Introduction to Inequalities – Understanding ‘>’ and ” means more, ‘<' means less – Defining inequalities – Inequalities show if one number is bigger or smaller than another – Inequalities around us – Prices, scores, and heights can show inequalities – Practice with real examples | Begin the lesson by explaining the symbols for greater than (>) and less than (<), ensuring students can identify which is which. Introduce the concept of inequalities as a comparison between two values, where one is either greater than, less than, or equal to the other. Provide relatable examples from everyday life, such as comparing prices when shopping, scores in games, or heights of classmates, to illustrate the concept of inequalities. Encourage students to think of their own examples and understand that inequalities are not just math problems but are present in many real-world situations. Conclude with practice problems where students identify and write inequalities based on given scenarios.

Understanding Inequality Symbols – Symbols: Greater Than (>) and Less Than (‘ means one number is bigger than another, like 5 > 3. – Symbols: Greater Than or Equal To (e) and Less Than or Equal To (d) – ‘e’ means a number is bigger or the same, like 5 e 5. – Choosing the Correct Inequality Symbol – Use clues from multiplication to decide which symbol fits. | This slide introduces students to the basic symbols of inequality. Explain that the symbols are used to compare two numbers or expressions. The greater than (>) and less than ( 18, so 4 x 5 > 3 x 6.

Multiplication Review: Mastering the Basics – Recap of multiplication facts – Quick review of times tables up to 10×10 – Multiply single-digit numbers – Practice multiplying numbers like 3×4, 7×8 – Two-digit multiplication intro – Learn to multiply numbers like 12×15 | This slide is aimed at refreshing students’ memory of multiplication facts, which is essential before they can tackle two-digit multiplication. Start with a quick review of the times tables, ensuring that students can recall them quickly and accurately. Then, move on to multiplying single-digit numbers, providing examples and allowing for practice time. Finally, introduce the concept of two-digit multiplication with a simple example, explaining the process step by step. Emphasize the importance of understanding single-digit multiplication as a foundation for learning more complex problems. Provide additional practice problems for homework to reinforce the day’s lesson.

Multiplication and Inequalities – Effects of multiplication on inequalities – Multiplying can increase or decrease values, affecting the inequality’s direction – Multiplying both sides of an inequality – When we multiply both sides by the same positive number, the inequality stays the same – Examples of inequalities with multiplication – 5 x > 20 means x could be any number greater than 4, as 5 times 4 equals 20 | This slide introduces students to the concept of inequalities in the context of multiplication. It’s crucial to explain that multiplication can change the value of an expression and thus affect the inequality. Emphasize that when we multiply both sides of an inequality by a positive number, the direction of the inequality does not change. However, if we multiply by a negative number, the inequality reverses. Provide clear examples to illustrate these concepts, such as using simple numbers that the students can easily work with. Encourage students to solve a few problems on their own to solidify their understanding.

Solving Inequality Problems with Multiplication – Steps to solve inequalities – Identify the inequality sign and apply inverse operations to isolate the variable. – Try practice problems – Use sample problems to apply the steps learned. – Learn to check solutions – Plug in the solution to ensure it makes the inequality true. | This slide is aimed at teaching fourth graders how to approach and solve inequalities involving multiplication. Start by explaining the steps to isolate the variable, such as undoing multiplication or division by using the inverse operation. Provide several practice problems for the students to work through, using the step-by-step method. Emphasize the importance of checking their solutions by substituting the variable back into the original inequality to verify that it makes the inequality true. Encourage students to ask questions if they’re unsure and remind them that practice is key to mastering this concept.

Class Activity: Inequality Challenge – Pair up and solve problems – Share solutions with the class – Discuss different approaches – How did others solve it? Any new methods? – Reflect on learning – What did we learn from this activity? | This activity is designed to encourage collaborative problem-solving and discussion among students. Start by pairing students up and handing out worksheets with inequality multiplication problems. Allow time for each pair to work through the problems together. After solving, each pair will present their solutions to the class, fostering a sense of community and shared learning. Follow up with a group discussion to explore the different methods used by students, highlighting various approaches to solving inequalities. Conclude the activity with a reflective session, asking students what they learned and how they can apply these strategies to future math problems. Possible activities: 1) Create a poster of their solutions, 2) Act out the inequality using props, 3) Write a short story involving the inequality, 4) Draw a comic strip showing how they solved the problem, 5) Use manipulatives to represent the inequality.

Wrapping Up: Inequalities with Multiplication – Review of inequality multiplication – Homework: Practice worksheet – Complete the provided worksheet to reinforce today’s lesson – Upcoming: Division inequalities – Next class will focus on inequalities involving division – Keep practicing multiplication! | As we conclude today’s lesson on inequalities with multiplication, it’s important to recap the key concepts to reinforce student understanding. The homework assignment is a worksheet that will provide additional practice on this topic, ensuring students are comfortable with the material. Looking ahead, we will explore how these concepts apply to division. Encourage students to continue practicing multiplication at home to build a strong foundation for understanding inequalities in different mathematical operations.
