Addition and Subtraction Egg Hunt

1. Begin the lesson with a number talk. Write any number on the smart board (a double digit number for first grade). The purpose of the number talk is to create a classroom discussion that will get students engaged in the mathematics of the lesson. This will give the teacher an understanding of his/her students’ number sense and foundational skills they obtain and need for this lesson. 
2. Next, the students will break into groups, and then the teacher will distribute the materials (pencil, scratch paper, index cards, clipboard).
4. Then the teacher will give each group a bin of broken plastic eggs. The eggs will be broken up because the top half of the egg will have an addition or subtraction problem written in permanent marker. The bottom half of the egg will have the answer to the problem written in permanent marker. 
5. The students will have 20 minutes to collaborate with their group members and match up the pieces of the plastic eggs. The goal is for each group to match as many as they can.
6. Students will write the problems and the sums and differences they find on index cards.
7. At the end of the lesson, the students will have the chance to teach the class how to solve their problems and to have a student-led discussion with their peers. They can use the index cards while teaching, and at the end of the lesson the teacher can use these index cards as a math flash card game for the class. 

Differentiation: Consider heterogeneous / homogeneous groupings. Pull small groups for remediation when necessary. Assist students in recording their thinking and model a sample. If larger numbers are confusing the student, begin with smaller values and work their way up.

Extension: 

1. Add golden eggs for enrichment (three digit addition and subtraction with or without regrouping)
2. Have students hunt for eggs around the classroom individually 
3. Create a requirement for the number of eggs the students need to match up.
