Secret Chambers by Joe.B. and Bryan

Every inch in a ruler has secret chambers.  There are sixteen chambers in a inch.  You measure how many sections of those sixteen parts your now measure and mark for your answer.  You might have 1 3/16. That means 1 inch, and 3 parts of the 16. 

Some times you may see only 8 of the parts or secret chambers.  8 equal parts in the inch.  You may measure 1 and 2/8. That means 1 inche and 2 of the 8 parts is the length.  You can simplify this and also see that it would also be 1 1/4.  That means  1 inch and 1 of the 4 total sections is the length. 

When you measure, you need to find the whole number first, and then the "parts of the inch" which is a fraction.  And we all know that decimals and fractions are a "part of a whole."




A ruler is an instrument used in geometry.

Adding and Subtracting Fractions By Cassie

Adding and subtracting fractions can be very fun and easy.   What you do is you look at the denominaters  And if there the same then you just leave them the same then you add the numeraters.  Then you ask yourself if you have to change anything. (is it a improper fraction or does it need to be simplified..."how low can you go?"

  Subtracting fractions is almost the same but you subtract the numeraters instead of adding the numeraters.

  You can add or subtract fractions by drawing a candy bar or pizza to see the number of pieces.
You can also use a fraction strip to compare fractions.
Learning about fractions is very fun.   I  like learning about fractions do you?

Multiplication by Joe M.

Multiplication is when you put groups together. For example, you might have 4 groups 3 cookies.  The multiplication sentence would be 4 x 3.   So 3 cookies + 3 cookies + 3 cookies + 3 cookies =
12 cookies. 
The is above black dots is an array.   The multiplication sentence is  7  x   4  = 28
The numbers you multiply is called a factors.
The answer when you multiply is the product.
Do you like multiplication?

An angle is a shape formed by two rays diverging from a common point called the vertex.  There a many angles.
Here are the names of some:
Acute Angle:  measures less than 90 degrees (see above)
Right angle: measures 90 degrees
Obtuse angle: measures between 90 degreesand 180
Complementary angle: have measurements with a sum of 90 degrees
Straight angle: measures 180 degrees
Supplementary angles: have measurements with a sum of 180 degrees
