Kindergarten Lean

Last week I had the opportunity to join my son, Bret, for lunch at his school in honor of National School Lunch Week. It is not often that I get the chance with my work schedule to visit his school, so I did not hesitate when I had the chance. Bret is in kindergarten, his very first year in school. I even arrived a little early to see him in class before we had lunch together. It was amazing to see all the energy, enthusiasm and eagerness of a classroom full of kindergarten students.

As some of you know, 5 year olds sometimes have a short attention span, have bursts of raw energy and ask a lot of questions (like my favorite, why?). It's funny how you don't have to teach a 5 year old the concept of asking the 5 whys. Now imagine a room full of 5 year olds. Without a system to create an orderly learning environment, chaos would be unleashed. Of course, Bret's Kindergarten Teacher had a system but what surprised me was the lean principles (although not labeled as lean) I saw in action to keep things in order and flowing. I'll call it Kindergarten Lean, or lean basics for providing an efficient, organized learning environment for 5 year olds.

Before lining up for lunch, all the kindergarten students helped clean up the room from an active play period. Each toy had a designated place to store them, a home location that was clearly labeled. Since most 5 year olds are not able to read yet and have limited sight recognition of words, I assume the labels are for the teacher. Despite limited reading skills, these kindergarten students knew the proper home location for each toy. In a flash, they had the entire classroom back in order. Even the teacher and her aide joined the students in the clean up, working together. It certainly looked like a quite efficient 5S process with (management) leading by example to me.

In Bret's kindergarten class, there are 24 students. The classroom layout groups the desks in clusters of 5 desks with each student assigned a desk (labeled with their name). After cleaning up the classroom, each kindergarten student returned to their desk, or their home location. The teacher released the class by cluster (5 at a time) to go to the bathroom and wash up before lunch. As they returned, another set of 5 was released to the bathroom. This process reduced the congestion in the bathroom that would be created if the entire class went all at once. Likewise, the school staggers the lunch times for the different grade levels to eliminate the burden on the lunchroom. This kept the lunch line short and only requires a small lunchroom for the school. It certainly looked like level loading (Heijunka) for the bathroom, lunch staff and lunchroom resources to me.

Each kindergarten student has a lunch card used to purchase their lunch (color coded to distinguish it from their snack card) which is kept in a slot hanging on the classroom wall (labeled with their name). The students retrieved their card and returned to their desks, after washing up and before lining up to walk to the lunchroom. The path to their lunch cards is arranged for one-way traffic to the slots and a separate path to return to their desks. This method provided a smooth flow and eliminate bumping into each other. It certainly looked like visual management and FIFO lanes to me.

On the kindergarten chalkboard, the learning goals for the week were boldly written complete with activities to support it. Learning the letter, G g, was a top priority for the kindergarten class, both letter recognition and proper writing. Even the class show and tell for the week needed to be something starting with the letter G. It certainly looked like posted goals and targets (Hoshin) to me.

All these lean principles worked well in the kindergarten classroom not to mention the respect for others, listening skills, politeness, manners, teamwork, punctuality and personal responsibility emphasized by the teacher. It's funny how you can re-learn the basics just by going back to kindergarten. That is probably the most important lean lesson of all. Emphasis is placed on getting the basics right in kindergarten. Just like in kindergarten, we should have the same emphasis on getting the basics right on our lean journey.

Another great post, Mike. One that many of us can relate to.

We often approach Lean as Simple. Then we have to explain that simple is not easy and not simplistic. It is simple.

As for children and "Why?" it is too bad that the later years in school does not motivate them to continue asking that question. We might not be able to control the destination as easily as the rote "teaching to test" most students receive today, but we would have people who were used to delving into issues with honest questioning and following the data where it led them.

Brilliant. If we could only maintain these kaizen basics from kindergarten through the 12-year mandatory education period!

Mike, very good post! I can relate, too, because I have two kids in grade school: one in nursery, the other in Grade 1. The things you described are true, and it's very clever of you to relate it to lean practice. Keep up the good work!

Hi Mike
Its great analogy you had brought in to convey the lean message !

I am sure there are lot of instances in everyday life where we imbibe the lean principles.
If you have something interesting like this to draw parallel to Sports and gaming , I look forwrad to hear from you.

Very interesting post. I couldn't help wondering who the customer is for a kindergarten and what the value is? This is a question I often ask about education.

If the student is the customer, what is the value that they recieve from what occurs in the classroom? If society is the customer, what is the value? If industry is the customer, what is the value?

In any case it is interesting to also ask what is value add activity in the classroom and what is waste?
