To find the product using rectangles when factoring tens, you can follow these steps:
1. Start by representing the first factor (the tens digit) as a rectangle. For example, if the tens digit is 4, draw a rectangle that has a length of 4 units and a width of 1 unit.
2. Next, represent the second factor (the ones digit) as a rectangle. Use the same length and width, 1 unit, to represent the ones digit. In this example, draw another rectangle with a length and width of 1 unit.
3. Now, position the two rectangles next to each other. The length of the resulting rectangle will represent the product.
4. Count the number of squares within the resultant rectangle to determine the answer. Each square represents one unit, so the total number of squares will be the product.
For example, if you want to find the product of 4 and 3, draw a rectangle with a length of 4 units and a width of 1 unit. Then, draw another rectangle with a length and width of 1 unit. Position them next to each other, and the resulting rectangle will have a length of 4 units and a width of 1 unit. Count the number of squares within this rectangle, which will be 12. Therefore, the product of 4 and 3 is 12.
