Summarizing with Ormie!

0 Comments


In class this week, we are working on summarizing...


When writing a summary, focus on the most important details. Keep it short and use your own words to tell what happens. An easy way to stick with what's important is to use the SWBS Method.




For example, here is a SWBS Summary of Cinderella:



Now let's use our skillz to summarize "Ormie" by Arc Productions!






Now it's time to put SWBS to work with Pippi Longstocking!

 

Think about Chapter 7-8. 

Summarize one scene or event using SWBS.

We've Got the Power!

0 Comments


This week we're SUPER excited to learn about the SUPER Power of Ten! Using exponents is an efficient way to write numbers that have a few too many zeeeeeros.


Here are the vocabulary words for this lesson: 
powers of ten
base number 
exponent

The exponent (or power) tells us how many zeros are in the number when the base number is 10.



The image below has a place for everything with everything in its place. The base can be any whole number, but today we are only focusing on the POWERS of TEN!


The number above really means 10 x 10 x 10 = 1,000.
(exponent of 3 = 3 zeros)

Multiplying with powers of ten is SUPER fun! When multiplying a whole number by a power of ten, just count how many zeros you have and attached that to the whole number! If you use exponents, they'll tell you how many zeros you need. Just ask 'em.





Now for DIVISION...

The video below will explain how to use the power of ten to quickly divide numbers. The SUPER cool thing is that you can do all of this in your head. 



Dividing a number makes it smaller. When dealing with powers of ten, you just move the decimal to calculate your answer. In class today we remembered that a whole number has an invisible decimal on its right.

8.

As it says in your math book, when you multiply or divide by powers of 10, you just change the location of the decimal point. you can multiply by powers of 10 simply by moving the decimal point to the right the number of places shown by the exponent on the 10 (or the number of zeros in the power of 10, if written out). when dividing, move the decimal point to the left the number of places shown by the power of 10. remember that the decimal point is always located after the ones place, so in the whole number 23, the decimal point is located after the 3 ones.

Comparing (and Eating) Fractions

0 Comments

QUICK REVIEW! When dealing with fractions always remember that the numerator is the number on the top and the denominator is on "de-bottom."


Moving on...

This week, we learned how to compare fractions.  In math, we use universal symbols like 
<
>
=
to compare one number to another.

If you forget which way the symbol faces, just think of the ol' alligator.

He opens his mouth to the larger number. Why?


He LOVES big numbers. He DEVOURS them!

HE WANTS MORE!

Especially when you're talking about pizza, pie, or Hershey bars.


Who wouldn't want 8/8 of a pizza?

In the problem above, the denominators are the same. This makes comparing the two fractions easy. 

When comparing two fractions with like denominators, the larger fraction is the one with the greater numerator. Let's look at the example above. 8 is greater than 5, sooo...



Now, let's look at some more examples of comparing fractions with unlike denominators.


When you have fractions with unlike denominators like the two above, there are a few ways to figure out which is greater. One method is to find the Lowest Common Denominator (LCD).

First, write down all the multiples of each denominator...


Circle the lowest number that they have in common. This will become the new denominator for both fractions.

As we learned before, when making equivalent fractions you have to X or ÷ the denominator and numerator by the same number. 


Now that the denominators are the same, we can look at the numerator to see which fraction is larger. Which is greater 6 or 5? 6 is larger, soooo...



When I was in 4th grade, I learned another way to compare fractions. I've taught this technique to my students over the years because it's a little quicker than the LCD technique!




5 is less than 12, soooo...

This technique is also known as The Butterfly Method. Can you tell why?





This video will help explain a couple different ways of comparing fractions. Use the method that works for you!



When cross multiplying or finding the LCD, it may help to use a Multiplication Chart. Click the picture below for a cool chart to add to your math notebook!
