Addition is putting numbers together to find out how many in all. When we add, we combine two groups into one total.
Think of addition as "putting together." The answer is called the sum.
We can use objects, like counters, blocks, or drawings, to show how numbers are added together.
Use real items, like buttons or toys, to make addition hands-on and easier to see.
A number line helps us add by starting at one number and moving forward to add the other number.
Always move to the right when adding on a number line because the total gets bigger.
We can break apart numbers to make a sum of 10. This is a useful strategy for solving addition problems quickly.
Remember the pairs of numbers that make 10: 1+9, 2+8, 3+7, 4+6, 5+5.
We use addition every day when we count things, put groups together, or figure out totals.
Look around your home or classroom. Add groups of objects, like books, toys, or snacks, and find out how many there are in all.
