Show and Tell Science & Math

STEM Activities show n tell


Show and tell is an age-old activity that happens in many classrooms. Put an academic spin on this activity and support standards at the same time. The children have lots of fun while learning set comparison using science materials and a simple graph.

Set Up ideas

You'll need to make and send appropriate notes home for children to bring something in. Try to stick to small, relatively easy items to find like nature items.

Let’s Get Started

Before starting show and tell, you'll need to create a floor graph. You may be able to find a commercially made floor graph, or you can simply create your own by taping 2-3 long strips of butcher paper together to form a graph.


Choose a science topic that the children can participate with by bringing items from home for show and tell. You may wish to choose a topic related to something else you are studying.


Whatever the children's usual procedure is for sharing, add another procedure by deciding 2-3 categories on the floor graph to divide the shared materials.


As each child completes their time sharing, have them place their show-and-tell items into the appropriate column of the floor graph.


After everyone has shared, compare the sets on the floor graph. Work together to determine which set has the most and which has the least..

The children will do most of the talking with this activity! Depending on the topic and what you are categorizing, you may need to discuss the children's items with them to help place them in the correct spot on the floor graph.
