Math test on 12/9/2010

Dear Respected Parents:

On Thursday, December 9, we will be having a Math test on Chapter 3. Chapter 3 includes Two-Digit Subtraction, Estimating Differences, Subtracting money, Solving Story Problems, Subtracting Three-Digit Numbers, Subtracting Greater Numbers, Subtracting Across the Zeros, and Selecting Addition or Subtraction. All lessons are explained in detail in Chapter 3 of our textbook and there is also a practice test on pages 151-153. Students need to remember the following:

Vocabulary: Difference is the answer to a subtraction problem
Estimate is when you find an answer the is very close to the exact answer by rounding the numbers.
To regroup is to borrow ten from the next place value if the numbers in the ones place can't be subtracted.
You can check your answer to a subtraction problem by adding.
You can also subtract by drawing a picture using base-ten blocks.
When solving a story problem make sure you use the problem solving strategy we learned:

1. Understand what they are asking you to do. Look for word clues such as how many more, how many in all, how many are left over, how many more etc.
2. Plan: Draw a picture, draw base ten blocks, make a chart and do what ever works best for you to solve the problem.
3. Solve
4. Check: You can check a subtraction problem by adding and you can check an addition problem by subtracting.

If students are confused on any part of Chapter 3, they can make a note of what is confusing them and we can review it in class tomorrow inshallah. Jazakum Allah Khairan.

Respectfully,

Sister Maha
