Welcome to Multiplication! – Today’s focus: Facts up to 10 – Multiplication as groups – Think of multiplication as adding groups of the same number. For example, 3 groups of 4 is 3×4. – Why it’s a super skill – It helps us count faster and solve problems quickly! – Practice makes perfect – The more we practice, the quicker we’ll remember our facts! | This slide introduces third graders to the concept of multiplication, emphasizing its importance and utility in everyday math. Start by explaining that multiplication is a way to add the same number several times, which is faster than adding one by one. Highlight how multiplication is used in various aspects of life and why it’s considered a ‘super skill’ in math. Encourage students to see multiplication as a tool that makes counting large quantities easier and more efficient. To reinforce learning, suggest that students practice multiplication facts regularly, as this will help them memorize and recall these facts quickly. Incorporate interactive activities and games to make the learning process enjoyable and engaging.

Understanding Multiplication – Multiplication: Repeated addition – It’s like adding the same number many times! – Example: 3 x 4 with apples – Imagine adding 4 apples to your basket 3 times. – Multiplication speeds up addition – Instead of adding 4 + 4 + 4, we can just multiply 3 x 4! | This slide introduces the concept of multiplication as a method of repeated addition, which is a foundational skill in third-grade mathematics. 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 it’s the same as adding 4 apples to a basket 3 separate times, which helps visualize the concept. Emphasize that multiplication is a faster way to do repeated addition, making it very useful for solving problems quickly. Encourage students to think of their own examples of repeated addition that could be solved with multiplication.

Mastering Multiplication Facts – Memorization makes math simpler – Explore the multiplication chart – A visual tool that helps us see the products of numbers up to 10. – Recognize patterns in facts – Patterns like repeated addition can make multiplication easier to understand. – Focus on 5s and 10s patterns – Numbers ending in 0 or 5 have a pattern that makes them easier to memorize. | This slide aims to emphasize the importance of memorizing multiplication facts to ease future math challenges. Introduce the multiplication chart as a visual aid to help students see the relationship between numbers. Highlight the significance of recognizing patterns, such as those in the 5s and 10s, which can be easier to remember due to their consistency. Encourage students to look for and use these patterns as a strategy to quickly recall multiplication facts. During the presentation, walk through the chart with the class, pointing out these patterns and how they repeat. This will help solidify their understanding and recall of multiplication facts.

Finding the Missing Factor in Multiplication – Multiplication facts: two factors and a product – Discover the missing factor When one factor is unknown, we play detective to find it! – Example: 4 x ? = 20 To find the missing number, think: 4 times what equals 20? – Solving for the unknown factor Divide the product by the known factor to find the missing one. | This slide introduces the concept of finding a missing factor in a multiplication equation. Emphasize that every multiplication fact consists of two factors that multiply to give a product. When one of these factors is missing, students must use their understanding of multiplication facts up to 10 to find the missing number. Use the example provided to illustrate the process: if 4 times a number equals 20, what is that number? Guide students to understand that they can find the missing factor by dividing the product (20) by the known factor (4). This will give them the missing factor, which is 5 in this case. Encourage students to practice with different multiplication facts and to share their strategies for finding the missing factor.

Let’s Practice Multiplication! – I’ll show a problem with a missing number – We’ll solve the first ones as a team – Think: What number times another equals the answer? – If 4 x ? = 20, what number works for ‘?’? – Practice makes perfect in multiplication! | This slide is designed to engage the class in a collaborative problem-solving activity focused on multiplication. Display a multiplication problem with one factor missing, and guide the class through the process of finding the missing number. Encourage students to use their knowledge of multiplication facts up to 10 to deduce the missing factor. For example, if the problem is 4 x ? = 20, prompt them to think about which number, when multiplied by 4, results in 20. This exercise will help reinforce their understanding of multiplication and improve their fluency. Make sure to praise their efforts and remind them that practice is key to mastering multiplication facts.

Your Turn: Finding Missing Factors – Try solving multiplication problems – Use your multiplication chart for help – A chart with all the products of numbers 1-10 – Practice leads to perfection – The more you practice, the better you’ll get! – Share your answers with the class – Discuss how you found the missing factor | This slide is an activity prompt for students to practice finding missing factors in multiplication problems. Encourage them to use their multiplication charts as a reference tool to help them find the answers. Remind them that practicing these problems will help them become more fluent in multiplication. After they have attempted the problems, ask them to share their answers and the strategies they used to find the missing factors with the class. This will help reinforce their learning and allow them to learn from each other. Possible activities include: 1) Multiplication bingo, 2) Partner quizzes, 3) Timed multiplication races, 4) Creating their own multiplication problems for peers, 5) Using manipulatives to visualize the multiplication process.

Class Activity: Multiplication Bingo – Play Bingo with multiplication facts – Find the missing factor to mark the spot – Example: For 3 x ? = 9, the missing factor is 3 – Five in a row wins a prize! – Enhance multiplication fluency – Practice makes perfect with fun! | This interactive class activity is designed to help students practice and reinforce their multiplication skills in a fun and engaging way. Set up the Bingo game by creating cards with multiplication problems missing one factor. As you call out the products, students will solve for the missing factor and mark their cards accordingly. The first student to get five correct answers in a row horizontally, vertically, or diagonally wins a prize. Make sure to have small rewards ready to motivate the students. Rotate through different sets of problems to give all students a chance to win and to cover a range of multiplication facts. This activity not only helps with memorization of multiplication facts but also with quick mental calculations, enhancing overall fluency.

Wrapping Up: Missing Factors – Congratulations on learning missing factors! – Practice with your multiplication chart – Use the chart to help find factors quickly – Homework: Missing Factor worksheet – Complete the worksheet to test your skills – Keep practicing for mastery! | Well done on today’s lesson about finding missing factors in multiplication! Remember, understanding multiplication is like learning to play a sport or an instrument – it takes practice. Use your multiplication chart to help you find the missing factors faster. For homework, you have a worksheet that will help you practice what you’ve learned. Try to solve the problems without the chart first, but if you get stuck, use the chart to help you out. Keep practicing, and you’ll become a multiplication master in no time!
