Balance Scale Measurement Activities for Preschool and Kindergarten

Hands-On Weight & Mass Exploration for Math & Science Centers

Looking for a simple way to teach weight measurement, comparing weights, and measuring mass in your classroom? These balance scale activities make it easy for preschool, pre-k, and kindergarten kids to explore measuring things through hands-on math and science play.

This engaging resource helps kids understand concepts like heavier, lighter, equal weight, and more/less by using a balance scale and everyday materials. It’s the perfect addition to your math centers, science centers, or STEM stations—with just enough structure to guide learning while still encouraging exploration.
