Big Ideas: A digit's value changes depending on its location in a number. We can use symbols to compare numbers according to their values. (< means less than, > means greater than, = means equal to) This lesson builds on students' work with comparing numbers using knowledge of place value. In this lesson, students will be asked to sort cards to make comparisons between numbers written in different forms. They will then be asked to explain their reasoning for each comparison. The mathematical concepts taught in this lesson build toward a well-developed understanding of the base 10 number structure. This will allow students to manipulate and make sense of numbers that are more complex. Vocabulary: compare, equal, expanded form, digit, value, place, more than, less than, greater than, less than, numeral, number, word form, number parts Special Materials: Sorting Cards
