Math
Several students had difficulty with subtraction on measurement test last week. For two weeks we are going to leave multiplication and division and review addition and subtraction including addition and subtraction with decimals. Subtraction across zeros seems to pose the greatest challenge.

These are three strategies we talked about today.

When we are using a number line, we are adding up to find the difference between two numbers. What do we have to add to 2142 to get 8000?
We add up in "chunks".
Add to the nearest ten, then nearest 100, then nearest 1000 and finally to the end number.
Add all the "chunks".

When we make an easier question, we are shifting the numbers, but the difference remains the same. Using a simple subtraction sentence:9 - 2 = 7
If we take one away from the each of the numbers on the left of the equal sign, we will still get the same difference. We are just shifting the difference. 8 - 1 = 7. You could also add the same number to each and get the same difference. We subtracted 1 from 8000 because our new subtraction question has no regrouping and that's easy!

The last way we practiced today was regrouping. If we look at 8000 as 800 tens and take one group of ten away we are left with 799 tens. We take that one ten and regroup it was 10 ones. Then we subtract from right to left.

If you did not complete the two question in class ALL THREE WAYS, please finish for homework.
1. 8000 - 2142
2. 4000 - 1083

Complete the homework questions below in your yellow math notebook:

Using a number line:

3. 9000 - 6295
4. 7000 - 5329
5. 4000 - 1837

Making an easier question:

7. 3000 - 1249
8. 5002 - 2263
9. 9001 - 5718

Standard Algorithm (regrouping)

10. 5001 - 3029
11. 2000 - 728
12. 7003 - 4816

Literacy
For the next few weeks we will be reading several pieces of HISTORICAL FICTION. Historical fiction has the same characteristics of a regular fictional story (narrative), with a few added characteristics.

The read aloud today,  "Naomi's Road", was about two children that we sent to Japanese internment camp in Canada during the World War II. Chat with a parent about the reason why the Canadian government decided to take this extreme measure. Do you think it was fair? What we read today was just an excerpt from a book. Unfortunately, they do not have the book at the London Public Library. It was also made into an opera!

The reading strategy that we practiced was making inferences. When we make an inference, we draw a conclusion based on what we have read and our own knowledge or schema. When we infer while reading, we are thinking about not only decoding the words, but the meaning behind the author's words.

Religion
If you did not finish your chart on the different examples of actions that turns us toward God and actions that turn us away from God, please complete it on Wednesday.

Writing
We continued practicing writing dialogue using quotation marks. Here are the next two picture prompts for Wednesday. Remember dialogue....

• Conversation between characters
• Reveals the personalities of characters
• Keeps the story moving along (need detail to accomplish that)

Our practice is only one character so far, which isn't technically dialogue. Most students are learning the rules of using QUOTATION MARKS.

Reminders:

• No school tomorrow (Tuesday, February 4th)
• Permission form for tubing
• Professor Jamz pledge sheet
• Mathletics assignments
