Comparing Numbers for Kindergarten
Comparing means looking at two groups or two numbers to decide which has more, which has less, or whether they are the same. Counting carefully helps us compare with confidence.
What Does Compare Mean?
When we compare, we look at two things to see how they are alike or different. In math, we often compare groups of objects. We ask questions like: Which group has more? Which group has less? Are they equal?
If one plate has 4 crackers and another plate has 6 crackers, the plate with 6 crackers has more. The plate with 4 crackers has less.
Match Objects One by One
A great way to compare is to line objects up and match them one by one. If every object gets a partner, the groups are the same. If one group has extras left over, that group has more.
This strategy works even before children feel ready to compare written numbers.
Use the Words More, Less, and Equal
More means a bigger amount. Less means a smaller amount. Equal means the same amount.
Try saying full math sentences: "Seven is more than five." "Three is less than eight." "Four and four are equal." Using the words out loud helps children build strong number language.
Compare Written Numbers
After counting objects, we can compare written numbers too. If you know the counting order, you already know a lot. Numbers that come later when counting are greater. Numbers that come earlier are smaller.
For example, 9 is more than 7 because when we count, 7 comes first and 9 comes later.
