Your children a couple of homework assignments this week.
1. Check out a few of the Rube Goldberg machines I have linked below. This will help them get ideas.
2. Bring in materials that may be used in a machine and/or prebuilt portions of the machine.
3. Post any cool Rube Goldberg videos in the comment section. (Be sure that it is appropriate for 4th graders.)
In the coming weeks, your child's Rube Goldberg coach will be contacting you via email. Please ask your child what their coaches name is so that you can be on the lookout for an email from them.
