## Online Math Lesson - Symmetry

Get ready for some serious symmetry practice with this fun, interactive math lesson from iKnowIt.com! Your second grade students will put their basic geometry skills to the test as they decide whether the dotted line shown is a line of symmetry. Questions in this digital symmetry game are presented in multiple-choice format and drag-and-drop format. Here are a few of the types of questions students may be expected to answer in the math activity:

• "Drag to sort the shapes into the T-chart." Students will sort the shapes based on whether each shape has a line of symmetry not.
• "Which line of symmetry is correct?"
• "Is the dotted line a line of symmetry?"

As children work through their online math lesson, they will have access to handy features that will help them make the most out of their math practice session:

• Hint Button â€“ Students can click on the "Hint" button if they need a little extra help solving a math problem. The hint displays a written or pictorial clue that will point students in the right direction without giving away the answer.
• Explanation Page â€“ A detailed explanation page pops up on the practice screen when students submit an incorrect answer. The explanation page displays the correct answer accompanied by an easy-to-understand explanation.
• Progress-Tracker â€“ Students can check out the progress-tracker in the upper-right corner of the practice screen to keep track of how many questions they have answered so far out of the total number of questions in the math activity
• Score-Tracker â€“ Students can also take a look at the score-tracker to view how many points they have earned for submitting correct solutions to the math problems.
• Read-Aloud Feature â€“ The speaker icon in the upper-left corner of the practice screen indicates the program's read-aloud feature. Students can click the button to hear the question read out loud to them in a clear voice. This is a great resource for ESL/ELL students and children who are auditory processors.

These tools are designed to help your students achieve greater understanding in each math practice session and grow in confidence and proficiency.
