# Bay Area Skydiving Math

Everyone has heard of skydiving, probably because it’s such a risky and exciting sport! There are people skydiving all over the Bay Area, so let’s learn more.  Have you ever wondered, how does skydiving in the Bay Area work? How do humans survive jumping out of an airplane, anyway?

Well, the jumping out part is pretty self-explanatory. However, the parachuting part requires a bit of math to understand. Basically, the greater surface area ( another math concept!) of the parachute increases the air resistance on the person falling to the ground, allowing them to softly and slowly land. Air resistance is caused by an object pushing through the air molecules in the atmosphere, much like how you have to push through water when swimming.

The reason we can’t just jump out of planes and survive without a parachute is our velocity. The gravity of the Earth makes us accelerate as we head towards the ground, until our air resistance cancels the force of gravity out, and we read our terminal velocity. Though at a certain spot our velocity does not increase, this terminal velocity is still fast enough for us to crash against the ground! This is where, once again, a parachute comes in.

The air resistance is increased by the parachute, and therefore the terminal velocity is decreased ( by about 90%). This allows the skydiver to land safely.

# Amusement Park Math Problems in the Silicon Valley

A great book to get at a library in the Silicon Valley is Safari Park by Stuart Murphy is a story almost any child can relate to. When Grandpa gets 100 tickets to an amusement park, he divides them evenly amongst his five grandchildren. The children can choose to spend the tickets as they please. With each ride costing a different number of tickets, the children have to decide which rides they want to go on and how to best spend their tickets. Your child can follow along with the children in the story and figure out if there are enough tickets to go on all of the rides they want. The author suggests giving your child twenty pieces of paper to act as tickets so they are able to follow along with the story. By actively reading Safari Park to your child, you will help them learn how to find an unknown in an equation and manage tickets/money appropriately in order to purchase all of the items they desire. Safari Park will teach your child practical math skills and is a recommended for young children in the Silicon Valley before they head to Great America in San Jose.

# Money Math in Palo Alto

Less Than Zero by Stuart J. Murphy is a wonderful math story of Perry the penguin who wants to buy an ice scooter but does not have enough clams to do so. In this story, clams are used as a form of currency that is equivalent to our dollar bills. While saving up for his scooter, Perry keeps track of how many clams he has on a graph. The story Less Than Zero will teach your child how to graph and use money. When Perry first learns to use clams, he spends all of them and has to borrow clams from friends. He soon realizes that borrowing money from other people only increases his debt, hence the title less than zero clams, and he will need to earn more clams to get to his goal of buying an ice scooter. Eventually, Perry finds a job and saves up enough clams to get his ice scooter. Perry’s persistence will teach your child that they are able to save up money to purchase items that they really want. If they want something badly enough, they will find ways to control their impulse to spend money on items they want simply because they are available. As your child follows Perry’s graph, they might even be inspired to make their own.

A great way for you and your child to spend time together while doing math is by taking your child to Palo Alto’s ice skating rink! Use the same techniques Perry used with your child. Give your Palo Alto child a currency that he or she would need to convert to dollars. Your child will not only have fun reenacting Perry’s dilemma, but he or she will also get to practice their math skills. Less Than Zero will teach your child valuable skills and I definitely recommend this book to all young children in the Palo Alto-Menlo Park area.

# Halloween Math in Palo Alto

In Pigs go to Market, Amy Axelord incorporates math into a fun Halloween-themed story. When Grandma and Grandpa Pig eat all of the Halloween candy, Mr. and Mrs. Pig and their piglets are forced to take a trip to the supermarket to purchase more candy for their guests. Much to their surprise, Mrs. Pig wins a free five-minute shopping spree. On the car ride home, the pigs and their piglets decide to open up the boxes of candy to celebrate their good fortune. In a brief period of time, they manage to scarf down all of the Halloween candy they just got at the store. Given the price per pound, quantity, and weight of the candy, the child is directed to calculate how much candy the pigs ate and how much it would have costed them to buy those items had she not won the free shopping trip in Palo Alto. The Pigs make going to the market an adventure and this story will leave your child eager to go to the Palo Alto stores with you so they can weigh out items and calculate the cost! Pigs go to Market is a fantastic way for your child to practice these skills and build on their math knowledge. Head over to Books Inc in Palo Alto to pick up this wonderful story.
