Students will directly compare the capacity of two containers by pouring and observing, using vocabulary like "holds more," "holds less," and "holds the same."
Capacity is how much a container can hold. At the Pre-K level, children explore capacity through hands-on pouring and filling activities.
To compare capacity, children pour from one container to another: - Fill one container - Pour it into the second container - Observe what happens
If it doesn't all fit → first container holds more If it all fits with room left → first container holds less If it all fits perfectly → they hold the same
Holds more: Container has greater capacity
Holds less: Container has smaller capacity
Holds the same: Containers have equal capacity
Full: Container is filled to capacity
Empty: Container has nothing in it
Overflow: Too much to fit; spills out
Containers: cups, bowls, bottles, buckets, pitchers Filling materials: water, sand, rice, beans, small blocks
Capacity is essential for: - Cooking and baking - Pouring drinks - Understanding containers - Science experiments - Everyday problem-solving
Children need many experiences: - Compare different-sized containers - Try different materials (sand vs. water) - Use various types of containers - Sometimes use very different sizes, sometimes similar
Tall = Holds more Children may think taller containers always hold more, but a wide, short bowl might hold more than a tall, thin bottle.
Same amount = Same shape Children might think only identical containers can hold the same amount.
Solution: Provide many direct comparisons with varied shapes
Mastery indicators: - Correctly identifies which holds more after pouring - Uses vocabulary appropriately - Can explain reasoning: "This one overflowed" or "There's room left" - Makes predictions before testing
Support: - Use very different-sized containers (obvious differences) - Provide hand-over-hand pouring assistance - Start with just two containers - Use consistent containers initially
Extension: - Compare three containers: most, least, medium - Find containers that hold the same amount - Estimate before pouring - Count how many small cups fill a large container
Families can practice: - Bath time pouring games - Kitchen helping: measuring cups - Water play outdoors - Comparing container sizes - Pouring drinks
