February Eureka Apprentice

February Eureka Apprentice

Study/Learn

Welcome to Eureka!  Are you ready for some amazing discoveries, engaging conversation, and fascinating inventions (YOUR inventions)?

1. Pull out the ancient calculating device.  We will not be working on the abacus in class, so you don't need to bring it unless you want me to help you figure it out and catch up.  Keep practicing, though!

Beginner Abacus Students: 


Continue practicing by filling out out worksheet #4 from this PDF File.   Fill our 10 problems from each row...that way you only do 1/2 the worksheet, but get some harder problems to work on from the bottom of the page. 

If you have any questions on the problems, please call me! 719-494-7522.   Remember, this will get really useful with bigger numbers!

Here is the addition video, watch this video with your abacus in hand, and work the problems with her.

Intermediate Abacus Students: Here is a link to 2nd level abacus worksheets.  Print and complete at least 1/2 of worksheet #4. Work on 10 problems from each row.

To continue our multiplying, solve each of these problems.  Let's just focus on a large number multiplied by a 1 digit number, so we can master that skill.  Write the answers you got on your abacus in your commonplace book.

5437 X 5
2398 X 9
8245 X 3

These videos may be helpful as you remember how to do this.  Mostly the 2nd one:

VIDEO 1 is HERE!

VIDEO 2 is HERE!

2. N2K...If you need to remember the game, rewatch National Number Knockout. Watch the Rules Here.  Play this game for at least 10 minutes with a parent or sibling.  Play to get a base score, then play again to beat that score by 20.

We will be playing in class!

What can you do to to increase your score?  
What's a good strategy?  
Remember, if you understand how to use your 1 free exponent, use it!  If that seems overwhelming, don't use it, just multiply. 
This game is awesome to help you get your facts down, or get faster at them!

4. BIG Reports -- Reports that last about 5 minutes, with fun, engaging information, examples, content, and visual aids.

Everyone (except the report givers, Chris, Jaykob, and Kylee), bring 1 interesting fact about Anders Celsius.  Seriously interesting.  We don't care where and when he was born or died, etc.  Make it pertinent to his life in science, and .....interesting!!!

February	Anders Celsius (1701-1744)
	Benjamin Franklin (January 17, 1706-April 17, 1790	Chris Eagar
	Leonhard Euler (1707–1783)	Jaykob Fontano
	Maria Agnesi 1718-1799	Kylee Martin

5. Make these note cards from the Dictionary of Cultural Literacy:

Crystal

Decimals

Electron microscope

Flat universe
hypothesis

Mean

Median

Mode

6. Create another invention, like we talked about in class.  I love to see all your ideas! If you'd like to make some type of sun oven or rocket stove, there are lots of ideas online.  You can even copy mine...I got the idea online.  It can be original, that's even better.  Most of all, make sure it's useful!

If you've already started on an invention, work on it, or do something to improve it or make it better.

Do not bring it to THIS Eureka.  We will be showing them in March.  You have time.  Don't procrastinate.......:)

7.  Watch this video on Math and Music Because Music will be a part of our day!

Know/Understand

8. Do 1 of the following:

Math is sooooo Coooool!  Like, totally so cool. Because it's all about patterns.  Choose one of these patterns.  But be careful, because it's addicting, and you might just try all 3. Free time fun! 

Solve this Krypto:  Here are 6 numbers:

2, 4, 6, 7, 9, 12

Your Target number is....157

Bring in your answer in correct mathematic equation form.

Rules: Using each of the 5 numbers ONLY ONCE, you may use any combination of addition, subtraction, multiplication or division to manipulate the 5 numbers in any order to reach the target number.

Example: if you had the 5 numbers: "8,4,1,6,3", you could reach the target number of 11 by doing: 3 x 4 + 1 - (8 - 6) 

There is always a way, usually more than 1, to reach the target number.

Use your commonplace book to record your trial and error. Record your equation and bring it to class!

OR

Solve some multiplication problems Japanese style.  Watch this video.  

Then solve THIS problem in your Common  Place book: 

35 X 21

OR

Try this logic page.  You'll need to print it out. 

This is NO Number Logic.  Try it!  And Bring 

it to class!
