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.
