Grade 10

Math 10 Week 3

keishan2015

This week in math 10 we learned all about exponents. Although the beginning of this unit was review I learned quite a bit about solving equations involving exponents. This week one of the things that I learned was how to solve fraction exponents. I also learned a phrase to remember when solving these types of equations, “flower to the power, root to the root”.

Example:

How to solve the problem:

  • You look at the fraction exponent and determine which number is the flower and which number is the root of the flower, the numerator will always be the flower and the denominator will always be the root. the flower will act as the power of the radicand and the root will go in front of the root sign acting as the index.
  • Next, you find the root of the radicand, after finding the root you should be left with the root of the radicand and an exponent. You then multiply the number by itself as many times as the exponent calls for. what you should be left with is the answer to your equation.

 

Math 10 week 2

This week in math 10 we learned about mixed radicals and entire radicals. Something that I learned how to do was how to covert mixed radicals into entire radicals.

  1. To turn a mixed radical into an entire radical you need to covert the coefficient into a square root. to do this you must square the coefficient.
  2. Next, you multiply the two square roots by one another to get the entire radical

Example:

Float Your Boat

1.Problem

We had a lack of knowledge, time, and materials when creating our boat. If we had known more about the structure and how the weight of the pennies would effect the boat then our result would have been different.

2. Hypothesis

If we place the straws on the bottom of the boat then it will help support the weight of the pennies because due to the structure of the straw it will help act as a floating device.

3. How Many Pennies?

Our boat was only able to hold 20 pennies before it sunk.

4. What Was Your Thinking/Reasoning Behind the Design of Your Boat?

When we were creating the boat what we had thought initially was that the sticks would help support the weight of the pennies, the straws would be used as a floating device, and the tin foil would help protect the straws/sticks.

5. What Would You Change or Keep About Your Design?

If I were to make the boat again I would have still kept the tinfoil folded over to protect the sticks but I would have placed the straws on the outside of the foil still using it as a floating device. I also wouldn’t fold the foil in half because that is how the water had gotten into our boat, helping it sink.

Math 10 Week 1

This week in math 10 we learned about numbers. Though it was mostly a review of things that I’ve done in my previous years of math one thing I learned is that if you are only given the prime factors of a number it can tell you quite a bit about that number. With only its prime numbers you can find both your mystery number and ALL of its factors.

  1. You start by writing down the prime factors that are already given
  2. Then, you would cover one of the prime numbers and multiply the other prime numbers together to find what the covered numbers pair (the number that you would multiply the covered number by to equal the mystery number) is. Repeat for the other prime numbers.
  3. Next, you multiply the prime numbers in pairs, making sure that you multiply each number by all the other prime numbers given.
  4. Make sure you don’t forget to add 1 and the original number (multiply all the prime numbers together) on the list of factors

Immigration Journal Reflection

My journal entries:

immigration-journal-edited

 

Reflection:

Personally what I thought was most successful in my project was the story line of my character and the feelings that I portrayed throughout the story. I also felt that as a whole everyone was successful when they tried making their journals look as old as possible. What I would have liked is if we could have had more say in the criteria of the immigration  journal, other than that I wouldn’t have changed anything. While doing this assignment I learned more about black slavery and how it effected those who lived through it, I also learned how to tea stain. I thought that the project was a fun and creative way to further understand slavery and the immigration to Canada.
