Count a Group and Add One
Count each object once and find how many there are after adding one.
Supplied materials
- Paper and a pencil, or say your answers aloud.
Learn the idea
When you count, give each object one number: one, two, three. The last number tells how many objects are in the group. Touch or point to a drawing as you count so you do not count it twice.
One more means adding just one object. If a group has four objects, the next counting number, five, tells how many it has after one more arrives. Moving the drawings around does not change how many there are.
- Draw four circles. Point to each circle and say one, two, three, four.
- Draw one more circle and count the whole group again.
- Draw a new group of six circles, add one circle, and find the new total.

Four drawn apples and one more apple make five apples: 4 + 1 = 5. Counting all five drawings checks the answer.

7 stars
The six stars stay, and one new star joins them. Counting one number after six gives seven: 6 + 1 = 7.
Take it further
Start with three circles instead. Add one and count four. Ask an adult to move the four drawings into two rows; count again to check that there are still four.
