Multiplication Using Area Model Worksheets This video demonstrates how to create an area model in order to visualize and solve double digit multiplication problems. 1. draw an area model then solve using the standard algorithm. use arrows to match the partial products from the area model to the partial products in the algorithm. a. 24 × 21 = . 3. Identify, through investigation (e.g., by using sets of objects in arrays, by drawing area models), and use the distributive property of multiplication over addition to facilitate computation with whole numbers (e.g.,“. i know that 9 x 52 equals 9 x 50 9 x 2. this is easier to calculate in my head because i get 450 18 = 468.”).
Progression Of Multiplication Arrays Area Models Standard Algorithm So the product of 3 x 3,245 is 9,735. area model multiplication: 2 digit by 2 digit numbers. area model multiplication is also great when multiplying 2 digit by 2 digit numbers. again, it is important to break down both factors. let’s try it with an example. multiply 25 x 32. break down both factors so that they show tens and ones. The following figures give an example to compare multiplication using the area model, partial products, and the standard algorithm. scroll down the page for more examples and solutions. lesson 6 concept development compare the area model to the standard multiplication algorithm problem 1 64 × 73 problems 2–3 814 × 39 624 × 82. If you know how to multiply using area model, this video will show you how to transition to using the standard algorithm. Each group works to find the match of the multiplication problem and its area model. there will be at least 4 rounds. round 1: 2 digit by 1 digit – with graph paper and counting the squares. round 2: 3 digit by 1 digit – less than 130 x 1 digit (graph and count squares) round 3: 3 digit by 1 digit – modeled, with dimensions labeled (not.
