Divison Decimals DLO

LI: Learning how to divide decimals.

Dividing Decimals , Dividing with decimals is easy once you get rid of the decimal point in the number you are dividing by.

  1. Fix the Outside Number. You want the number you are dividing by (the outside number) to be a whole number. To do this, hop the decimal point all the way to the right. 2. Match it on the Inside

Whatever you did to the outside number, you must do to the inside number. Move its decimal point the exact same number of hops to the right. Example: $12.6 div 0.3$. Change $0.3$ into a whole number by hopping the dot 1 time to the right. It becomes $3$. Do the same to $12.6$. Hop the dot 1 time to the right. It becomes $126$. Now your question is just $126 \div 3$, which equals $42$!

Multiplying Decimals DLO

LI: Learn how to multiply decimals.

Ignore the Dots and Multiply, Pretend the decimal points aren’t even there. Just write the numbers as normal, whole numbers and multiply them like you usually would.

Example: If the question is $3.2 \times 0.4$, pretend it is just $32 \times 4$.

$32 \times 4 = 128$.

  1. Count the “Decimal Places”

Go back to the original question. Count how many total numbers are sitting behind (to the right of) the decimal dots.

  • In $3.2$, there is one number behind the dot (the 2).
  • In $0.4$, there is one number behind the dot (the 4).
  • That makes two numbers behind the dots in total.
  1. Put the Dot Back In

Take your answer from Step 1 ($128$). Start from the very back of the number and hop the decimal point to the left. Use the total number of hops you counted in Step 2.

Since we counted two numbers, we make two hops from the back:

  • Start at the end of 128.
  • Hop once: 12.8
  • Hop twice: 1.28

So, $3.2 \times 0.4 = 1.28$!

 

 

Compound Shapes

LI: To calculate the area of a compound shape.

Compound shapes are really easy they have 2 different type of widths if you add them together you end up with an answer. To find the area of an compound shape you break it down into shapes you know. Then add each of them add both of them together then you find the missing side and use the measurements you already have to check and missing side length needed to find the area

Then you sum up each of the areas to find the answer.  

Classifying 2D And 3D Shapes

Classifying 2D Shapes

Classifying just means sorting shapes.

For 2D (flat) shapes, we look at their sides and angles:

Triangles (3 sides) Equilateral: All 3 sides are the same length. Isosceles: Only 2 sides are the same length (like a pair of pants). Scalene: All 3 sides are different lengths. Right-angled: Has one perfect 90degrees  square corner.

Quadrilaterals (4 sides)Square: 4 equal sides and four $90 circe corners.Rectangle: Opposite sides are equal lengths, with four $90 circe corners. Parallelogram: Like a leaning rectangle. Opposite sides are parallel (they run side-by-side like train tracks and never cross).

Classifying 3D Shapes.3D shapes are fat, solid shapes you can hold. We classify them by counting three things: Faces: The flat surfaces you can press your hand against. Edges: The straight lines where two faces meet. Vertices: The sharp corners (points) where edges meet.

 

Volume DLO

LI: To explore what volume is.

Today in LS2 we are learning what volume is, volume is something like the inside or the amount of velocity inside an object or shape. We can also call volume the measurement between three or two dimensional shapes.

There are different formulas on weather we can do it. For example the volume for a cubed shape is _ x _ x _ x which equals to your answer just like the example on the top. 

Triangle


LI: How to identify different types of triangles.

Today we have been identifying and learning about types of triangles and what they are used for, they’re are two categories, the two categories are called on based on and there names are the triangles of angles and triangles of sides. We can use triangles to determine what and how the length of something is. For example, Pizza what type of triangle is that your friend asks, now you have to answer that question, later on you say equilateral triangle because it’s sometimes looks basically the same but the only difference between the two objects that we are comparing together.

After this activity we had a lot of knowledge about these types of triangles while helping each other.

 

Converting Measurements DLO

LI: To convert between metric units of lengths wight and volume. 

Converting is really easy all it takes it to multiply it by itself all you need it a formula. Just get your type of measurement in this case i’m using 100 centimeters to do this then you times it by 10 to make 1 meter because 10×100=1000 which is 100cm x 10 that becomes one meter its that easy!

Subtracting Decimals DLO

LI: How To Subtract Decimals Using Algorithms.

Today in LS2 for maths we are learning how to subtract with decimals, but to subtract decimals we can use the regular way on how we subtract. For example first we a line all the correct numbers, then we can now start to do the subtract process just like the image above.

After subtracting the numbers we now have to perfectly a line the decimal points because it helps us get the total correctly especially when starting to process everything. But we always have to remember to put in the correct numbers along with there decimals because it is very important to get the right answers, and one more thing is that we should always remember the different formula’s

Adding Decimals

Today In LS2 in our Group we learned about how to add up decimals using algorithms, after learning and exploring what the square roots we’re everyone in the group looked forward to looking for our new topic, this new topic was called decimals but for the meantime we are still on the adding up part.

While doing decimals, we should always put to mind to put the decimal points and numbers all a linded. During this lesson me and my group mates knew how to add them up because it’s just like regular adding of numbers, but the only new thing we had to remember was that there was a decimal every after a number. Though this lesson was very fun we also had a very great understanding on how we can do it now, we also helped each other on how we can get the correct answers.

 

Tech

Today was our second week in our new tech class. When we arrived, my tech group walked together to our classroom and greeted our teacher, Miss Royh. She started by taking attendance, and then we dove into our first lesson.

Our first task was to explore different designs to get some inspiration for our cushion projects. Once we finished choosing our favorite ideas, we created a Google Doc to showcase them. After that, we moved on to the sewing machines. We watched a short video that showed us how to thread the machine, and then Miss Royh gathered us into groups to demonstrate it in person. Because I listened carefully, I easily got the hang of it and completed the task.

I raised my hand to let Miss Royh know I was done, so she came over and placed a bobbin into the machine. I started the machine up and began practicing on a piece of fabric. Before I knew it, we ran out of time and had to pack up and clean the classroom.
