Interactive Math Lesson - Flat Shapes

Students will identify two-dimensional shapes in this interactive math lesson geared toward second grade. As students work through this geometry activity, they will become familiar with circles, triangles, squares, rectangles, rhombuses, trapezoids, pentagons, hexagons, and octagons. Upon completion of this online math lesson, children will have gained confidence and proficiency in identifying flat shapes.

Here are some examples of the types of geometry problems your students can expect to solve in this online math game. "Drag the shapes into the chart." Students must sort the hexagons and the circles correctly. "How many sides does a rectangle have?" "How many corners does a rectangle have?" Students must fill in the blank with the correct answer. "Identify the shape." Students will choose from a rectangle, a square, and a rhombus.

Built-in features help students maximize their math practice sessions and master new skills. A "Hint" button is available for students when they get stuck on a question. When they click the button, they will be shown a written or pictorial clue that will help them solve the problem. When students answer a question incorrectly, a detailed explanation page will show them where they went wrong, helping them learn from mistakes. A progress-tracker in the upper-right corner of the practice screen displays how many questions have been answered out of the total number of questions in the activity. A score-tracker shows students how many points they have earned by answering math questions correctly. Plus, a read-aloud button allows students to hear the question read out loud to them in a clear voice - a wonderful option for ESL/ELL students and students who are auditory processors.
