Fractions

Confused about fractions? New to it? Just need a review? Kids as well as adults are welcome to participate in this workshop series aimed at understanding the idea of a fraction as a number, how to calculate with fractions, and how they relate to percents, ratios and decimals. All workshops emphasize respectful comraderie, cooperative learning, question-asking, and use a hands-on, playful, student-led approach.

Fractions I

This course will focus on wholes, halves, fourths, eighths, thirds and sixths. You will learn to represent these fractions in multiple ways, understand the different parts clearly, place them on a number line, combine them with each other, learn one easy method to create an equivalent fraction, and practice explaining your work to others.

Fractions II

This course will focus on adding, subtracting, multiplying, dividing and simplifying any type of fraction within the context of daily life such as cooking, budgeting, traveling, event planning, etc. You will practice representing the same quantity as a fraction, percent, division problem, ratio and decimal, placing them on a number line and comparing them. You will work in teams and present your findings to the group.

Patterns In Mathematics

When you start paying attention to patterns in the world, you gain insight and the ability to predict the future. Weather forecasters predict the weather based on nature's weather patterns that repeat themselves a certain way with a predictable outcome. When you start to be able to assign numbers to real objects and then study those number patterns, you can obtain fascinating information about the world. Learn about and practice extending a pattern with picture and number sequences, square numbers, cubed numbers, triangle numbers, Fibonacci numbers, Pascal's triangle, Magic Squares, fractals, tesselations, rhythm and symmetry. All workshops emphasize respectful comraderie, cooperative learning, question-asking, and use a hands-on, playful, student-led approach.

Secret Codes

Have you ever wanted to share messages with your friends that nobody else could read? Have a secret language? What would it be like to be a code breaker or a spy carrying coded information? There are many ways in which people have figured out how to disguise messages. Some are simple and others, much, much more complicated. This is called Cryptography

Come learn how to encrypt and decrypt ciphers and codes. We will cover Caesar Ciphers, Pigpen Ciphers, Book Ciphers, Substitution Ciphers, Cipher Wheels, Scytales, public keys and the difference between ciphers and codes.

You will get to practice encrypting a message and then exchange with another participant to practice decrypting their message. Every participant will get to take home a resource sheet that reviews the workshop's content, links to great websites and additional ciphers to solve.

Algebra

Algebra is the study of relationships. Come learn about this often intimidating subject in this 2-day workshop series. All workshops emphasize respectful comraderie, cooperative learning, question-asking, and use a hands-on, playful, student-led approach.

Algebra I

You will be introduced to the language of algebra, practice translating word problems to an algebra expression or equation, learn how letters (variables) are used to express the unknown, learn how to solve for x in simple equations, and plot points on a coordinate plane.

Algebra II

You will learn how to find the slope of a line and through solving a story problem learn about linear equations and how to express them and look for patterns to find the missing parts. You will also learn what a function is, including the concepts of range and domain. We will work in teams to create function machines.

Times Tables

Learn your times tables already! Knowing them quickly will help you with day to day mental math calculations, estimating at the store, making sure you are receiving the correct change or getting the advertised deal. It will also help greatly when you need to calculate fractions, ratios, algebraic equations and angle measurements among other topics. Instead of stumbling on 8x6, you will be able to focus on learning the new concept.

There are so many ways to explore patterns and structures in the times tables that are fun and help you learn them by heart. You will also get a list of great online games and apps that I recommend and my students love. You will NOT use flashcards and you will NOT be competing with anyone. So, relax, and come learn the fun way!

All workshops emphasize respectful comraderie, cooperative learning, question-asking, and use a hands-on, playful, student-led approach.

This workshop is on the 14th and repeats on the 28th, same time, same place. You are welcome to attend one or both.

Math And Art

Are you a creative person who loves to draw? Me too! This doesn't exclude you from enjoying the beauty mathematics has to offer.

Math is about patterns and relationships and how things change over time. If you record these artisticly, you can create some beautiful art! This session is 2 hours long so you actually have time to create something to take home with you. You will be seated in table groups and materials will be provided.

A lot of mathematically inspired art is geometric. Some forms of art you will learn about are tesselations, Islamic Tiles, 3D nets that fold into boxes, fractals, snowflakes, and pentagon/hexagon/octagon stars. After learning about these various art forms, you will get to choose what you would like to work on and take home. You will also get to take home a "how to" for the other types of art discussed. We will take a tour break to walk around the room and see what art others are creating.

Although many materials will be provided, it's always nice to not have to wait until someone else is done, so feel free to bring any of the following for your own personal use or to share: ruler, compass, fancy markers/pens/pencils, scissors, stencils, etc. If you do so, you are responsible for keeping track of your own belongings.

Logic Puzzles

If Mary wore blue, the girl across from her ate ice cream and Marco had a pet fish, who sat next to Luis?

Have you ever come across a logic puzzle that made you dizzy just by reading it? Sometimes called Einstein Puzzles, this type of logic puzzle (in which you must figure out who is wearing what color, what order they are seated in, what pet they each have, etc.) uses deductive reasoning skills. This is a skill in which American students are sorely lacking, compared to our global counterparts. Its also so much fun and quite addicting!

You will be guided through one puzzle, step by step, to completion. Afterwards we will split into groups and you can choose to work on your own, with your family or friends, or with me in second guided session.

There will be numerous puzzles from which to choose to solve and take home with you as well as resources on where to find more Online, including a great app.

Geometry

We will get right down to the point in this workshop, literally. From a point to a line, to 2D and 3D shapes. All workshops emphasize respectful comraderie, cooperative learning, question-asking, and use a hands-on, playful, student-led approach.

Geometry I

We will learn about geometry and generate questions by folding circles. Concepts covered will include various ways to measure shapes and angles and why you might want to do so (perimeter, area, volume, diameter, circumference, radius)

Geometry II

Starting from a complex, real-world problem, we will work together as a group to learn the "rules" of geometry and solve smaller problems to gain the skills and understanding needed for the larger problem. You will work in teams of 2-3 to solve a second, similar problem and present your findings to the group.

Math Games

You hear "Family Math Night" and groan a little. The teacher sends home a "game" to practice some mathematical operation or drill skill and parents have to play it three times or some such thing and sign off on it. Research has shown, just like reading at home with your kids improves language literacy, doing math at home with your kids and in front of your kids, improves their math literacy.

Luckily there are many games out there that build mathematical skills such as logic, reasoning, mental math, strategy building and flexible thinking and are also SO FUN and ADDICTING that you dont even think about it as math and the whole family actually wants to play.

Here is a sample of the games we will explore: SET, Sumoku, Blokus, Ticket To Ride, Mancala and Mastermind. (SET is my all time favorite. If you don't know this one, you are in for a treat!)

An hour is so short, this won't be a full gaming night, more a review of the games. You will receive a chart of games, what math skill each promotes, number of players needed, time required, cost and where to buy. You will hear a brief description of approximately 15 games and then have the opportunity to either play one game for a limited amount of time or walk around to watch 1-5 games in action depending on the number of participants that night.
