An early understanding of addition and subtraction can be seen when children experiment with:
Counting the number of items in a group of objects.
Adding objects to a group.
Removing objects from a group.
Comparing groups of objects—to figure out which has more or if they have the same amount.
Many simple number problems come up during your child’s day.Turn these moments into opportunities to build her growing addition and subtraction skills. As you sort and fold laundry, count with your preschooler to discover how many socks and how many pairs. Ask your preschooler to help you set the table: “Aunt Rini is coming to dinner. We will need one chair. There are 3 people in our family and Aunt Rini makes one more. How many chairs do we need altogether?”Play simple board games (or make up your own). Counting the dots on dice to find out “how many altogether” is great practice in counting and adding for preschoolers.
