![]() ![]() Then show the students how to draw area models on graph paper. So we can think of this as 3×10 = 30 plus 3 rows of 2, 3×2= 6 Place a piece of tape at the 10 inch mark on each ruler.Įxplain how multiplication can be made easier if we split larger numbers into place value. Then ask if there’s a way to split 12 into place value. Tell the students that you have 3 rows of 12 inches. Stack the rulers to show that it is 2 rulers of 12 inches each. Then hold up 2 rulers, and ask how many inches. Ask the class how many inches long it is. Launch the Multiplying Multi-digit Numbers using Area Models Activity ![]() Worksheet : Multiplying 3 and 4 digit numbers using Area Models (one copy for each student).Set up for the Multiplying 3 and 4 digit Numbers using Area Models Activity So find some tiles on the floor and grab some graph paper – it is time to teach multiplication by using AREA and place value–and students even get to color! So if fourth graders can learn ways to see multiplication with area, they can build an understanding that will help them when they use the distributive property and when they explore factors and multiples.ĪREA is an ARRAY of squares. Area models can also be used when students start learning algebra and factoring equations. Area is a geometry skill but it is also a visual way to look at multiplication. It’s a great way to use multiplication and find the missing sides and dimensions. ![]() I also like to use Area puzzles with my students. But students soon start to see equal rows of tiles and they figure out ways to use multiplication too! One way to find the area is to count each tile. We step on the tiles and see how the squares make up the area. I like to bring my class up to the hallway and give them an area to calculate. We have tiles on the floors of the hallways at school. It can also be used for real life applications. Being able to see the area is just like making rows or groups of numbers. Students learn arrays and see groups of numbers. In this activity we will be Multiplying 3 and 4 digit Numbers using Area Models.Īrea is a great way to show how multiplication works. This can help students learn and understand multiplication as well as apply it to the standard algorithm for multiplication. Multiplying multi-digit numbers using area not only helps students to visualize the products, but also helps show them how partial products work and add up.
