Understanding the standard algorithm for multiplication
The standard algorithm for multiplying whole numbers involves breaking the numbers down into their place values and multiplying each place value separately. This process is illustrated through three examples: one complete walkthrough, one where the viewer is asked to identify mistakes in incorrect solutions, and one where the viewer is asked to ...

Finally, something you remember! 🥳 ➡️ As the numbers we multiply get bigger, the standard algorithm becomes more appealing (and necessary) for our kids. 🌟 When we were in elementary, you might have known the steps to multiply, but didn’t think about WHY they worked. Now, try comparing the standard algorithm with the partial products method. I feel like the standard algorithm is a squished version of the partial products method. 💡 If your student is struggling with the standard algorithm, try
