary-aged students enjoy using the math lessons on iKnowit.com because each lesson feels like an exciting math game. The interactive math practice sessions are presented in a dynamic, kid-friendly format. Kids find our math games fun and entertaining.

Every time a student answers a question correctly, a cute animated character sends positive feedback by doing a funny dance clever trick. When a student answers a question incorrectly, the explanation page pops up with an easy-to-read graphic that breaks down the steps of the problem so the student can learn from his or her mistake.

If a student finds that he or she needs a push in the right direction, there's the "Hint" button in the lower left hand corner of the screen to refer to, at the teacher or parents' will. When the student clicks the "Hint" icon, he or she will be given a clue to help solve the math problem. Teachers or parents can decide how many hints per lesson a student should get.

iKnowit.com members who have an account with us will have unlimited access to all the helpful administrative features on iKnowit.com. Teachers can set up a class roster, add students to it, assign lessons to individual students, and keep track of their students' scores.

Each time a student logs into iKnowit.com, you will be able to track their progress and observe which problems are more difficult for that student. The student login page is "kid-friendly." Students will easily find the "Assignments from the Teacher" tab at the top of the page. They will also be shown a variety of suggested math topics to explore.

Students will not be able to see the grade level of the assignments they're given by the teacher, so educators can assign at a higher or lower grade level as needed.

Other administrative features include the ability to turn on and off the animated characters and the hint mode. Teachers can also choose whether they'd like students to use the read-aloud audio option.
