## Chapter 8

### Part 1: Home and School Investigation

Send the Letter to Family (PDF file) home with each child. Once all of the children have brought in their pictures, have them put the pictures on their desk, placing the picture with the greater number above the picture with the lesser number. If the numbers are the same, the child can put the pictures side-by-side. You can quickly check the children's work by walking around the room. A good time to do this activity is after Lesson 4 on more and fewer.

### Part 2: Be an Investigator

A good time to do this investigation is after Lesson 1 on names for 1-12.

#### Materials

- 12 counters for each group of two students

#### Introducing the Investigation

Introduce the investigation by showing children six counters. Ask the children for one way to put the six counters in equal groups. Show all the ways that are suggested. Keep asking until you get all the possibilities. (Two groups with three counters in each group, three groups with two counters in each group, six groups with one counter in each group.)

#### Doing the Investigation

Tell the children they are going to work with 12 counters and see how many different ways they can put them in equal groups. Ask the children to draw pictures of all of the ways that they find. Answers:

- Two groups with six counters in each group.
- Three groups with four counters in each group.
- Four groups with three counters in each group.
- Six groups with two counters in each group.
- Twelve groups with one counter in each group.
