Background – Agricultural Connections (what would a teacher need to know to be able to teach this content)
Iowa is the country’s largest corn producer, and it plays an important role in Iowa’s economy. Most of the corn grown in Iowa is dent corn, also called field corn. It is planted in the spring and harvested in the fall. Field corn is fed to animals, made into ethanol, and used to make foods like corn chips, cereal, corn bread, and candy.
Interest Approach or Motivator
Show the students the cover of My Family’s Corn Farm and ask them what they think the book is going to be about based on the cover. Continue the conversation by asking:
- Do you know any farmers who grow corn?
- What do you know about corn and farming?
- What would you like to know about corn and farming?
Activity 1: Topics–Main Ideas–Details (45 minutes)
- Ask students to read My Family’s Corn Farm independently using printed copies or the digital version.
- After reading ask, “What was the book about?”
- Students may say corn or Presley’s corn farm.
- Corn is the overall topic of the book, but there are many subtopics and key ideas within it.
- Next, ask them for more specific things they learned while reading the book? Develop a list on the board.
- Work with the class to determine subtopics within the book.
- Encourage them to look for themes or categories in the list of what they learned, and also flip through the book to help identify topics or themes. Examples of subtopics may include how corn grows, uses of corn, farm equipment, etc.
- Review the differences between topics, main ideas, and details.
- A main idea is more than a topic. To understand the main idea, you’ll first need to know what the text is about (topic), and then be able to explain the “so what?” or what about it. The “So what?” explains why it is important. Details are specific facts found in the book that support the main ideas.
- Distribute the Topics-Key Ideas-Details sheet and show an example of how they can use it determine the main ideas.
- Topic (What?): Uses of Corn
- Main Ideas (So what?): Corn is important because it can be used for many things.
- Details (Facts):
- Corn is fed to pigs, cattle, chickens, and turkeys.
- Corn is used to make ethanol.
- Corn is used to make food and other things we use every day.
- There are more than 4,000 uses for corn.
Ask students to use the Topics-Main Ideas-Details sheet to help determine two or three main ideas within the story. This can be done independently or in pairs.
Activity 2: TIP Method (10 minutes)
- Place a corn vocabulary card on each student’s desk, definition side down. You can make multiple copies of the set or have students work in pairs.
- Ask them not to look at the back of the card.
- Give each student a TIP Method worksheet, or write the letters T.I.P down the side of notebook or science journal page.
- Ask them to think about what the word means and how it was used in the book My Family’s Corn Farm.
- Some of the words, like combine or feed, have more than one meaning. Encourage them to think about how the word was used in the book and how it relates to corn.
- If students are unsure of their word’s meaning, have them reference the book and use context clues from the text and pictures to help. The vocabulary section of this lesson includes the page or pages that will be most helpful in determine the meaning of each word. Tell them not to look at the definition in the book’s glossary.
- To help them remember the meaning of the word, ask them to complete the TIP method worksheet by writing the word (Term), writing down as much information as they know about the word (Information), and drawing a picture that represents the word (Picture).
Activity 3: Corny Charades (20 minutes)
- Divide the class into groups of two or three.
- Give each group a corn vocabulary card that they will need to act out.
- Allow groups a few minutes to plan how they will act out the word.
- Choose a group to act out their word in front of the class. Remind them that they can’t use any words, the can only act.
- Other groups may try to guess the word that is being acted out.
- The first group to guess the correct word sores a point.
- To make the game more challenging, deduct a point for an incorrect guess. This will discourage groups from shouting random words from the book.
