Big Ideas: Understand that numbers can be compared by plotting them on a number line. Numbers to the right on a number line have a greater value. This lesson builds on students’ work with number lines and comparing numbers. In this lesson students will be asked to look at a table that displays the distance paper airplanes flew. They will then be asked to compare the distances flown by plotting points on a number line and recording their comparisons with the and = symbols. The mathematical concepts in this lesson further develop students’ use of tools to model mathematics. Vocabulary: compare, equal, digit, value place, more than, less than, greater than, numeral, number, word form Special Materials: Task Document Number Lines Response Boards
