Students examine finding the sum of an infinite series as the limit of partial sums. Through hands-on activities, students create their own sequence by finding the area of a square and then cutting it in half-sized pieces. They write out the series of areas to discover a pattern. Assuming the pattern were indefinite, students find the sum. Full Review »

Students compare and contrast an arithmetic series and a geometric series through the construction of arithmetic and geometric means. They observe the computation method and receive step by step instruction of the geometric mean. Students may compose their own series and give it a visual representation. Full Review »

Students practice how to find the sum of the first n terms of the related series. Students use formulas to find the differences of consecutive terms. They create a scatter plot of each sequence and discover that sequences with common differences have scatter plots that form form a straight line. Full Review »
