Today’s Adventure: Multiplying by 1! – Multiplication as repeated addition – If you have 4 groups of 1 apple, you have 4 apples. – Multiplying any number by 1 – 5 x 1 = 5. The number stays the same! – The identity property of 1 – Multiplying by 1 doesn’t change the value. – Practice with real examples – Let’s try 7 x 1 and 1 x 9 together! | This slide introduces the concept of multiplication as repeated addition, which is a foundational skill in mathematics for third graders. Emphasize that when we multiply any number by 1, the result is the original number itself, demonstrating the identity property of multiplication. This property states that any number multiplied by 1 equals the number itself. Provide students with simple, relatable examples to practice, such as multiplying their age by 1 or the number of pets they have by 1. Encourage them to understand that the number doesn’t change, reinforcing the concept that 1 is the multiplicative identity. This will set the stage for understanding more complex multiplication in the future.

Understanding Multiplication: Multiply by 1 – Multiplication as repeated addition – It’s like adding the same number many times – Example: 3 x 1 equals 1 + 1 + 1 – Instead of adding 1 three times, we multiply 3 by 1 – Multiplication speeds up adding – It’s a shortcut for addition when using the same number | This slide introduces the concept of multiplication as a form of repeated addition, which is a foundational skill in mathematics. By understanding that 3 x 1 is the same as adding 1 three times, students can grasp the concept of multiplication as a quicker way to add the same number multiple times. Emphasize that multiplying by 1 is a simple introduction to multiplication, as any number multiplied by 1 remains unchanged. This reinforces the identity property of multiplication. Encourage students to think of multiplication as a faster method of addition to help them transition to more complex multiplication problems.

The Magic of Multiplying by 1 – Multiplying by 1 keeps numbers same – 1 x any number mirrors the number – Like looking in a mirror, 1 x 5 reflects back 5 – No change when you multiply by 1 – Practice: Multiply different numbers by 1 – Try it out! 1 x 3? 1 x 7? What do you notice? | This slide introduces the concept that multiplying any number by 1 results in the same number, a fundamental property in multiplication. It’s crucial for students to understand that 1 acts as the multiplicative identity, meaning it does not alter the value of the other number. Use examples to demonstrate this concept, such as 1 x 5 equals 5, and encourage students to think of the number 1 as a mirror reflecting the other number. To reinforce this concept, have students practice with various numbers, multiplying them by 1 and observing that the product remains unchanged. This will help solidify their understanding of multiplication by 1 as they build their multiplication skills.

Let’s Practice Multiplying by 1! – Example 1: 1 x 6 equals what? – It’s like a mirror! 1 x 6 shows 6. – Example 2: 8 x 1 equals what? – Just like a mirror, 8 x 1 reflects 8. – Discuss: Multiplying by 1 effect – Turn and talk activity – Share why 1 keeps the number same. | This slide is designed for a class activity to reinforce the concept that multiplying any number by 1 results in the same number. Start with two examples, asking students to solve them. Emphasize the mirror analogy to help them remember that multiplying by 1 reflects the same number back. After the examples, engage the class in a ‘turn and talk’ activity where they discuss with a partner why multiplying by 1 always gives us the same number. This encourages critical thinking and helps solidify their understanding. For the teacher: Be prepared to facilitate the discussion and provide guidance. Possible activities include pairing students to solve more multiplication by 1 problems, using manipulatives to visually demonstrate the concept, or creating a class chart with the ‘mirror rule’ for multiplying by 1.

Multiplication Patterns with Number 1 – Multiplying any number by 1 – The answer is always the same number – Fill in the blanks: __ x 1 = __ – Let’s try together: 5 x 1 = ?, 8 x 1 = ? – Patterns make multiplication easy – Recognizing patterns helps us solve problems faster – Practice helps us remember! | This slide introduces the concept that any number multiplied by 1 remains unchanged, which is a fundamental property of multiplication. Encourage the students to observe this pattern by trying out different numbers multiplied by 1. Use the fill-in-the-blank exercise to make the learning interactive. Explain that understanding this pattern is crucial as it lays the groundwork for more complex multiplication. During the class, have students come up to the board to fill in the blanks, and then discuss as a class why the pattern occurs. Provide plenty of examples and encourage students to practice with their own numbers to reinforce the concept.

Multiplication Games: ‘Mirror, Mirror on the Wall’ – Pair up for a flashcard quiz – Challenge: Multiply by 1 – Every number times 1 stays the same – Spot the pattern quickly – Look for numbers that don’t change – Share the pattern you find – Explain the pattern to your partner | This slide introduces a fun and interactive game to help students practice multiplication by 1. The game ‘Mirror, Mirror on the Wall’ involves students pairing up and using flashcards to quiz each other. The objective is to reinforce the concept that any number multiplied by 1 remains unchanged, which is a fundamental multiplication rule. Encourage students to be quick in recognizing this pattern. After the activity, ask them to share their findings with the class to ensure they understand the concept. For the teacher: Prepare flashcards with different multiplication by 1 equations. Monitor the pairs to ensure they are engaged and understanding the pattern. Offer praise and gentle corrections as needed.

Class Activity: Multiplication Art – Create a ‘Multiply by 1’ art piece – Draw objects with multiplication facts – For example, draw 1 sun and write ‘1 x 1 = 1’ – Share your art with the class – Explain your learning about multiplying by 1 – Tell us why any number times 1 equals the number itself | This activity is designed to reinforce the concept that any number multiplied by 1 remains unchanged. Students will express their understanding creatively by drawing and incorporating multiplication facts into their artwork. Encourage them to be imaginative with their drawings, using items they’re familiar with, such as 1 tree, 1 cat, etc. After completing their art, students will present their work to the class, explaining the multiplication by 1 concept. This will help solidify their understanding and improve their communication skills. Possible variations of the activity could include group work, using different art materials, or creating a classroom display with the completed art pieces.

Great Work on Multiplying by 1! – Multiplying any number by 1 – The product is the same number – Homework: ‘Multiplication by 1’ worksheet – Complete the provided worksheet to practice. – Practice makes perfect! – Keep practicing to master multiplication by 1. | This slide is a conclusion to the lesson on multiplying by 1. It serves as a reminder that when any number is multiplied by 1, the product is the number itself. The homework assignment is to complete the ‘Multiplication by 1’ worksheet, which will provide students with additional practice to reinforce the concept learned. Encourage students to try their best and remind them that practicing these problems will help them become more confident in their multiplication skills.
