An “Addition and Subtraction to 20 Worksheet” is designed to help students practice the basic skills of addition and subtraction with numbers up to 20.
Addition:
- Direct Addition: This is simply adding the numbers together. For example, if the question is 8 + 7, you just add the two numbers together to get 15.
- Make 10 Strategy: This is a strategy often taught to help kids memorize addition facts. For example, if the question is 8 + 5, you would “make 10” by taking 2 from the 5 and adding it to the 8 to make 10, then add the remaining 3 to get 13.
Subtraction:
- Direct Subtraction: This is simply subtracting one number from another. For example, if the question is 16 – 7, you just subtract 7 from 16 to get 9.
- Counting Up: This is a strategy often taught to help kids memorize subtraction facts. For example, if the question is 15 – 8, you would start at 8 and count up to 15, which is 7, so the answer is 7.
- Make 10 Strategy: This strategy also can be used in subtraction. For example, if the question is 13 – 4, you would subtract 3 from both numbers to make it 10 – 1, which is easier to solve.
Remember to practice mental math to speed up your calculation time. Also, check your answers with a calculator or with a parent/teacher to ensure you are solving the equations correctly.
This worksheet is about practicing addition and subtraction with numbers up to 20, using the strategies you have learned. By solving these problems, you can become more fluent and confident in your basic arithmetic skills.
