In fourth grade, you'll learn lots of different ways to multiply numbers. Sometimes you can use repeated addition, other times drawing an array helps, and sometimes breaking apart numbers into smaller parts makes it easier! This quiz helps you practice choosing the best strategy for each problem. Think of it like having a toolbox full of multiplication tricks – you pick the right one for the job!
Think about what works best: Is the problem about adding the same number over and over? Maybe repeated addition is the way to go! Are you trying to visualize the problem? An array could be perfect! The more you practice, the faster you'll become at choosing the best strategy!
Match the term with the correct definition:
| Term | Definition |
|---|---|
| 1. Array | A. Breaking a number into smaller parts to make multiplying easier. |
| 2. Repeated Addition | B. A rectangular arrangement of objects in rows and columns. |
| 3. Distributive Property | C. Adding the same number to itself multiple times. |
Write the correct letter (A, B, or C) next to each number.
Complete the paragraph with the missing words:
The _________ property helps us break down multiplication problems. For example, to solve $6 \times 7$, we can think of it as $(6 \times 5) + (6 \times ____)$. Repeated _________ is helpful when we're adding the same number multiple times. An _________ uses rows and columns to visualize multiplication.
Explain, in your own words, when it might be better to use an array model for multiplication versus repeated addition.
