Today’s Adventure: Multiplying by Multiples of Ten! – Grasp the basics of multiplication – Multiplication is adding a number to itself several times – Explore why ten is special – Multiplying by 10 ends with a zero, making it easy! – Practice multiplying numbers by 10 – Try 5 x 10 and see the number grows bigger quickly! – Discover patterns with multiples of 10 – Notice how the digits shift place when you multiply by 10 | This slide introduces third graders to the concept of multiplication with a focus on multiples of ten. Begin by explaining multiplication as repeated addition. Emphasize the simplicity and patterns that emerge when multiplying by ten, such as the resulting number always ending in zero. Engage the students with examples and encourage them to observe what happens to the digits in a number when we multiply by 10. For instance, 3 becomes 30, 7 becomes 70, showing a pattern of place value shifting. This understanding will help them grasp larger multiplication concepts and prepare them for more complex problems. Provide ample practice problems and use visual aids like number lines or place value charts if possible.

Understanding Multiplication – Multiplication: Repeated addition – Example: 3 x 4 equals 4 added 3 times – Like 4+4+4, which equals 12 – Visual groups to show multiplication – Picture 3 groups of 4 apples to help understand – Practice with multiples of ten – Try 10 x 3 with ten groups of 3 objects | This slide introduces the concept of multiplication to third graders by relating it to repeated addition, a concept they are familiar with. Start by explaining that multiplication is a shortcut for adding the same number multiple times. Use the example of 3 x 4 to show that instead of adding 4 three times, we can simply multiply 3 by 4 to get 12. To visually reinforce this concept, use objects like apples or blocks to create groups that represent the multiplication. This will help students visualize the process. Finally, apply this understanding to multiplying by multiples of ten, which is a foundational skill for two-digit multiplication. Encourage students to practice with different multiples of ten to gain confidence.

Multiplying by Multiples of Ten – Understanding multiples of ten – Multiples of ten: 10, 20, 30, … – Patterns in multiplying by tens – Notice how the zero at the end stays the same – Group items by tens activity – Use objects to make groups of 10 – Practice with real examples – Multiply numbers like 5 x 20 or 3 x 40 | This slide introduces the concept of multiples of ten and how to recognize patterns when multiplying by tens. Start by explaining what multiples of ten are, using examples like 10, 20, 30, and so on. Highlight the pattern that the number of zeros increases as we multiply by higher multiples of ten. For the hands-on activity, provide students with small objects to group in sets of ten, reinforcing the concept of grouping and multiplication. Finally, give real-world examples such as ‘If you have 5 packs of stickers and each pack has 20 stickers, how many stickers do you have in total?’ to apply their understanding of multiplication by tens. The goal is to make students comfortable with the idea of scaling numbers by ten and its multiples.

Multiplying by Ten: The Magic of Zero – Understanding multiplying by 10 – Adding a zero to the number – When we multiply any number by 10, we add a zero at the end of the number. – Example: 3 x 10 equals 30 – Multiplying 3 by 10, we just add a zero to 3, making it 30. – Practice multiplication together – We’ll solve some problems as a class to learn this trick! | This slide introduces the concept of multiplying by ten, emphasizing the pattern that emerges when a single-digit number is multiplied by 10. The key takeaway for students is the ‘magic of zero’ the idea that multiplying by ten adds a zero to the end of the number. Start with the example provided (3 x 10 = 30) to illustrate this concept. Then, engage the class with a few practice problems, encouraging them to apply this rule. As you work through the examples, ensure that students understand this is a specific case of multiplication by ten and not a general rule for all multiplication. The activity will help solidify their understanding and prepare them for more complex multiplication.

Multiplying by Multiples of Ten – Understand tens and multiplication – Example: Multiply 4 x 20 – Think of it as 4 x 2, then add a zero to the result – Group activity with a partner – Work together to solve multiplication problems – Practice and share answers – Discuss solutions and methods used | This slide introduces the concept of multiplying by multiples of ten, building on the students’ existing knowledge of tens. Start by reviewing what they know about multiplication and the significance of the number ten. Use the example 4 x 20 to illustrate the process: first multiply 4 x 2 to get 8, then add a zero to make it 80, which is the same as 4 x 20. For the group activity, pair students up and provide them with a set of problems involving multiplication by multiples of ten. Encourage them to use the method demonstrated in the example. After the activity, have each pair share their answers and discuss the strategies they used. This will help reinforce the concept and allow students to learn from each other.

Begin with examples on the board, encouraging students to participate in solving them. Move on to guided practice where you, as the teacher, provide support and step-by-step instructions. Foster an environment of collaboration by having students discuss their thought processes and solutions with peers. Finally, set up group problem-solving activities to reinforce the concept. Possible activities include using manipulatives, drawing models, or creating word problems that involve multiplication by tens. Assess understanding through observation and by asking students to explain their reasoning.

Multiplying by Tens in Real Life – Understanding multiplication by tens – Example: Buying sticker packs – If one pack costs $10, what’s the cost of 5 packs? – Discuss everyday applications – Where have you used multiplication by tens? – Practice with real examples – Use examples like money and time for practice | This slide aims to show students how multiplication by tens is used in everyday scenarios, reinforcing the concept with tangible examples. Start by explaining the basic idea of multiplying by tens. For instance, if one sticker pack costs $10, then buying 5 packs would cost 5 times 10, which equals $50. Encourage students to think of and discuss other situations where they might use this type of multiplication, such as calculating the total cost of multiple movie tickets or the total minutes in several hours. Provide additional examples and have students practice with these real-world applications to solidify their understanding.

Class Activity: Multiplication Art! – Create multiplication-themed art – Use arrays for tens multiplication – Arrays help visualize multiplying by 10, like 10×3 shown as 3 rows of 10 dots – Share your art with the class – Explain your multiplication process – Describe how you used arrays in your artwork to show multiplication | This activity is designed to combine creativity with mathematical understanding. Students will create their own art pieces that incorporate arrays to represent multiplication by tens. For example, they can draw or use stickers to create rows and columns that match multiplication problems (e.g., 10×3 as 3 rows of 10). After completing their artwork, students will present their art to the class and explain how the arrays in their art demonstrate the multiplication by tens. This will help them understand the concept of multiplication as repeated addition and how it relates to the base-ten system. Possible activities: drawing, using stickers, stamping, or arranging objects. Encourage students to be creative and ensure they understand the multiplication concept behind their art.
