## Interactive Math Lesson - Quadrilaterals

Help your students become familiar with quadrilaterals in this interactive geometry activity geared toward fifth grade. Children will practice identifying the properties of quadrilaterals, including parallelograms, rectangles, triangles, rhombuses, and more, by their sides and angles in this online math game. Upon completion of this math practice activity, your students will have gained confidence in their ability to identify quadrilaterals by their attributes.

Students will be challenged by a variety of question types in this online geometry lesson. One question may ask, "Which two quadrilaterals always have four right angles?" Students must choose the rectangle and the square. Students may be asked to "Drag the quadrilaterals with two pairs of parallel sides into the box." They must sort the quadrilaterals accordingly. Or students may be given a statement which they must identify as true or false, like this one: "A parallelogram always has four right angles."

Our interactive lessons are designed to help children expand their math skills with built-in learning tools. The "Hint" feature is available for students when they need a little extra help answering a math question. Students can click the hint button to view a detailed illustration which will help them visualize the geometry concept in question. When students answer a question incorrectly, a detailed explanation page appears to show them the correct answer with an easy-to-follow explanation. Students move through each practice session having learned from past mistakes.

Other helpful features in I Know It math practice activities help students make the most of their math practice sessions. A progress-tracker in the upper-right corner of the practice screen shows students how many questions they have answered out of the total number of questions in the lesson. A score-tracker lets students see how many questions they have answered correctly so far. A speaker icon in the upper-left corner of the practice screen indicates the read-aloud feature. Students can click the button and the question will be read out loud to them in a clear voice. This is a helpful resource for ESL/ELL students and students who are auditory processors.
