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.
Remember, you can always send feedback to the Bing in the Classroom team at You can learn more about the program at bing.com/classroom and follow the daily lessons on our Partners In Learning site.

She works with playwrights from ages four to ninety on developing new work and is especially interested in alternative literacies and theater for social change. A graduate of Swarthmore College, she currently works in the Artistic Department of the Wilma Theater and, in addition to teaching, is a freelance actor and dramaturg. In 2011, Nell was named a Thomas J. Watson Fellow and spent her fellowship year traveling to seven countries studying how people get their names.
This lesson is designed to teach the Common Core State Standard: Number & Operations-Fractions
CCSS.Math.Content.4.NF.A.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
CCSS.Math.Content.4.NF.B.3.b Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = /8 = 8/8 + 8/8 + 1/8.
CCSS.Math.Content.4.NF.B.3.d Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

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.

The big game of today’s inaugural FIFA World Cup playoffs is in nearby São Paulo, the sprawling metropolis south of here. But over the course of the next 30 days, Rio de Janeiro will host its share of the games as well. Brazil has hosted the finals once before, in 1950, which resulted in a historic loss on home turf to rival Uruguay. But only Brazil has played in every World Cup tournament, and no other country has taken the World Cup title more often, with Brazil having captured a total of five titles since 1930.
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.

The 19 World Cup tournaments have been won by eight different national teams. Brazil have won five times, and they are the only team to have played in every tournament. The other World Cup winners are Italy, with four titles; West Germany, with three titles; Argentina and inaugural winners Uruguay, with two titles each; and England, France, and Spain, with one title each.
Students should think about what a numerator and denominator each represent (and if necessary or helpful, use the Bing Search Bar to find their definitions) and conclude that the total number of world cups (19) should be the denominator. The number of times various countries have won should then fill in as the numerator because they are a part of that total number.

How could you create a fraction to represent the number of times Brazil has won the FIFA World Cup out of the total number of championships there have been?
(Possible queries: “FIFA World Cup records”, “how many times has Brazil won the FIFA World Cup?”).
From en.wikipedia.org/wiki/FIFA_World_Cup_records:
Brazil has won the FIFA World Cup 5 times and there have been 19 total championships.
Students should think about how to represent this amount as a fraction and determine that the total number of championships (19), would be the denominator, and the number of times out of that Brazil has won (5) would be the denominator. Therefore the total number of times Brazil has won the FIFA World Cup can be expressed as 5/19.

(Possible queries: “FIFA World Cup records”, “how many times has Italy won the FIFA World Cup?” , “how many times has Germany won the FIFA World Cup?”).
From en.wikipedia.org/wiki/FIFA_World_Cup_records:
We know that Brazil has won the FIFA World Cup 5 times, Italy has won 4 times and Germany has won 3 times. There have been 19 total championships. If we translate these into fraction equations and compare them:
Italy 4/19 < Brazil 5/19
Germany 3/19 < Brazil 5/19
Germany 3/19 < Italy 4/19

From en.wikipedia.org/wiki/FIFA_World_Cup_records:
We know that Brazil has won the FIFA World Cup 5 times, Uruguay has won 2 times and Argentina has won 2 times. There have been 19 total championships. If we translate these into fraction equations and compare them:
Uruguay 2/19 < Brazil 5/19
Argentina 2/19 < Brazil 5/19
Uruguay 2/19 = Argentina 2/19

England 1/19 < Brazil 5/19

This slide is a chance to summarize the information from the previous slides to build your final answer to the question. Based on the information they have gathered, students can write equations comparing the fraction of the total championships that each country has won. Answers will vary. For example:
Brazil 5/19 > England 1/19
Germany 3/19 > France 1/19
Uruguay 2/19 > Spain 1/19
