“Altogether” means adding the pencils both children have. Add the second child’s number of pencils to the first child’s number.
Use the numbers in the text, rather than counting the pencils in the illustration.
Adding means putting two amounts together. Start with the first number and count forwards as many steps as the second number tells you.
For example, for 3 + 2, count 4, 5 after 3. Adding 0 leaves the number unchanged.
Adding 2 means adding 1 twice. Take two steps forwards from the given number.
For example, to add 2 to 4, count 5, 6.
Find how much more to add to reach the number after the equals sign.
You can also subtract the known number from the total. Check by adding.
First add the two numbers in the question. Then look at the equations in the answers.
In the correct equation, the number after = is the sum you found. Both sides of an equation must show the same amount.
More apples were added, so add the two numbers. Add the number of new apples to the number there were at the start.
Use the numbers in the question. The picture is only an illustration and does not show the amount to count.

Addition tells how many objects there are after joining two groups or adding new objects. The + symbol means “add”, and = introduces the result, called the sum.
Start at the first addend and count forward as many steps as the second addend shows. Addends may change places without changing the sum. In a word problem, phrases such as “more”, “altogether” and “in total” often indicate addition. Check that the result is no greater than 10.
Read pictograms, compare their rows, and find how many objects a key symbol represents.
