Before we start with multiplication, let’s look at lots. When we say lots, we are talking about groups e.g. If we say 2 lots of 2, it means that there are 2 groups of two.
From the example above, we can see that there are 2 boxes and each box contains 2 items. Therefore when we put these items together in one box, we have 4. We can then conclude that 2 lots of 2 is 4.
