During math time the past few Katie days, we have continued with subtraction games and done some more graphing activities. Graphing is multi-layered at this age, as it allows learners to organize and classify things into categories, and make representations of their data. We also interpret our data based on our representations. Then we are able to ask and answer questions about the categories. For example last week we graphed a big box of animal crackers. We also graphed how many teeth each of us have lost and compared our results. (Questions included: Which animal cracker shape did we get the most of? How many lions and elephants combined did we get? How many more teeth did Mali lose versus Sabrina, How many teeth all together have the kindergarteners lost, etc…)
 
Part of our teeth graph included reading the book Throw Your Tooth on the Roof a great book about the different tooth traditions around the world. I read a bunch of different ones and then learners had the chance to ask for the tradition of a specific country that their relative or friend is from. We learned about the traditions of Sri Lanka, China, Japan, South Africa, New Zealand and much much more! (A class favorite was Raton Miguelito in Colombia who comes and takes your tooth.) 
 
We also compared two non fiction books to see what characteristics they share and what makes them different. One was an informational text on sea turtles, the other a non-fiction story about Chippy the Sea Lion who got lost in the Delta a few years back. After a discussion, we made a Venn Diagram comparing the two books. (They both were about animals and true, but one contained a table of contents, index and text boxes with facts.) 
 
For art we have been working on some top-secret projects that hopefully will find their way to all the mothers in the crowd come Sunday! We also started making Sun Prints, a wonderful printmaking technique, also called cyanotype, that uses sunlight as a developing agent. Sun Prints were originally developed as a teaching tool by educators at the Lawrence Hall of Science. Basically a negative image is made by placing an object (in our case a variety of plants) upon special paper and then exposing it to sunlight for a few minutes. The paper  retains the image of the plant after it is rinsed in a tub of water. Once the paper dries, parts that were exposed to the sun will turn a shade of blue, while parts that were covered by the plant will remain white.
 
Here are some pictures of our Sun Prints and a first grade phonics activity we did around making compound words. Hope you all have a wonderful weekend and HAPPY MOTHER’S DAY!
