In this video, we return to bar models to see how they can be used to solve problems with more than one step. To solve <i>one-step</i> real-world measurement problems, you can watch videos 3-10!
In this video, I use addition and a part-part-whole bar model to solve the first step. I use subtraction and a part-part-whole bar model to solve the final step.
The problem in this video requires a multiplication bar model for the first part, and a compare bar model (with addition) for the second part.
What's our first step in this problem? Using a part-part-whole bar model and subtraction to find the remaining amount of dried peas. For the second part, we need to use division to find the answer.
Boy, this one can be tricky! We have our "whole" in this problem, and we know how much is in each "part", but we don't know how many "parts" there are. First we'll have to use division to find that out, and then subtraction to solve the second part.
In our final video, you will use multiplication to solve part A. After you know how much juice is in all the glasses, you can use subtraction to find the answer to part B!
