Materials Spotlight: The Interdependencies Cards

Meagan Ledendecker • December 11, 2023

In Montessori, we talk a lot about independence. Yet interdependence is another vital aspect of our humanity and a key part of Montessori learning communities.


All of us depend on the help of other people. We are social beings and we evolved to be interdependent with our fellow human beings. None of us exist in isolation. 


Interdependence is woven into how our classrooms operate and at the early elementary level we also have a material that provides children with a window into how humans depend upon each other.


The Interdependencies Cards


To introduce this material, we start by gathering a small group of children and asking about a recent meal or their favorite foods. When someone mentions bread, or perhaps the adult offers that they ate toast that morning, we ask where the bread came from. Together the group follows the trail of origin of the food, exploring questions like: And where did the supermarket get the bread? Who baked the bread? From where did the baker get the flour? Finally, the trail leads back to the farmer. 


As a group, we marvel at how many people it takes to bring bread to us. If the children are interested, we continue with other food or breakfast items, always arriving at the beginning when the farmer has planted the seeds.

 

At this point, we often go to the shelf and get the first set of Interdependencies cards.


Where do we get our food from?


These cards provide a physical representation of the group’s discussion of the origin of our food. Because someone bought their bread at the supermarket, we place the “shopkeeper” card. We continue explaining how the shopkeeper bought the bread from the baker, placing the “baker” card to the left of the shopkeeper card. We continue the process until the array is complete: the farmer - the miller - the baker - the shopkeeper.


We comment on how many people are involved in the process before asking another question: How does the miller get wheat from the farmer?


The children discuss and we explore how the farmer needs some way to get the wheat to the miller. Perhaps a truck is used, or maybe a train, but some form of transport is needed. We then place the cards to represent that transportation and repeat for other producers. 

 

Then we suggest thinking about the baker a little more. We explore if the baker needs help and can discuss adding a dough maker, oven tender, and packager around the baker card. 


If the baker needs help, then likely the miller, farmer, and even the transporters need help, too! All these people work together to bring us our bread. What would it be like if we had to do it all for ourselves?

These interdependency exercises bring awareness to children in a developmentally appropriate way. Though the materials are quite simple, the children feel great satisfaction from using their reasoning minds to make the chain of production and human work apparent. The cards also help the children order the sequences we discuss. 


Production & Exchange


At another time we use other sets of cards to explore what farmers produce, who depends upon the farmer, and who the farmer needs. When children have worked with these different sets of cards and explored the interconnections, we can use the cards to introduce how goods are exchanged among people and how the medium of exchange today is money. 


We introduce this concept by thinking about how people generally can’t just trade what they produce. The baker, for example, won’t want shoes every day that the shoemaker needs bread! Thus, people invented money, which is exchanged instead. So, when the shoemaker needs bread, she gives the baker some money, and receives some bread in return!

 

We continue in this manner, discussing various exchanges and visually representing the connections by drawing colored lines between the different producers to show how there is a complicated network of goods flowing from person to person and of money flowing in exchange.

Additional Services


Once children appreciate this initial introduction to economic exchange, we explore how each of the people on the cards also needs services like police, roads, water supply, garbage collection, libraries, and health services. 


We talk about how people got together and decided to 'chip in' to pay for these services. Then in the center of the array of cards, we place a card showing a red bowl. We draw a green line to the bowl card and talk about how each person pays some money to a central collection agency. This money is called 'taxes', and the government uses tax money to provide services.

Young elementary students are often fascinated by this work and like to lay out the cards to show different models. Even older elementary students have ah-ha moments as they begin to understand economic concepts and the idea of what taxes represent. Sometimes children even want to make a set of interdependencies cards of their own for some product they choose. At other times children extend the work by organizing Going Out trips to a bakery or a farm. 


Although the material we use to highlight interdependencies is relatively simple and seemingly unsophisticated, it is quite important. Plus, elementary children find the work intriguing and love the message the material conveys.

Did you know that the word "grammar" evolved from "glamour"? This linguistic connection reflects an ancient association between language and enchantment. When we introduce Montessori's sentence analysis work, we offer more than just a lesson—we present an enchanting gift! We regularly witness children falling in love with language as they uncover its patterns and structures. At the elementary level, children possess a reasoning mind, an active imagination, and a deep need for communication. The Montessori sentence analysis activities appeal to these characteristics, helping children connect as they creatively discover the underlying patterns of our language. Why Do We Teach Sentence Analysis in the Elementary? Children are natural pattern seekers. They love to identify and understand structures in the world around them, including language. We want them to fall in love with language. By engaging in hands-on grammar work, children develop an appreciation for the beauty of sentence construction. Sentence analysis provides clarity. Understanding sentence structure helps children write with greater precision and confidence. Analysis leads to synthesis. When children break down sentences, they gain the tools to build more complex and meaningful expression in their own writing. What Sentence Analysis Involves The elementary sentence analysis materials introduce a set of symbols (that correlate to what children have experienced with the Montessori grammar boxes and the symbols for parts of speech), along with color-coded arrows with questions on one side and grammatical names on the other. When breaking apart the parts of the sentence, children first identify what brings the sentence to life: the verb (predicate). To identify the subject of the sentence, children ask the questions from one of the arrows emanating out from the action: Who is it that? What is it? By answering those questions, the children are able to determine the subject. Let’s use a very simple sentence as an example: Josie jumped. The children first identify the action: jumped. They can underline this word in red and then can cut it out or tear it out in order to be able to place the word on the red predicate circle. Then they use the black arrows to answer the question: Who is it that jumped? Josie!
