There are so many toffees. Let's make a group of 10 and write 1 in tens place. Now, how many toffees are left? We write down 4 in the ones place. And what does this mean? It means that we have a total of 14 toffees!
On the other hand, when we say "less", we mean that there is a smaller amount of something. For example, if you have 10 pencils and your friend has 6 pencils, then your friend has less pencils than you.
Example: Count the number of balloons and tick the group with more objects.
The number of balloons in the first box is 16 and in the other box is 8. So the left group has more balloons.
Now, we can bundle the sticks into a group of 10. We take 6 sticks and add 4 more to make a bundle of 10. We write down the number 1 in the tens place (the column on the left) to show that we have one bundle of 10. Then, we write down the number of sticks we have left in ones place (the column on the right). In this case, we have 3 sticks left over.
