Ages 2–3
Add One Apple
Count the apples you see, then press the button to add one more and count again.
About this activity
Add One Apple is a first introduction to addition for toddlers ages 2–3. Children count a group of apples, tap a button to add one more, and count again — discovering, through play, that adding one always makes the group bigger by exactly one.
Skills practiced
Early addition, Counting, Number sense, Cause and effect
Tips For Parents
Ask ‘how many now?’ before your child counts again, to build the idea that adding one changes the total.
