Mark Saul's visit to LCS.
Part of our school vision is to connect with the community. Today the 9th and 10th graders had an opportunity to interact with the executive director of Julia Robinson Mathematics Festival, Mr Mark Saul.
Julia Robinson Mathematic Festival partner with the National Museum of mathematics to provide mathematics curricula through math circle and clubs to reach more than 1,000 students in New York, San Francisco Bay area and Washington DC. The curricula are designed to encourage a sense of discovery and excitement about mathematics through problem solving and interactive exploration. They support events that inspire K – 12 students to explore the richness and beauty of mathematics through collaborative and creative problem-solving. Refer to their website for resources http://jrmf.org/
Mark and the students played a simple word game which got them exploring the notion of proof, implication and logical deduction - the heart of the mathematical experience. The game involved guessing the secret word Mark had in mind.
At first the students were polite, but skeptical. They started playing the game by trying to guess the word. After a certain point they made a logical inference to derive the information from the clues they already had. This understanding quickly spread through the class and the room was filled with noisy learning.
There was group sharing and eventually they found the word.The students collaborated and were enthusiastically working along with him.The moment of "AH! We got it" was heard after they discovered the concept behind this activity.
In the afternoon, Dr. Saul spent some time with an IB Mathematical Studies class, examining patterns. We started with a game of standing up and sitting down, with the rule that a person can stand up or sit down only in certain cases.
From this we developed a table of ones and zeros, and by the end of the class we had taken a look at sets, subsets, a cube, and the placement of the cube on an xyz (3-dimensional) grid. We saw the interconnectedness of mathematics, and the similarity of patterns when moving between algebra and geometry.
We are glad that Mr Mark took some time from his schedule to be with us.
