In this topic you need to know the values for the customary units like if you want to know how many cups are in four gallons you need to know the other units like 1 gallon equal 4 quarters 1 quarter equals 2 pints and 1 pint equal 2 cups and then do the process first you multiply 4 times 4 because there are 4 gallons and each gallon equals 4 quarts so there are 16 quarts then multiply 16 times 2 because 1 quart equal 2 pints and that is 32 and finally you multiply 32 times 2 because 1 pint equals 2 cups and the answer is 64 so 4 gallons are equal to 64 cups.

In this topic you need to know the two ways to recognize the temperature. Degrees Fahrenheit and degrees Celsius (F and C). If you want to know what temperature are in each type you need a thermometer. that helps you to see the temperature and if you want to find the temperature change there are 2 different types of change. The one that decreases and the one that increases. To know if it increases you need to know the 2 temperatures like 34 degrees Fahrenheit to 67 degrees Fahrenheit you need to subtract 67-34=33 so the temperature change was of 33 degrees Fahrenheit.

In this topic you need to understand that making a table makes the work easier and an example is this: You can type 72 word per minute.you need to type a paper with 432. How many minutes it will take you? To do this you need to do a table. Like to spaces the one of the top is for the words you type per minute and the one of the bottom is for the minutes you take so if we know that you take 1 minute to write 72 words, you need to add 72+72= 144 then 144+72=216 and it pass 3 minutes so then you add 216+72=288 then 288+72=360 and finally you add 360+72= 432 words and you take 6 minutes.

The topic 14-5 is the same as 14-4 but in this topic you compare too. to convert metric units it’s almost the same as 14-4. First you need to know the measurements you want to convert then if if you want to convert like kg to g you need to move the decimal point that is behind the 8 of 9.8 and then you move it 3 spaces to the right and you have 9800g. And to compare is the same first you need to know what measurements you want to compare.then you need to make the unit the same of the other unit like 10kg to grams that is 10000g and you want to compare 10kg and 9600g so 10kg is greater than 9600g.

Topic 10 -3 Adding fractions with unlike denominators

When we are adding fraction with unlike denominators we need first of all we need to get the LCM of both denominator and when we get it we need to see which number we multiplied to get the LCM as the denominator so we miultiply like we needed 2 to become 4 so we multiplied by 2 the denominator so the numerator will be multiplied by 2 and then with that we just normally add the fraction like with a like denominator.

-A prism is a polyhedron with two congruent,&nbsp; parallel, polygon-shaped bases.

-A prism is named by the shape of its bases.&nbsp; -The other faces are parallelograms.

Volume is the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.

This topic is the same as 14-6 but is from am to pm or pm to am like if you want to find the elapsed time between 9:50 pm to 4:00 am you first need to add 12 hours to 4 because pm and am both lasts 12 hours each so now is 16:00 - 9:50. First you add 60 minutes to the two zeros in 16:00 and now it is 15:60 - 9:50 60-50=10 and 15-9=6 so the elapsed time from 9:50pm to 4:00am is 6h and 10 minutes.

-A pyramid is a polyhedron that has one base.

-A pyramid is named by the shape of its base.&nbsp; -Triangular faces join the edges of the base to a&nbsp; point outside the base, which is called a vertex.

The types of quadrilaterals can be classified by relationships of their sides and angles

Subtracting mixed numbers its the same as adding but we subtract so first we get the LCM of the fraction as denominator and we continue with the procces and here instead of adding we will subtract and subtracting the whole by the whole.

Topic 10 - 2 Common multiples and least common multiple

The least common multiple its the least factor both numbers have in common like 5 and 20 their LCM ( least common multiple ) its 20 because the first number they have in common on their time table its 20 but like with 6 and 7 their least common multiple its 42 because its the first number they have in common on their time tables.

-A net is a plane figure pattern which, when&nbsp; folded, makes a solid.

When we add mixed numbers we need first to add the decimals as we should already know but then we will add the whole number because this is a mixed number so we add them and get like whatever number but if our numerator gets bigger than the denominator we will add as many wholes as we can.

