You get to decide which apps to lock behind learning using 1Question.
Learning time
Kids learn by watching short, engaging video lessons.
An array is a type of picture that we use to help us visualize and solve multiplication equations. In this type of picture, you will have items that are in rows and columns. So, they will go up and across kind of like in a rectangle. To help us see how this works, we're going to look at the equation 3 x 5. In this equation 3 is the first number. So, this means there's going to be 3 rows so you're going to have 3 items going up. The second number in this equation is 5. This means there's going to be 5 items in each row. So, you're going to have 1, 2, 3, 4, 5 going across in each row. If you count all of these items altogether in the whole array, there's 15. That means that the answer to 3 x 5 is 15.
