How to write repeated addition & multiplication expression for for equal groups
For the topic Repeated addition quiz and multiplication for equal groups we are going futher in multiplication explanation with some tests on writing repeated addition & multiplication expression for for equal groups. Let’s use the following equal groups and describe how to process.
When showing repeated addition it’s important to follow some steps. Don’t forget that the good way to explain it to children is to drive their attention the way they must understand it as __ groups of __. Here are 6 groups of 4 peaches.
Therefore, the repeated addition equation should first take the number of objects in each group and add it repeatedly to match the number of groups. As you can see with our example, we can read
4 + 4 + 4 + 4 + 4 + 4 = 24.
It’s true that the commutative property allows for either, but don’t forget that we are teaching kids and the good strategy while explaining this example is to make them understand the difference between 6×4 and 4×6. For multiplication expression, 6×4 represents 6 groups of 4 and 4×6 represents 4 groups of 6.
Please take note of that! This distinction is really important when solving multiplication word problems. That’s why if you write the answer the wrong way (using commutative property) while solving out tests, the answer will be supposed to be the wrong one and the game will display “false”.
For the current example, the multiplication expression is suppose to be 6 x 4 = 24 & repeated addition is 4 + 4 + 4 + 4 + 4 + 4 = 24
