Literacy
New words were given out this week. We have words with a double o that have two different sounds. One sound is like the word soon (the eerie sound) and the other is a short sound like the word good.
I think everyone completed the word sorts in your blue notebook. Please practice sorting your words every night. Your test will be next Monday instead of Friday.

Keep working on writing dialogue correctly. Most students are starting to applying rules correctly. Bravo! Here's the funny picture for tomorrow:

Math

Today grade fours worked with some magic red and magic blue potion..... The red potion made a number 10 times as small while the blue potion made a number 100 times as small. I think everyone understood that when you divide a multiple of ten  by 10, one zero "disappears" and when you divide a multiple of ten by 100, two zeros "disappear". But why? Let's look at an example.

450 ÷ 10 = ?

If you divide 450 into groups of ten you would have 45 tens so the answer is 45. The numbers shift one to the right on the place value chart.

6700 ÷ 10 = ?

If you divide 6700 into groups of ten you would have 670 tens so the answer is 670. The number again shirts one to the right on the place value chart.

4500 ÷ 100 = ?

If you divide 4500 into groups of hundreds, you would have 45 hundreds so the answer is 45. The number shifts two the the right on the place value chart.

In grade 5 we began talking about a strategy to multiply 2-digit by 2-digit numbers. The first strategy used an area model. Let's look at an example.

47 x 32 = ?

We can construct divide a 47 x 32 rectangle into 4 rectangles, find the area of each, then add all the products.

Rectangle #1    40 x 30 = 1200

Rectangle # 2    30 x 7 = 210

Rectangle #3    40 x 2 = 80

Rectangle # 4   7 x 2 = 14

If we add all the areas we get a product of 1504

Try this product using a rectangle model:

28 x 55

Science

Tomorrow we will continue talking about the arrangement of particles in solids, liquids and gases. Next up is CHANGES OF STATE.

Reminders:

• Trip to see "Anne of Green Gables" tomorrow. Bring extra snacks because we will get back to the school at around 1:00 pm. Your hot lunch will be waiting at school if you ordered, but lunch will be a little later.
