Having a Ball with Number Sense

1.    The teacher will begin this lesson by engaging students with a number talk. A number talk will get students engaged, thinking on deeper levels, and will give them a sense of ownership in the lesson. The teacher will begin the number talk by choosing a teen number (10-19). The teacher will scaffold students to create the number using multiple methods (base ten blocks, drawing pictures, tens frames, number sentences, etc.)
2.    Next, the teacher will call a student to the front of the room to “be the teacher”.
3.    Then that student will choose a teen number that he/she would like to represent and write it on the board. 
4.    After that, the student will use beach balls to fill in the tens frames made with painter’s tape on the ground. Students who are not “the teacher” will count with the student and will put a thumbs up if they agree and a thumbs down if they do not agree.  
5.    The teacher will repeat the process until each student has a turn. 
6.    The teacher can choose partners instead of having students going individually to save time and keep them actively engaged. 
7.    Once students have had enough time to have a turn with the giant tens frame, they can move to centers where they will be assessed on their knowledge in a variety of ways. 

Center 1: For the students who still need help counting and writing from 0-20.

Overview: Students will practice writing numbers 0-20 using iPads. Have students connected to the see-saw application on their iPad, where they will begin a new project. Students can write and share their work with classmates and parents. 

Directions: 
-The student will roll a dice or two di and count how many dots are on the upright faces they rolled. Students will then say and write the number on seesaw by adding a drawing and posting it for their classmates, teacher,  and families to see. 

Materials: dice and iPad 

Center 2: Representing numbers 0-20 using number sentences. 

Overview: Students will practice writing number sentences using dry erase markers and seesaw. The students will have a chance to write on their desks, yes, write on their desks using dry erase markers.

Directions: Students will partner with someone in their group. Their partner will give them a teen number, and together they will write a number sentence on their desk using the dry erase markers. They will then take a photo on seesaw and post it. 

Materials: Dry erase markers, desks, and ipads 

Center 3 (with teacher): Representing numbers 0-20 using tens frames

Overview: students will represent numbers 0-20 by putting thumbprints into tens frames. 

Directions: The teacher will give students a teen number, and then will assist them in putting thumbprints into tens frames. 

Materials: finger paint, paper 

Center 4:  Representing numbers 0-20 using objects

Overview: Students will use tens blocks to represent teen numbers. 

Directions: Students will roll di, represent number using tens blocks, then post a video to seesaw.

Materials: tens blocks, ipads

Extension: Give students multiple tens frames to increase the numeric values over 19.

Differentiation: Pull small groups for remediation as necessary. Focus on filling one tens frame with red and yellow chips. Have students focus on negative space to work with the part-part-whole concept. Move to increase values into the "teens".
