Meet Cesar Chavez!

Today, we're going to learn about Cesar Chavez, a man who worked hard to make life fair for farmworkers – people who pick fruits and vegetables in the fields. He showed that even one person can stand up for what's right!

Introduce Cesar Chavez and his connection to farmworkers.

Life as a Farmworker

When Cesar was a boy, his family lost their farm and became migrant farmworkers. This meant they moved from place to place, following the crops.

  • Farmworkers often worked long hours for very little money.
  • Their living conditions were tough, and their children couldn't always go to school.
  • They faced unfair treatment and difficult situations.

Explain the challenging life of migrant farmworkers and the injustices they faced.

Standing Up for Justice

Cesar Chavez believed that farmworkers deserved fair treatment and better pay. He helped them organize a union – a group of workers who join together to ask for better working conditions.

  • He taught farmworkers to stand up for themselves peacefully.
  • He used non-violence, like peaceful protests and marches, to bring attention to their struggles.

Discuss Chavez's role in organizing a union and his commitment to non-violent protest.

The Grape Boycott

One of the most famous things Cesar Chavez did was organize a grape boycott.

  • He asked people across the country to stop buying grapes to support the farmworkers.
  • This put pressure on the grape growers to listen.
  • It showed the power of many people working together for justice (fairness).

Explain the concept of a boycott and how it helped the farmworkers. Emphasize "justice."

Cesar Chavez: A Legacy of Fairness

Because of Cesar Chavez's leadership and the bravery of the farmworkers, many positive changes happened!

  • Farmworkers got better pay and safer working conditions.

Reading

Who Was Cesar Chavez?

Cesar Chavez was a famous leader who worked to make life better for farmworkers in the United States. He was born in Arizona in 1927, during a time called the Great Depression, when many people were poor.

A Childhood of Hardship

When Cesar was a young boy, his family became migrant farmworkers. This meant they traveled from place to place, following the seasons to pick crops like grapes, lettuce, and apricots. Life was very difficult for farmworkers. They worked long hours in the hot sun for very little money. Often, they didn't have good places to live, and their children, like Cesar, had to move from school to school or even work in the fields instead of attending classes. Cesar saw firsthand how unfairly farmworkers were treated.

Finding His Voice

As Cesar grew up, he knew something had to change. He believed that farmworkers deserved better pay, safer working conditions, and respect. He decided to dedicate his life to helping them. He studied and learned about other leaders who fought for civil rights and justice, especially Martin Luther King Jr., who taught about non-violence – making change peacefully, without fighting.

In 1962, Cesar Chavez, along with Dolores Huerta, started a special group called the United Farm Workers (UFW). This was a union, a group of workers who joined together to have a stronger voice and ask for better conditions from their employers.

The Great Grape Boycott

One of the most powerful ways Cesar Chavez helped farmworkers was by organizing strikes and boycotts. A strike is when workers stop working to protest for better conditions. A boycott is when people stop buying a certain product to show their support for a cause.

In 1965, the UFW organized a famous grape strike and boycott. Cesar Chavez asked people all across America to stop buying grapes. He traveled to different cities, giving speeches and encouraging people to support the farmworkers. Many people listened and stopped buying grapes. This put a lot of pressure on the grape growers.

A Legacy of Justice

The grape boycott lasted for five long years, but it worked! Because of Cesar Chavez's leadership, the farmworkers' courage, and the support of people all over the country, many grape growers finally agreed to better pay and working conditions for their farmworkers.

Cesar Chavez showed that even ordinary people, when they come together peacefully, can bring about extraordinary change. He taught us the importance of justice and that everyone, no matter their job, deserves to be treated with dignity and fairness. He passed away in 1993, but his legacy continues to inspire people to fight for what is right.

Reading

Who Was Jacob Riis?

Jacob Riis was a famous reporter and photographer who lived a long time ago, from 1849 to 1914. He was born in Denmark, a country in Europe, and later moved to New York City in the United States when he was a young man.

Life in New York City

When Jacob Riis first came to New York City, he was very poor. He saw many other poor people living in terrible conditions. Many families, especially immigrants, lived in crowded and dirty buildings called tenements. These buildings often had no windows, no fresh air, and no running water. Sickness spread easily, and children often played in unsafe streets because there were no parks.

A Reporter with a Camera

Jacob Riis became a police reporter, which meant he wrote about crimes and problems in the city. He spent a lot of time in the poorest neighborhoods. He saw firsthand how difficult life was for the people there. But just writing about it wasn't enough. He wanted to show people what he saw.

This was a time before many people had cameras. Photography was a new and exciting way to capture images. Jacob Riis learned how to take pictures, even in the dark, dirty tenements. He used a special kind of flash to light up the dark rooms and alleys.

How the Other Half Lives

In 1890, Jacob Riis published a very famous book called How the Other Half Lives. This book was filled with his powerful photographs and vivid descriptions. It showed the world the poverty (being very poor) and hardship that many New Yorkers faced every day. The pictures were shocking, and they made many people feel sad and angry.

Making a Difference

Because of Jacob Riis's book and photographs, important people, like politicians and wealthy citizens, began to pay attention. They realized that something needed to change. Soon, new laws were made to improve living conditions in the tenements. Some of the worst buildings were torn down, and parks and schools were built in their place.

