Math And E.L.A exams

In E.la we are starting to study for exams. First we did a schonal test out of 100. After you corrected it, you had to ffigure out what your mark was. Mr.Routledge told us where we were before and we are now. Most people went up. Also 20 of those 100 words are going to be one the test.

In math we started studying for exams. The first thing we did was mental math. You had to number your paper 1-10 and answer questions. We also did the no calculators part, witch might take some people quite a long time. It has questions like 432.89 x 523.80. Then we started some of the third part that you can use calculators in.

Angles

In math we are reviewing for an exam. One of the things we learned about was angles. An acute angle is less than 90 degrees, an obtuse angle is 90 degrees to 180 degrees. a right angle is exactly 90 degrees and a reflex angle is 180 to 360 degrees.

Math

Today we learned about mean,median and mode.

Mean is an average group of numbers. to get mean you have to add the numbers together, divide the total for the numbers by how many numbers there is all together.

Median is a group of numbers that is ordered greatest to largest.

Mode is a number that appears most often in a group of numbers.

Math

Yesterday in math we learned about range, median, mode, mean.

Mean- the average number in a group of numbers. To find it, add all the numbers together and then divide by the amount of numbers.
Mode- the number that occurs the most. You just have to find the number that appears the most. It is fine to have more than one number.
Median- the number that is in the middle of a group of number that are arranged in order. If there are two in the middle, add them together and divide them by 2.
Range-the difference between the lowest and highest numbers.

numbers in word form

today in math class we reviewed unit 1 math wich is the different forms for numbers. there is standard, exponential, word form, and expanded.

ex: 25
standard- 25
exponential-52
word form- twenty five
expanded form- 20+5=25

Circle Graphs

Today in math we learned how to make circle graphs. To make a circle graph you have to know how many degrees of the angle each percent is. Example:
25% of 360 degrees
0.25X360=90 degrees
Then you make a 90 degree angle on your graph and label it 25%.

Symmetry

Today we learned about lines of symmetry and planes of symmetry. Lines of symmetry divide a 2 dimensional objects into 2 equal parts. Each part is a reflection of the other. Planes of symmetry divide a 3 dimensional object into 2 equal parts. Each part is also a reflection of the other.

Translations

In math we are learning about translations. A translation is where you have plotted a triangle on a coordinate plane, and then after you plot that the translation may say (3,-2) and you would move the dots on the triangle to the right three, and down two.

Translations

In math we are learning translations. On a coordinate plain if the translation is (-5, 8) then you move your dot five places to the left and eight places up.

Math

In math we are learning about translations. Translations are done on a coordinate plane. A coordinate plane is a vertical line and a horizontal line that are intersected at zero. The lines have negative and positive numbers. When you translate something it doesn't change it stays the same shape, size and figure. You just move it from left to right and up or down. Here are some examples:

This is how a translation is written as a question:

A(3,4) , B(1,1) , C(4,1)

Translation (-4,-2)

Here are four examples of translations in real life:

Washing windows, puck sliding on the ice, the belt on a treadmill, and a Frisbee gliding in the air.

Math Test

Today we had a math test on measurement. Some things that were covered were circumference, angles, and triangles.

To find the circumference of a circle, multiply the diameter ( the distance across the middle of the circle) by pi (3.14).

To find the area of a circle, multiply pi by the radius ( the distance from the middle of the circle to the edge) squared.

Triangles

Today in math we did a sheet on angles of the interior of a triangle. Some things that we learned were:

• The sum of the angles must add up to 180 degrees .


• An equilateral triangle must have 60 degrees for all the angles. Because the sides are equal, the angles must be equal.

Triangles

In math we learned about equalatural, scalene and isoceles triangles. An equalateral triangle has three sides even lengthed, a scalene triangle has no sides equal lengthed and an isoceles triangle has two sides the same length.

classifying triangles

Today in math we learned about triangles. You classify triangles by the lengths of their sides.

Equilateral triangle = has three sides of the same length.
Scalene triangle = has no sides of the same length.
Isosceles triangle = has two sides of the same length.

You classify triangles by the measures of their angles.

Acute triangle = has three acute angles ( less then 90 degrees).
Right triangle = has one right angle (90 degrees).
Obtuse triangle = has one abuse angle ( more than 90 degrees).

Triangles

Today in math, we learned about triangles. You can describe triangles by the angles or the length of the sides. The different types of triangles are:

Right- has one right angle
Obtuse- has one obtuse angle
Acute- all the angles are acute
Scalene- the sides are all different lengths
Isosceles- two of the sides are the same length
Equilateral- all the sides are the same length

Math

In math today we learned about eguilateral, isoselous, and scalene triangles. An equilateral triangle is a traingle that has 3 equal sides. An isoselous triangle is a triangle with 2 equal sides and an opposite side. An scalene triangle has 3 different sides, none of them are the same.

Examples:

1. If a triangle has sides that are all 9cm. It is a equilateral triangle because all the sides are the same.

2. If you have a triangle with a side that is 3cm, 5cm and 7cm. It is an scalene triangle because none of the sides are the same.

3. If you have a triangle with sides that are 4cm, 4cm, and 2cm. It is a isoselous triangle because 2 of the sides are the same and one of them is different.

Math

Today in math we did a sheet on how to find the measurements of angles without measuring them with a protractor. To do this we know that alternate angles are equal, corresponding angles are equal, and that co-interior and co-exterior angles are supplementary. Supplementary means that if you put two or more angles together they equal 180 degrees.

Intersecting and perpendicular lines

Today in Math we learned about intersecting and perpendicular lines. Intersecting lines are lines that cross. Perpendicular lines cross or meet and are right angles. Intersecting and perpendicular lines are alike? They are alike because they both cross each other. They are different because perpendicular lines have to be a right angle while intersecting lines can be any angle.

Angles

Today we did more work on classifying angles. The different types of angles are:
1. acute- measures less than 90 degrees
2. obtuse- measures between 90 and 180 degrees
3. straight line- measure 180 degrees
4. reflex- measures between 180 and 360 degrees
5. supplementary- when the sum of 2 or more angles is 180 degrees
6. complimentary- when the sum of 2 or more angles is 90 degrees
7. right angle- measures exactly 90 degrees.

Angles

Today in math we learned more about angles. Angles are named with 3 letters and the letter in the middle is the vertex (meeting point of the lines). Ex: if an angle has the letters A, B, C, and the vertex is B, the angle would be angle A, B, C or