In topic 14-6 it is about elapsed time. That means the time that has pass from a certain hour to certain hour. Like if you want to know the elapsed time that has pass from 9:59 PM to 10:45 PM. First you need to subtract 10:45 - 9:59. To do this process first you need to see if 59 can be subtracted by 45. If not you need to grab an hour from 10 and it converts to 9:45 and then you add 45+60 because 1h=60 minutes and that is 105 so now it is 105-59=46min and 9-9=0h so the elapsed time from 9:59 pm to 10:45 pm is 46min.

Triangles can be classified by various properties relating to their angles and sides

View of Solids are the part from your view your seeing the figure.

The three sides of view are: top view, front view and side view

-A polyhedron is a three-dimensional figure made of&nbsp; flat polygon-shaped surfaces called faces.

-The line segment where two faces intersect is&nbsp; called an edge.

-The point where several edges meet is called a&nbsp; vertex.

Green geometrical pattern

The distance around a polygon is called the perimeter of the polygon. The perimeter of a polygon is the sum of the lengths of its sides. 

The formula for the perimeter of a square ( which has all of its sides the same length) is :

The area of a figure is the amount of surface it covers. The area is measured in square units.

Example: a rectangle has a length of 4 units and a height of 3 units. Its total area is 12 square units.

Blue geometrical pattern

One customary unit of length is the inch. On most rulers it is divided into fractions to help you mesure more precisely.

The easiest way to measure centimeters and inches is to use a ruler. A ruler have 30 centimeters and 12 inches, and 30 centimeters is equivalent to 1 foot.

Example: we are mesure the nail so when we check we need to put the nail on the centimeter side, so then we mesure. It is near to 7 si the nail is 7 centimeters long.

This topic is almost the same as 14-2 and 14-1 but is Units of weight and Mass like the weight of a truck first you need to know what are the Units of weight and mass like Tons, kilograms,pounds, and also ounces then you need to think about a truck because a truck is very heavy so you need to think what unit of weight it can be Tons or kilograms. There is more sense to be tons because trucks are very heavy.

An irregular shape doesn't have equal&nbsp;sides&nbsp;or equal&nbsp;angles . For example, an&nbsp;equilateral triangle &nbsp;is a regular shape because all the sides are equal and all the&nbsp;angles&nbsp;are equal.

Red geometrical pattern

A circle is a closed plane figure made up of all points the same distance from a point called the center. A diameter a any line segment through the center that connects two points in a circle. A radius ( plural,radii) is any line segment that connects the center to a point on the circle. A chord is any line segment that connects two points in a circle. A central angle whose vertex is the center of the angle. An arc is part of a circle connecting two points of the circle. An arc that connects the endpoint if a diameter is a semicircle. A sector is a region bounded by two radii and and arc.

Making a generalization is telling that everything or everyone does something or has something

Example of a generalization: All triangles have right angles. that is false because obtuse triangles and acute triangles don’t have right angles.

Topic 10 - 1 Adding and Subtracting with like denominators

When adding and subtracting fraction with like denominators the denominator will never change so we will just add the numerator when we have the special case that the sum of the numerators is more than the denominator we will add one whole and the fraction but we need to check that our answer can't be simplified because if we can still divide it we need to get it to simplest form we will know that its in simplest form when we can't divide the numbers by the same number like our fraction its 2/4 we can divide both by 2 so we will get 1/2 and thats in simplest form.

Which tiles can be used to&nbsp; cover a 9x9 ft floor?&nbsp;

When we are problem solving we need almost always to try first then check and revise we can have tons of problems about this but here we can have any kind of problem as using tiles of 2x2 3x3 4x4 ft to solve a problem that asks us to use that to see which tiles can be used to cover a 9x9 floor.

First you multiply the 1x3 and then 9x4.Which will give you 3/36.Then you will simplify dividing,3 by 3 and 36 by 3.

This topic is similar to 14-1 but with metric units of capacity like if you want to know how many liters or milliliters is an object fill with you need to know how big the object is like a swimming pool there is more sense to think that is liters instead of milliliters.
