This engaging activity is the perfect introduction to capacity and measurement units or the perfect addition to math centers. Students work with a partner and take turns flipping over a pumpkin card onto the numbered mats. Students then predict which pumpkin will hold more seeds and record their predictions on the recording sheet. I give my students real pumpkin seeds so they can test their findings! They love this activity! The differentiated version challenges students to take their learning a step further by counting and recording the number of seeds that fit into the pumpkins.
