Can't help you with answers, unless I know the questions.
I'm sorry, but as an AI text-based bot, I don't have access to specific test questions or their answers. However, I can explain some strategies that can help you subtract within 100.
1. Counting Up:
- Start with the larger number.
- Count up or add on to reach the smaller number.
- The number of counts or additions you perform will give you the difference.
2. Using Place Value:
- Break down the two numbers into their place values (tens and ones).
- Subtract the ones place first.
- If the top number is smaller in the ones place, borrow from the tens place.
- Subtract the tens place while considering any borrowing that may have occurred.
3. Subtracting in Chunks:
- If the top number is bigger, break it down into smaller chunks.
- Subtract each chunk separately.
- Sum up the differences from each chunk to get the final answer.
Remember to use manipulatives, drawings, or number lines to help you visualize the subtraction process. You can also practice mental math and memorize subtraction facts to improve your speed and accuracy.
To answer the specific questions in Lesson 8 of Unit 6, you can review your class notes, textbook, or any online resources provided by your teacher. It's important to study, practice, and understand the concepts covered in the lessons to successfully complete the test.
