Multiplication-Grouping Exploration!

For students of 2nd to 3rd grade.

Objective: Students will investigate objects that occur in specific numbers (2s, 3s, and 4s).

Materials: The book "2X2 Equals Boo", paper, pencils, chart paper, markers, a pair of earrings or socks

Procedures:
Hook: 
Start the lesson by holding up the earrings or socks and tell the students that there is something special about earrings and socks, and to see with a partner if they can figure out what it is (they both come in pairs).
Read the book "2X2 Equals Boo" to the students and discuss some of the objects in the story that come in pairs.

1. After reading the story, write on one piece of chart paper "2's", another piece of chart paper "3's" and a last piece of chart paper "4's." Tell the students that the class is going to investigate various objects that come in 2s, 3s, or 4s.

2.  Also, have students fold their paper into three equal sections (you may have to model this for the students), and have them put in one section "Things that come in 2s", in another section "Things that come in 3s", and in the last section "Things that come in 4s." You may already have an organizer done for the students with this on it if you like.

3.  Have the students give something that comes in a group of 2, 3, or 4 and record on each piece of chart paper. Some examples may include earrings (2), primary colors (3), and sides on a square (4). Allow the students to record these on their organizer as well.

4. Working with a partner (collaborative pairs), have the students come up with 4 more things that come in groups of 2, 3, or 4. 

Closure:
Have students share their findings from their organizer with the class and record on chart paper(s). 

This lesson may be extended to finding things in 5s, 6s, 7s, 8s, as high up as the teacher would like (12 would probably be the highest since students are starting to learn their multiplication facts up to 12.)