Jacob Riis became known as a social reformer. A reformer is someone who tries to make society better. He used his unique talents as a writer and photographer to bring about real change and help improve the lives of countless people who were struggling. He truly uncovered the truth and inspired others to make a better world.

Slide Deck

Fraction Face-Off! Who's Bigger?

How do we know which fraction is larger or smaller?
Let's find out!

Welcome students and get them ready to learn about comparing fractions! Start with an engaging question to pique their interest.

Today's Mission: Compare Fractions!

I Can...

  • Compare two fractions with different numerators and denominators (from 2, 3, 4, 5, 6, 8, 10, 12, 100).
  • Use the symbols <, >, and = to record my fraction comparisons.
  • Justify my comparisons by using area or length models.
  • Justify my comparisons by using benchmark fractions (0, 1/2, or 1 whole).
  • Justify my comparisons by finding a common numerator or common denominator.
  • Remember that I can only compare fractions if they refer to the same whole.

Introduce the learning objective clearly. These are our 'I Can' statements for today's lesson. Read them aloud with the students.

The Golden Rule of Fractions!

You can only compare fractions if they are talking about the same whole!

Imagine: Is 1/2 of a tiny cookie bigger than 1/4 of a giant cookie? Not necessarily! We need to compare parts of the same size thing.

Emphasize the 'same whole' concept. Give an example like comparing a slice from a small pizza to a slice from a large pizza – it wouldn't be fair!

Strategy 1: Picture Power! (Area & Length Models)

Sometimes the easiest way to compare fractions is to draw them!

  • Area Models: Think of pizzas or brownies! Divide a shape into equal parts.
  • Length Models: Think of a candy bar or a measuring tape! Divide a line into equal parts.

This strategy helps us visualize the different parts of the same whole.

I Do (Teacher Models): Draw 1/2 and 2/3 on the board using identical rectangles. 'I see that 1/2 covers less area than 2/3. So, 1/2 < 2/3.' Emphasize the clear, visual steps.
We Do (Guided Practice): 'Let's draw 3/4 and 1/4 together. Which is larger? How can we tell?' Guide students to recognize that 3 parts are more than 1 part of the same whole.

Strategy 2: Benchmark Buddies! (0, 1/2, 1 Whole)

Sometimes you don't need exact answers! You can use 'benchmark' fractions to help you compare.

  • Is the fraction closer to 0?
  • Is the fraction closer to 1/2?
  • Is the fraction closer to 1 whole?

This involves multiple steps: identifying the benchmark, comparing each fraction to it, and then comparing the fractions to each other.

I Do (Teacher Models): 'I need to compare 1/8 and 5/6. I know 1/2 is a good benchmark. 1/8 is much smaller than 1/2. 5/6 is much larger than 1/2, almost a whole. So, 1/8 < 5/6.' Talk through the thought process.
We Do (Guided Practice): 'Let's try comparing 2/10 and 3/4 using benchmarks. Is 2/10 closer to 0 or 1/2? Is 3/4 closer to 1/2 or 1 whole?' Guide students to use these reference points.

Strategy 3: Common Denominator Crew!

When fractions have different denominators, we can make them 'speak the same language'!

  • Step 1: Find a common denominator (a number both original denominators can multiply to).
  • Step 2: Change both fractions so they have the new common denominator (multiply the numerator and denominator by the same number).
  • Step 3: Compare the numerators (the top numbers)!

This strategy involves multiple steps to transform and compare fractions.

I Do (Teacher Models): 'Let's compare 1/3 and 2/5. I can't compare them directly. I need a common denominator. The least common multiple of 3 and 5 is 15. So, I'll change 1/3 to 5/15 and 2/5 to 6/15. Now I can see 5/15 < 6/15, so 1/3 < 2/5.' Detail each step clearly.
We Do (Guided Practice): 'Now let's compare 1/2 and 3/8. What's a common denominator? How do we change the fractions? Which numerator is larger?' Work through the steps with student input.

Strategy 4: Common Numerator Crew!

Sometimes, the numerators (top numbers) are the same!

  • Step 1: Notice that the numerators are identical.
  • Step 2: Look at the denominators.
  • Step 3: The fraction with the smaller denominator is actually larger! (Smaller slices but fewer cuts mean bigger pieces!)

This simple, multi-step rule helps us quickly compare when the top numbers are the same.

I Do (Teacher Models): 'I want to compare 3/4 and 3/10. The numerators are both 3. If I have 3 slices of a pie cut into 4 pieces, those slices are much bigger than 3 slices of a pie cut into 10 pieces. So, 3/4 > 3/10.' Emphasize that more pieces means smaller pieces.
We Do (Guided Practice): 'Let's compare 2/5 and 2/3. What do you notice about the numerators? Which denominator means bigger pieces?' Guide students to the conclusion that 2/3 is larger.

Ready, Set, Compare!

We have learned many ways to compare fractions!

  • Picture Power (Models)
  • Benchmark Buddies (0, 1/2, 1)
  • Common Denominator Crew
  • Common Numerator Crew

Now, let's practice putting these strategies to work!

Summarize the strategies and prepare students for practice. Remind them they can use any strategy that makes sense to them.
