- Have the children randomly alternative their commencement bill of fare (it mightiness travel practiced to travel inward groups).
- Give them ii minutes to notice objects or discovery a agency to stand upwards for their problem. (For my event they mightiness alternative upwards vii toy cars as well as present you lot 5 driving away OR vii pencils inward a loving cup as well as 5 are taken out.)

- Repeat ii to a greater extent than times.
On Sat I'll travel having a invitee blogger here. Be certain to come upwards dorsum as well as banking concern gibe it out : ) And recall to link upwards whatever of your math weblog posts : )
