Chapter 4

Part 1: Home and School Investigation

Send the Letter to Family (PDF file) home with each child. Once all of the children have brought back their tally charts, discuss what they found. Use the following in the discussion.

  • Raise your hand if yellow was chosen by most people in your family. (Count the hands and write yellow on the board with the hand count next to it.)
  • Raise your hand if blue was chosen by most people in your family. (Count the hands and write blue on the board with the hand count next to it.)
  • Raise your hand if red was chosen by most people in your family. (Count the hands and write red on the board with the hand count next to it.)
  • Which color was the family favorite? (Answers may vary.)

Part 2: Be an Investigator

A good time to do this investigation is after Lesson 6 on using a graph.

Materials

Introducing the Investigation

Introduce the investigation by telling children that they are going to keep track of the weather each day for ten days. Present the Investigator Worksheet. Tell them they will color in the bar graph each day to include whether the day was sunny, cloudy, or rainy. At the end of the ten days they will be able to see which type of day they had the most. You might want to ask the children to predict what type of weather they think they will have the most.

Provide students with the Investigator Worksheet (PDF file).

Doing the Investigation

Each day for ten days have the children fill in their bar graph after discussing as a class what kind of day it was. Each day ask questions such as:

  • What kind of day have we had the most so far?
  • How many sunny (cloudy, rainy) days have we had so far?

When the ten days are over, talk about which kind of day you had the most. Then have children look at the weather graph on page 99 of their student book. Compare the weather on that chart with your class charts.
