1. Build a Factor Tree.   Break your big number down into smaller building blocks called  
2. prime numbers (numbers that can’t be split up any further, like 2, 3, 5, or 7). Keep splitting the numbers until you reach the bottom of the tree.
3. Make Groups of Three.  Cube roots are all about sets of three. Look at the numbers at the bottom of your tree and group them into matching trios (three of the exact same number).
4. Pick One from Each Group. For every threes  you made, just take one number out. 

Multiply Them Together. Multiply those chosen numbers together, and boom—you have your final cube root answer!

LI: How to identify multiples of numbers and find the lowest common multiple of two numbers.

In LS2 maths group 4B are learning on how to identify multiples and find there lowest two common multiples of two numbers, when trying to find the LCM we have to list they’re different multiples in order to get there lowest common multiple. The lowest common multiple is the smallest multiple of any numbers for example to find the LCM of 4 and 6 we need to list there multiples, 4, 8, 12, 16, 20, 24 and so on but for 6 is 6, 12, 18, 24 and so on, then when you’re done listing we can now find the LCM which is 24 because 6 and 4 both share the same number. When we did this topic we had some difficulties but in the end we all still copped with eachother and understanded.

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.

LI: How to know different angles and positions.

Greeting evrybody today I will show you what angles are and identify them. first of all you get a protractor which is like an angle tool. after you put the protactor on the angle if its pointing at 90 degrees that means the angle of the line is 90 degress it’s that easy! made By group 4B.

There are different angles, they all come in different shapes and positions.  For example the right angle goes about 90 degress, we use angles for finding the measurement or length of something just like when we use a protractor. Anyways this lesson was very fun because we all helped each other and we also had lots of knowledge about this lesson now.

LI: To calculate the perimeter of a compound shape.

Perimeter something very interesting What Is a perimeter? A perimeter is a really wide length of something, to find a perimeter you need to add up all the lengths and faces of the shapes there a lot of ways to get the perimeter. An example is there is a square the formula is per-4x you times it by 4x then you get the answer or a rectangle its length x width.

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 $90^\circ$ 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.

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.

As for this lesson it was very fun and very cheerful, after the lesson of converting measurements we all in the group can now endure and get the following up lessons precisley. It was also very exciting for us because we we’re going to learn about something new.

LI: To calculate the area of a parallelogram.

For today’s stand activity we have been focusing on Parallelograms . A parallelogram is a 2D flat shape which is called ‘ quadrilateral that have four straight .But really a Parallelogram is a two-dimensional geometrical shape whose sides are parallel to each other . We have been solving the Area = Base X Height . For example Base (b): The length of the bottom side of the shape.

Height (h): The vertical distance (measured at a perfect 90 degrees right angle) from the base to the highest point of the shape.

Today in LS2 we are learning how to read scales, reading scales can be very easy and and both hard to . For example we use scales when we have to weigh or get the exact weight or exact measure of what we are weighing.

After learning this lesson the group understanded neatly and it was quite very fun because everyone cooperated and worked together.

But while we we’re working together we had some worries because some of us got the right answer while the others still didn’t get it, and that’s why later on the people who got it they all helped each other to get the correct answers this time.

This lesson was very fun especially when everyone got together and heaps of fun.

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.
