Comparing Double Digit Numbers

Introduction:
1.    During the introduction of this lesson, the teacher will begin by engaging the students by doing a class count-around. The count around should begin with the number 15 and end with the number 95 counting by 5’s.

2.    Next, the teacher will explain what greater than, less than, and equal to means. 
3.    The teacher will have all of their students on one side of the room except for two of the students who will stand on the other side of the room. The teacher will say “Which side of the room has more students?” When the students say that the side with more students, the teacher will say, “That side of the room has a greater amount of students than the other side of the room. Greater than means that there are more of something or there is a larger quantity.” The teacher also will write GREATER THAN on the board for students who need a word bank or visualization.
4.    Next, the teacher will say, “Which side of the room has less than the other sire/fewer students?” When the students identify the side of the room with the least amount of students the teacher will say, “This side of the room is less than the other side of the room. Less than means that the amount is smaller or fewer than the other number.” The teacher will write LESS THAN on the board.
5.    Then, the teacher will have one-Half of their students go to one side of the room and the other half goes to the other side of the room. The teacher will then ask their students which side has more students. When the students respond the teacher will say, “There is the same number of students on each side of the room. That means that this side is equal to this side. Equal means that there is the same amount of something.” 
6.    Activity: Next the teacher will split students into small groups and give them each two printed two-digit numbers and the words greater than, less than, and equal to. The students will compare the two two-digit numbers and place a group of words in between them, take a picture, and upload to the see-saw app.
Example: 65 greater than 43. 
7.    The teacher will close lesson by writing all of the group's problems on the board and have all students write number sentences on their personal dry-erase boards. 
Assessment: Teacher will take anecdotal notes while looking at students’ individual whiteboards and looking at uploaded photos on the see-saw app. 

See-Saw app is free for teachers to download. This application allows students to upload photos, videos, and activities in a way where families and teachers can view through smartphone or iPad. These photos can be liked by parents, teachers, and other classmates 

Differentiation: Pull for small group remediation as necessary. Begin by comparing tens (or, if necessary, even ones). Work up to any double digit numbers, emphasizing to begin comparisons by looking at the greatest place value.

Extension: Give 3-5 double digit numbers (or triple digit numbers) for students to compare and place in order from least to greatest.
