📍 Line Plots & Tally Marks: Organizing Frequencies on Number Lines ✏️

Gathering and organizing data can be fast, fun, and easy when we use tally marks and line plots! In this engaging lesson, second graders learn how tally marks help us count votes quickly one by one. Each tally mark is a neat vertical stroke, and when we reach five, we draw a diagonal slash across the four lines to create a bundle of five! Bundles make counting large amounts effortless through skip-counting by fives. Next, we transfer this data onto a number line to create a line plot. By placing an 'X' mark above each number on the line, we record how many times that score occurred. Guided by the key, which explains what each 'X' represents, students easily identify the most frequent value, compare frequencies, and analyze survey results with sharp mathematical precision.
