1. Teacher Guide
This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

This lesson is designed to teach the Common Core State Standard: Measurement & Data.
CCSS.Math.Content.4.MD.A.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...
CCSS.Math.Content.4.MD.A.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

Having this up as kids come in is a great settle down activity. You can start class by asking them for thoughts about the picture or about ideas on how they could solve the question of the day.

From the slopes of Tibidabo mountain, we see the Fabra Observatory, still high up enough in the hills to avoid light pollution from bustling Barcelona below. What isn’t seen here is the variety of entertainments offered at the top of Tibidabo, including an amusement park and an ornate Catholic church called Temple de Sagrat Cor.
Depending on time, you can either have students read this silently to themselves, have one of them read out loud, or read it out loud yourself.

There are a couple of ways to use this slide, depending on how much technology you have in your classroom. You can have students find answers on their own, divide them into teams to have them do all the questions competitively, or have each team find the answer to a different question and then come back together. If you’re doing teams, it is often wise to assign them roles (one person typing, one person who is in charge of sharing back the answer, etc.)

You can adjust this based on how much time you want to give kids. If a group isn’t able to answer in 5 minutes, you can give them the opportunity to update at the end of class or extend time.

You can ask the students verbally or let one of them come up and insert the answer or show how they got it. This way, you also have a record that you can keep as a class and share with parents, others.

(Possible queries: Tibidabo Amusement Park tickets’”, “Price of entry Tibidabo Amusement Park”, “how much does Tibidabo Amusement Park cost?”).
From
The choice of ticket includes all the rides and activities in the park. However, access to rides depends on the visitor´s height:
Entrance €
Entrance for those under 1.2m €
Entrance for those under 90 cm 0 €

How tall are most kids? What can we assume about their height, in meters, feet, and inches?
(Possible queries: “average height of kids”, “how tall is the average 10 year old?)
From
At 10 years old, the average girl is 54 inches tall and weighs 72 pounds. At 10 years old, boys are 55 inches tall and weigh 70 pounds on average.
Answers will vary depending on the age of the average child that students look up. Students should recognize that the height of a “kid” can range drastically depending on the age and genetics. In general, however, they should recognize that many kids are in the 3-5 foot range, which would be somewhere between 1-2 meters. They can then use the Bing Search Bar to convert feet to meters. The exact answer is less important than students figuring out these conversions conceptually and estimating that most kids would fall somewhere in the 1-2 meter range (and most likely, closer to 1 than 2).

How tall are most adults? What can we assume about their height, in meters, feet, and inches?
(Possible queries: “how tall is the average adult?”, “how tall are most adults?”).
From
The average adult American male is 5 feet 9.3 inches tall, according to data collected by the Centers for Disease Control and Prevention between 2007 and 2010.
Answers will vary depending on the gender and background of the adult that students look up. Students should recognize that the height of an adult can range drastically. In general, however, they should recognize that most adults are in the 5-6 foot range, which would be somewhere between 1-2 meters. They can use the Bing Search Bar to convert feet to meters. The exact answer is less important than students figuring out these conversions conceptually and estimating that most adults would fall somewhere in the 1-2 meter range (and most likely, closer to 2 than 1).

What currency is used in Barcelona? How could you convert this to US dollars?
(Possible queries: “currency in Barcelona”, “money in Barcelona”, “Barcelona exchange rate”).
From
In Barcelona, the Euro is the common currency.
Once they have this information, students should then look up a currency converter or just use the Bing Search Bar (“US dollars to Euros”) to find that 1 US dollar = .73 euros. (Note: this exact rate may change daily!)

12. If a family of four (two parents and two kids) were going to spend the day at Barcelona’s Tibidabo Amusement Park, how much would this cost them in US dollars?
This slide is a chance to summarize the information from the previous slides to build your final answer to the question. The students who looked up the exact price of tickets should share that the fee for entrance is euros for most, and euros for those under 1.2 meters. Students should then share the information they’ve gained about height to say that it’s probably fairly safe to assume that the two children in this family are under 1.2 meters, but that the two adults would most likely be over 1.2 meters. (Though of course this would depend on age, genetics, and a variety of other factors). Students should then put this information together to figure out the price in euros for the entire family to enter.
2 x euros (price for kids) + 2 x (price for adults) = 20.6 euros + 57 euros = 77.6 euros
Students should then convert this price in euros to US dollars. They should share the information they’ve gathered that 1 dollar = .73 euros and create a formula to solve this.
.73 euros / 1 dollar = 77.6 euros / x dollars
X = $106.30
It would cost approximately $ for this family to spend the day at Tibidabo Amusement Park.
