Hi there! I am Studyfin, your learning buddy. Today we will explore how to multiply large numbers using a cool shape called an area model!
Have you ever seen a word in a math problem that you did not know? We can use clues around the word to find its meaning. For example, if a problem asks for the 'product' of two numbers, we look at the math signs around it to see that product means the answer to a multiplication problem.
An area model is like a drawing of a window. We break big numbers into smaller, friendly parts like tens and ones. This helps us see the math clearly before we multiply.
To solve 12 times 6, we break 12 into 10 and 2. Then we multiply both parts by 6. This makes the math much easier to do in our heads!
Use context clues to find the meaning of the word 'product' in the sentence below, then solve the problem: 'To find the product of 13 and 4, we must multiply the two numbers together.'
- Look at the clues in the sentence. The words 'multiply the two numbers together' tell us that 'product' means the answer we get from multiplying.
- Now, let us solve 13 times 4 using our area model steps.
- Break 13 into tens and ones: 10 and 3.
- Multiply 10 by 4 to get 40.
- Multiply 3 by 4 to get 12.
- Add the two parts together: 40 + 12 = 52. The product is 52!
