If you repeat this activity over time, older children will get practice in predicting. In the morning, read a thermometer or listen to the radio to hear the weather forecast. Then, ask your children what clothes they should wear that day. This will give meaning to the temperatures you just read or heard. You might even compare the temperature inside with the temperature outside .
Traffic signs are a good place to start.
Yield signs are triangles, highway signs are rectangles, and stop signs are octagons. Ask children about the signs they see. Older children may talk a lot about what they saw. That sign is a rectangle. It has 4 sides and 4 corners.
