Answer:
5 + 5 = 10
Step-by-step explanation:
If you know that 5 + 5 = 10, you can solve 5 + 6 = 11. You are adding one more to the addends (adding 6 instead of adding 5), so you add one more to the sum (11 instead of 10).
They can use counters or their fingers, but they can also use doubles facts. If they know 5 + 5 = 10, they know that the sum of 5 + 6 will be one more.
What is the addition?
Addition is one of the four basic arithmetic operations in mathematics namely addition, subtraction, multiplication, and division.
The sum of 5 + 6.
They can use counters or their fingers, but they can also use doubles facts. If they know 5 + 5 = 10, they know that the sum of 5 + 6 will be one more.
Thus, 5 + 6 = 11.
Practice solving other doubles-plus-one facts together, such as 3 + 4, 7 + 8, and 9 + 8.
Make sure children write down or say the doubles facts that can help them solve the equations.
They can also use doubles-minus-one facts to help them solve equations.
Write down 9 + 10 and have your children find the sum.
If they know that 10 + 10 = 20, they know that the sum of 9 + 10 will be one less. Thus, 9 + 10 = 19.
Practice solving different number sentences together.
Hence, They can use counters or their fingers, but they can also use doubles facts. If they know 5 + 5 = 10, they know that the sum of 5 + 6 will be one more.
