This slide introduces third graders to the concept of multiplication, specifically focusing on the number 7. Start by explaining multiplication as a form of repeated addition, which is a more familiar concept at this grade level. Emphasize the practicality of knowing how to multiply by 7, such as understanding weeks in terms of days. Include practice problems to solidify their understanding, and engage them with interesting facts about the number 7 to make the lesson more memorable. Encourage students to think of other instances where the number 7 comes up in their daily lives.
Multiplying by 7: Quick Addition!
– Multiplication: Repeated addition
– Example: 7 x 3 equals 7 + 7 + 7
– Instead of adding 7 three times, we multiply 7 by 3
– A shortcut for adding quickly
– Practice with the number 7
– Let’s try some examples together: 7 x 2, 7 x 4, 7 x 5
|
This slide introduces the concept of multiplication as a method of adding the same number repeatedly, which is a key concept for third graders learning to multiply. Start by explaining that multiplication is a shortcut for adding the same number over and over again. Use the example of 7 x 3 to show how it’s the same as adding 7 three times. Emphasize that this method is much faster than addition when dealing with larger numbers. Encourage the students to practice multiplying by 7 with different numbers to reinforce the concept. Provide additional examples and have the students solve them to ensure understanding.
The Magic of Multiplying by 7
– Discovering 7’s patterns
– 7 has unique patterns in multiplication
– Multiplying with magic number 7
– Let’s explore how 7 multiplies with other numbers
– Finger tricks for 7 times table
– Learn a cool finger trick to remember 7’s multiples
|
This slide is designed to engage third-grade students with the concept of multiplication by 7. Start by discussing the interesting patterns that emerge when multiplying numbers by 7, such as the fact that the tens digit goes up by one and the ones digit goes down by three each time (e.g., 14, 21, 28, 35…). Introduce the concept of multiplication as repeated addition and show how multiplying by 7 builds upon this idea. Demonstrate a finger trick to help students memorize the 7 times table, such as laying down the seventh finger and counting the fingers before and after it to get the product (e.g., for 7×3, lay down the third finger and count: 1, 2 on the left and 1, 2, 3, 4 on the right, making 21). Leave the fourth bullet point empty as the previous points cover the necessary content. The notes should provide detailed guidance for the teacher on how to present these concepts in a fun and interactive way, ensuring that the students can find patterns and use tricks to help them remember their 7 times table.
Multiplying by 7
– Learn the 7 times table
– We’ll memorize the table of 7 together
– Sing songs to remember
– Music makes it easier to remember numbers
– Practice multiplication
– Let’s solve multiplication problems as a class
– 1 x 7 = 7, 2 x 7 = 14, …
– Repeat after me and try some on your own

This slide is aimed at helping third-grade students learn and memorize the 7 times table. Introduce the concept with enthusiasm to engage the students. Use catchy songs and rhymes as they are effective mnemonic devices for young learners. Start with simple multiplication facts and gradually move to more complex ones. Encourage the students to practice aloud with you, reinforcing their learning through repetition. Provide ample opportunities for the students to practice, both with guidance and independently, to build their confidence and proficiency in multiplying by 7.
Using Multiplication by 7 in Daily Life
– Multiplication in everyday life
– 7 days in a week example
– A week has 7 days, so how many in 4 weeks?
– Calculate days in 4 weeks
– Multiply 4 weeks by 7 days to find out
– Solving multiplication together
– Let’s do it as a class: 4 x 7 equals?
|
This slide aims to show students the practical application of multiplying by 7 through a relatable example. Start by discussing how multiplication is not just a math concept but a useful tool in everyday life. Use the example of weeks and days to illustrate this point. Ask the students how many days are in one week (7 days) and then extend this to 4 weeks. Guide them through the process of multiplying 4 (weeks) by 7 (days in a week) to find the total number of days. Encourage the students to participate in solving the problem as a class activity. This will help them understand the concept of multiplication by 7 and its usefulness in real-life scenarios.
Group Activity: Multiplication Bingo
– Play Bingo with 7 times table
– Listen for products of 7
– Mark the product on your Bingo card
– Aim for five in a row to win!
|
This interactive group activity is designed to help students practice and reinforce their multiplication skills, specifically focusing on multiplying by 7. Prepare Bingo cards in advance with products of the number 7 randomly placed on the cards. Call out multiplication facts (e.g., 7×3, 7×5) and have students compute the product and then mark the corresponding number on their Bingo cards. The first student to align five products horizontally, vertically, or diagonally wins the game. To accommodate different learning paces, consider having multiple winners or playing several rounds. This activity not only makes learning multiplication facts fun but also encourages quick mental calculations and attentiveness.
Multiplication Practice: Times 7
– Time to practice multiplying by 7
– Complete the worksheet provided
– Worksheet has a variety of problems to solve
– Recall patterns and tricks for x7
– Like 7s in the ones place go 7, 4, 1, 8, 5, 2, 9, 6, 3, 0
– Show your work for each problem
– Use multiplication tricks to check your answers
|
This slide is designed to transition students from guided learning to independent practice. Provide a worksheet with a range of multiplication problems involving the number 7. Remind students to use the patterns and tricks discussed in class, such as the sequence of the ones digit in multiples of 7 or doubling and adding. Encourage students to work through each problem and show their steps. This will help reinforce their understanding and give them confidence in their ability to multiply by 7. As they work, circulate the room to offer support and answer questions. Collect the worksheets at the end for assessment.
Class Activity: Multiplication Relay
– Engage in a multiplication relay
– Work in teams to solve problems
– Multiply numbers by 7
– For example, 7 x 3 = ?
– Each correct answer advances your team
|
This activity is designed to make learning multiplication by 7 interactive and fun. Divide the class into small teams. Set up a relay course in the classroom or outside. Each team will solve a multiplication by 7 problem. When a team member gets the answer correct, they pass the baton to the next member or move to the next station. This continues until all team members have completed their turn. The first team to finish with all correct answers wins. Possible variations of the activity: 1) Use flashcards, 2) Incorporate physical activities like jumping jacks with each correct answer, 3) Have a ‘challenge’ station where they solve a word problem involving multiplication by 7, 4) Include a ‘creative’ station where they draw a representation of their multiplication fact, 5) Use a timer to add a sense of urgency. Remember to encourage teamwork and celebrate correct answers to foster a positive learning environment.
