Counting 10 more 

Lulu the chicken has laid 7 eggs. If she lays 10 more, she will have 7 + 10 eggs. That’s 17 eggs!

This is how to do the sum:

    7
+10
____
  17

7 plus 0 is 7

1 plus nothing is 1.

If Lulu lays 17 eggs and then lays another 10 eggs, we will have 27 eggs:

   17
+10
____
  27

7 plus 0 is 7

1 plus 1 is 2.

The trick is to add 1 to the number before the last number!

 

Now let's start the activities.
