materials needed for measurement math unit

Hi Parents,
We are starting our last math unit of the year, capacity, weight, measurement.

I'd like for my students to get hands on experience with different capacity units, so if you have any clean, empty bottles, please send them in. I want the units of measurements to be on the bottles. Examples would be:
shampoo bottles, water bottles, lotion bottles, empty cereal boxes (with weight). Just send them in with your children.

Thanks so much!
Ms. Howard
