"Pinapples, unlike people, don't have bilateral symmetry"
From Sima: Our small crew today engaged in a variety of activities: working on puzzles that required sequencing & multiples; solving Once Upon a Time problems, involving time measurement; playing Frac-Jac and other games that practice adding fractions; or solving the Frog & Toad puzzle. After lunch, we watched two mathematical short videos by mathemusician Vi Hart: the club favorite Wind & Mr. Ug, about mobius strips, and Spongebob's Pineapple Under the Sea, about Fibonacci numbers.

Math club
From Sima Misra:
Today in Math Club, we had lively problem solving in action with a magic card trick. Most students discovered it helped to work backwards and record their attempts to figure it out--some will still be working on it over spring break! Others explored symmetry and area with the Part & Whole problems, or worked on some challenging puzzles.

From Sima Misra, about today's math club:
We welcomed two third graders to math club today, Hannah and Talia, who tried out the Wheel Shop problem, stretching their algebraic thinking and number fluency, and played Oddball, another version of Poison/Nim. Many of the 4th and 5th grade students enjoyed working on the different Sudoku puzzles, and I shared a strategy of keeping track of which numbers are possible in any given square using dots. Finally, we all puzzled over one of the several "Liars & Truth Tellers" problems. This is a great one to talk about at the dinner table:
There is an island in the middle of the ocean where there are two kinds of people: the liars and the truth-tellers. The liars always lie. The truth-tellers always answer the truth. You come to a fork in the road and need to know which way to turn to the village. Someone is at the intersection and can answer one yes or no question. You do not know if she is a truth teller or a liar. What should you ask her to learn which way to go?

Math Club!
We celebrated "Pi Day" in Math Club today with circle problems and ollalieberry pie, even though Pi Day is actually on Thursday, March 14 (3.14). Students measured the diameter and circumference of many round objects, looking for patterns, and found that the circumference was a little more than 3 times the diameter--a key to why the mysterious number Pi is so important. Other students pulled apart a pizza problem, figuring out how much to charge for differently sized pizzas and slices given the cost of a small pizza and its area in square inches. Next math club on March 26.

Today's math club blog post
Sent by Sima Misra, Differentiated Curriculum Specialist:
Today in Math Club students enjoyed puzzling over how to buy 100 candies with $15 if cotton candy costs $1, candy bars 50 cents, and gumballs 5 cents (clearly an old problem, given the costs!). There were also geometric puzzles carving out equal area, a word puzzle similar to Sudoku, a zigzag puzzle, and some Chinese New Year puzzles, since this Sunday is the start of the Yin Water Snake year. Finally, some students learned a new game which would be easy to play at home--Fantastic Four.

Here's what Sima passed on about today's Math Club:
Our focus in Math Club was on geometry today. Students used tangram puzzles to do the Tangram Polygon Super Challenge, making 5 different polygons from 1-7 tangram shapes. They also did different levels of the Polly Gone problem, building the biggest pen possible from 40 cubes, or figuring out the area of polygons and creating different parallelograms from them. Other students spent time figuring out an Alphametrics problem (substituting letters for numbers) to do some algebraic thinking in our Math Club Puzzles. No math club next Tuesday because I will be out for Professional Development.
