Today’s Adventure: Multiplying by 4!
– Multiplication as repeated addition
– Think of multiplication like adding a number over and over.
– Multiplying numbers by 4
– 4 times a number is like adding that number 4 times. Example: 4 x 3 is like 3 + 3 + 3 + 3.
– Why learn multiplication?
– It’s a quick way to add the same number many times!
– Practice problems
– Let’s try some together: 4 x 2, 4 x 5, 4 x 6.

This slide introduces the concept of multiplication as repeated addition, specifically focusing on multiplying by 4. Start by explaining that multiplication is a shortcut for adding the same number several times. Use simple examples to show how multiplying by 4 is like adding a number four times. Emphasize the importance of multiplication in making calculations quicker and easier. Conclude with some practice problems to solidify the concept, ensuring to provide different levels of difficulty to cater to all students. Encourage students to use objects like counters or draw pictures to visualize the multiplication process.
Understanding Multiplication: Groups of Four
– Multiplication: repeated addition
– It’s like adding 4 three times: 4 + 4 + 4
– Example: 4 times 3
– Instead of 4 + 4 + 4, we can say 4 times 3
– A quicker way to add
– Saves time compared to one-by-one addition
– Useful for equal groups
– Helps with items in equal sets, like 4 apples in 3 bags
|
This slide introduces the concept of multiplication as a method of adding the same number multiple times. Use the example of 4 times 3 to show how it’s like adding the number 4 together three times. Emphasize that multiplication is a shortcut for addition when dealing with groups of the same size. Encourage students to think of multiplication as a tool for dealing with equal groups, such as several packs of the same number of items. Provide additional examples and practice problems to reinforce the concept.
Let’s Multiply by 4!
– Multiplying makes groups of 4
– Example: 4 x 2 is 4 groups of 2
– Like having 4 baskets with 2 apples each
– Practice with pencils
– Arrange 8 pencils into 4 groups of 2
– Understanding multiplication
– It’s like adding the same number 4 times!
|
This slide is aimed at helping third-grade students understand the concept of multiplication as a form of repeated addition. Start by explaining that multiplying by 4 means creating 4 equal groups of a number. Use the example of 4 x 2 to illustrate this with a relatable scenario, such as having 4 baskets with 2 apples in each. For the class activity, have students use pencils to physically group items, which reinforces the concept through tactile learning. Encourage them to arrange 8 pencils into 4 groups of 2 to visualize the multiplication process. Emphasize that multiplication is a shortcut for adding the same number multiple times, which will help them grasp the concept more firmly. Prepare to guide them through the activity and answer any questions they may have.
Patterns in Multiplying by 4
– Spotting patterns with 4
– Each time, it’s like adding 4 more
– Writing the 4 times table
– Let’s list the multiples of 4 up to 40
– Patterns aid memory
– Recognizing patterns makes it easier to recall
– Practice multiplication facts
|
This slide is aimed at helping third graders identify and use patterns to multiply by 4. Start by asking students if they see any patterns when multiplying numbers by 4, such as how each product is 4 more than the previous one. Then, work together to write out the 4 times table, from 4×1 up to 4×10, and have them notice the pattern in the last digits of each product. Emphasize how recognizing these patterns can help them remember their multiplication facts more easily. Encourage the students to practice these patterns with different numbers and to use them as a strategy to master their multiplication tables.
Using Multiplication in Real Life: Multiply by 4
– Multiplication for quick math
– Example with apples and friends
– If each of 4 friends has 4 apples, in total there are 4 x 4 = 16 apples.
– Discuss other uses of multiplying by 4
– Think about groups of 4 in daily life, like 4 wheels on a car.
|
This slide aims to show students how multiplication is a handy tool for quick calculations in everyday situations. Start by explaining that multiplication is a faster way to add the same number several times. Use the example of 4 friends with 4 apples each to illustrate this concept with a relatable scenario. Then, engage the class in a discussion about where else they might encounter groups of 4 in their daily lives, such as in a pack of crayons, the legs on a table, or wheels on a car. Encourage them to think of other examples and understand that multiplication is not just a math skill but a practical tool they can use outside of the classroom.
Class Activity: Multiplication Art
– Create a 4-section art piece
– Show groups of 4 items in each
– Use stickers, drawings, or objects
– Be creative! Use colorful stickers, draw your favorite animals, or even use small toys.
– Share and explain your artwork
– Tell the class how your art represents ‘4 times something’.
|
This activity is designed to help students visualize the concept of multiplication by 4 through a creative and engaging art project. Each student will create an art piece divided into four sections, with each section containing four items. This could be four groups of stickers, four drawings of animals, or any other set of objects they choose. Encourage students to be imaginative with their representations. After completing their art, each student will share their work with the class and explain how it demonstrates multiplication by 4, reinforcing their understanding of the concept. Possible variations for different students could include using different mediums (paint, clay, digital tools), focusing on different themes (seasons, holidays, under the sea), or even incorporating storytelling into their art piece.
Game Time: ‘Four in a Row’
– Play ‘Four in a Row’ with a friend
– Roll a dice and multiply by 4
– If you roll a 3, what’s 3 times 4?
– Mark your answer on the board
– Find the product on the game board
– First to 4 in a row wins!
– Strategy and multiplication practice
|
This interactive game is designed to reinforce the concept of multiplying by 4. Students will pair up and take turns rolling a dice. They will then multiply the number rolled by 4 and mark the corresponding product on the game board. The goal is to get four correct answers in a row, either vertically, horizontally, or diagonally. This activity not only helps students practice their multiplication skills but also encourages strategic thinking. For the teacher: Prepare a game board with products of numbers 1 through 6 multiplied by 4, ensure each student understands the rules, and monitor the class to help with multiplication if needed. Have a few variations of the game ready for students who finish early or for those who need additional practice.
Multiplying by 4: Review and Practice
– Reviewing multiplication by 4
– Let’s recall the steps to multiply numbers by 4.
– Complete the worksheet
– Solve problems on the worksheet to show what you’ve learned.
– Ask for help if needed
– Don’t be shy, questions are welcome!
– Practice makes perfect!
|
This slide is aimed at reinforcing the students’ understanding of multiplication by 4. Begin with a quick review of the concept, perhaps by going over a few examples as a class. Distribute the multiplication by 4 worksheets and allow students time to complete them. Encourage them to raise their hands and ask for help if they encounter any difficulties. Emphasize that making mistakes is a part of learning and that practice is essential to mastering multiplication. As students work, walk around the classroom to offer individual support. Collect the worksheets at the end to assess their understanding and plan future lessons accordingly.
Homework Challenge: Mastering Multiplication by 4
– Practice 4 times table at home
– Teach family multiplication by 4
– Explain the pattern when you multiply numbers by 4
– Share a story using multiplication by 4
– Maybe you used it to count wheels on cars or legs on chairs!
– Bring your experience to class
|
This homework challenge is designed to reinforce the students’ understanding of the 4 times table through practice and teaching. Encourage students to find patterns and use them to remember the products. By teaching someone else, students will reinforce their own knowledge and gain confidence in their ability to multiply by 4. Ask them to observe where multiplication by 4 appears in their daily life, such as counting wheels on vehicles or legs on furniture, and to share these stories in class. This will help them see the practical application of what they learn and understand the relevance of multiplication in real-world scenarios.
