Answer 1

One way to represent 4⋅7 with a model is by using the repeated addition model, where you add 7 four times. This can be shown by drawing four groups of seven objects or by using a number line and counting by 7 four times. Another way to represent 4⋅7 is by using the multiplication model, where you multiply 7 by 4. This can be shown by drawing an array with 4 rows and 7 columns, or by drawing four groups of seven objects and counting the total. The end result of both representations is 28.
