Circle Art<\/strong><\/p>\n<p>Teachers at school can conduct various activities through which the concepts of circle can be explained creatively. Students can be taught the concepts of diameter and circumference through activities. The symbol and importance of Pi can be explained to students.<\/p>\n<p><strong>2. Bake a PiE<\/strong><\/p>\n<p>Families can involve in a fun and learning activity by baking cakes in the shape of circle or pie. At the same time the concepts of circle can be taught to the smaller kids at home.<\/p>\n<p><b>3. Memorize Pi Contest<\/b><\/p>\n<p>A contest can be conducted at institutions where in each one can try memorizing the decimal numbers of pie. It will be fun and learning at the same time.<\/p>\n<p><strong>4. Organize a pizza\u00a0 party for kids<\/strong><\/p>\n<p>Elders can organize a pizza party for kids . As pizza takes the shape of the circle, when each part is cut into triangles, the concept of fractions and\u00a0 geometry can be explained to students<\/p>\n<p><strong>5. Teach Math through fun and learning activities<\/strong><\/p>\n<p>We tend to see that majority of students doesn&#8217;t like math most of the time cause of how hard it gets later on. But if math is taught through activities and practical learning methods then students may be able to grasp things better. So teachers and elders can try to keep math as engaging and creative as possible<\/p>\n<p><strong>6. Organize Circle hunt activity at Office or school<\/strong><\/p>\n<p>A quick ice breaking activity can be conducted to de-stress the employees when at work by checking for circle shape items around the cabin and calculating the ratio of circumference of the circle to its diameter<\/p>\n<p><strong>7. Formation of Pi Chain<\/strong><\/p>\n<p>Students at school can be engaged in an activity of constructing a pie chain using paper. each circle cut outs can represent one digit or decimal number by representing it in a different color. This will also help in improving the color recognition skills and fine motor skills of the kindergarten students.<\/p>\n<p><strong>8. Conduct Quiz<\/strong><\/p>\n<p>A quiz on mathematics can be conducted online thus encouraging students to learn more about the numbers and values and making it interesting in every way possible<\/p>\n<p><strong>9. Organize a walk-a-thon of 3.14 miles<\/strong><\/p>\n<p>A walk-a-thon can be organised in a community for 3.14 miles thus representing the value of pi. health and fitness can also be highlighted during the event. If fund is raised during the process then it can be donated as charity for the education of students<\/p>\n<p><b>10.
