In this Grade 4 Pengi Math lesson, students learn to construct dot plots and line plots to display measurement data in fractions (1/2, 1/4, and 1/8) and identify key statistical features including minimum, maximum, mode, and range. Students also practice calculating total values from line plots using frequency multiplication and apply their skills to solve addition and subtraction word problems using data from line plots.
Section 1
Creating a Line Plot with Fractional Data
To create a line plot from a data set, first draw a horizontal number line that spans the range of the data (from minimum to maximum value).
Determine an appropriate fractional scale (e.g., halves, fourths, eighths) by finding a common denominator for the data points.
Title the plot, label the number line, and then plot each data point by placing an 'X' above its corresponding value on the number line.
Section 2
Identifying Key Features of a Line Plot
Section 3
Solving Word Problems Using a Line Plot
To solve a word problem using a line plot, translate keywords from the problem into mathematical operations performed on the data values.
