Understanding Multiplication – Multiplication as repeated addition – It’s like adding the same number over and over! – Example: 3 x 4 – Same as 4 + 4 + 4. Three groups of four! – Multiplication speeds up counting – Instead of counting one by one, we can count quicker! | This slide introduces the concept of multiplication to third-grade students as a method of repeated addition, which is a foundational building block for understanding two-digit multiplication. Start by explaining that multiplication is a shortcut for adding the same number multiple times. Use the example 3 x 4 to show that it’s the same as adding the number 4 three times. Emphasize that multiplication helps us count faster than adding one by one. Encourage students to think of multiplication as groups of numbers, which will later help them grasp area models for larger numbers. Have them practice with simple examples and confirm their understanding by asking them to convert small multiplication problems into repeated addition.

Multiplying with Area Models – Break down larger numbers – Split 12 into 10 and 2 for easier multiplication – Example: 4 x 12 with area model – 4 groups of 12 can be shown as an area model – Visualize multiplication – Area models turn abstract numbers into visual blocks – Practice with different numbers | This slide introduces students to the concept of using area models for multiplication, which helps in visualizing and understanding the process. Start by explaining how to break down larger numbers into tens and ones to simplify multiplication.

Emphasize how area models help in breaking down a complex multiplication problem into smaller, more manageable parts, making it easier for third graders to understand and solve. During the practice activity, guide the students through an example, such as multiplying 13 by 5, and encourage them to build their own area models. Provide additional examples for students to work on individually or in groups, and be ready to assist any student who needs help.

Let’s Multiply: Using Area Models – Example: 3 x 24 using an area model – Visualize 3 groups of 24 in a rectangle divided into parts – Break down 24 into 20 and 4 – 20 is 2 tens and 4 is 4 ones, easier to multiply – Multiply 3 by 20 and 3 by 4 separately – 3 groups of 20 is 60, and 3 groups of 4 is 12 – Add the two products for the final answer – 60 (from 20s) plus 12 (from 4s) equals 72 | This slide introduces students to the concept of using area models for multiplication, which helps in visualizing the process. Start with an example like 3 x 24, and show how to break down the two-digit number into tens and ones. This simplifies the multiplication as students can easily multiply single-digit numbers. After calculating the separate products, guide students to add them together to find the final answer. Emphasize that this method is a systematic approach to handle larger numbers by breaking them into smaller, more manageable parts. Encourage students to practice with different numbers to gain confidence in this method.

Practice Time: Multiplying with Area Models – Let’s solve multiplication problems – Remember our multiplication tips – Break numbers into tens and ones, use a grid to multiply each part – Partner up: Multiply 5 x 32 – Use an area model to find the product of 5 and 32 – Share your area model with the class – Explain your model and how you got the answer | This slide is designed for a collaborative classroom activity where students practice multiplying one-digit numbers by two-digit numbers using area models. Begin by solving a few problems together as a class to demonstrate the process. Emphasize tips such as breaking down the two-digit number into tens and ones and using a grid to multiply each part separately. Then, have students pair up to solve the problem 5 x 32 using an area model. Encourage them to discuss their strategies with their partner and ensure they understand each step. Afterward, ask some pairs to share their area models and explain their thought process to the entire class. This activity will help solidify their understanding of multiplication and the use of area models. Provide guidance and support as needed, and prepare to offer additional examples if students require more practice.
