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, put the children in pairs to share their pictures with each other. Have the children describe their pictures, using position words.

Part 2: Be an Investigator

A good time to do this investigation is after Lesson 6 on creating patterns.

Introducing the Investigation

Tell children they are going to work in a group to create a pattern dance. Ask children to name some of the things they might do in their dance. Have them make suggestions like hopping, jumping, clapping their hands, etc. Tell children that they will share their dance with the class and the class will try to figure out what the pattern is.

Put children in groups of six to do the activity.

Doing the Investigation

There are two ways children might create their dance.

  • Every child in the group does each movement at the same time. For example,
    • all children clap their hands once
    • all children jump twice
    • all children clap their hands once
    • all children jump twice, etc.
  • Children stand in a row. One child does a movement, followed by the next child, etc. For example,
    • first child claps hands once
    • second child jumps once
    • third child jumps once
    • fourth child claps hands once
    • fifth child jumps once
    • sixth child jumps once

Either of these ways is fine. Help children develop the way they choose to do the activity.

When children have completed their pattern dance, have each group show their dance to the class to see if the children in the class can figure out what the pattern is and act it out.
