A line chart, also known as a line graph, is a type of chart that displays information as a series of data points connected by straight line segments. It is commonly used to show how data changes over time or to display trends.
Linecharts are valuable tools for visually representing and analyzing data trends. By understanding their components and interpretation, you can effectively communicate and extract insights from line chart data.
Number and Operations: In grade 4, students used equivalent fractions to determine the decimal representations of fractions that they could represent with terminating decimals. Students now use division to express any fraction as a decimal, including fractions that they must represent with infinite decimals. They find this method useful when working with proportions, especially those involving percents. Students connect their work with dividing fractions to solving equations of the form ax = b, where a and b are fractions. Students continue to develop their understanding of multiplication and division and the structure of numbers by determining if a counting number greater than 1 is a prime, and if it is not, by factoring it into a product of primes.
