How can you use 4s facts to find 7x8 for a 3rd grader to understand
UMM I WANT TO KNOW HOW
Not sure what you mean by "4s facts".
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
7 * 2 * 4 = 14 * 4?
Just tell me the answer
omg
To use the "4s facts" to find the product of 7 and 8 (7x8), we can break down the problem into smaller, more manageable parts. Here's how you can explain it to a 3rd grader:
1. Start by reminding the student of what they know about the "4s facts." In this case, we're talking about multiplication facts that involve the number 4. For example: 4x1=4, 4x2=8, 4x3=12, and so on.
2. Since we're trying to find 7x8, we can use the knowledge of the "4s facts" to help us. Ask the student to think about which "4s fact" is closest to the number 7. They should recognize that 4x2=8 is the closest because 2 is the largest number that we can multiply by 4 and still get a number smaller than 7.
3. Explain to the student that if 4x2 equals 8, then doubling that product will give us the answer to 7x8. Doubling means adding the same number to itself. In this case, we need to double 8. So, ask the student what is 8 + 8.
4. Help the student see that 8 + 8 equals 16. Thus, the answer to 7x8 is 16.
By using the "4s facts" to find the closest multiplication fact to one of the numbers being multiplied and then using addition (in this case, doubling) to reach the final answer, we can break down multiplication problems into simpler components that are easier for a 3rd grader to understand.
