Chapter 12 GoMath

In chapter 12 we will be learning about both customary and metric units of length, weight/mass, and liquid volume.  We will also find elapsed time and learn to compute with mixed measures.  There are eleven sections in this chapter.

2.  decimeter;  A metric unit for measuring length or distance
3.  fluid ounce;  The smallest customary unit for measuring liquid volume.
4.  gallon;  A customary unit used to measure liquid volume.
5.  half gallon;  A customary unit used to measure liquid volume.
6.  line plot;  A graph that shows the frequency of data along a number line.

8.  millimeter;  A metric unit used to measure length
9.  ounce;  A customary unit used to measure weight.
10.  pint;  A customary unit used to measure liquid volume.
11.  pound;  A customary unit used to measure weight.
12.  quart; A customary unit used to measure liquid volume.
13.  second;  A small unit of time.
14.  ton;  A customary unit used to measure weight.
15.  benchmark measurement;  A reference which you can measure by.
     



 

GoMath Chapter 13

We are skipping chapter 12 for now and moving on to chapter 13.  We will come back to 12 after chapter 13.  In chapter 13 we will be learning about perimeter and area.  We will explore the concept that area is a measure of how many square units cover a flat surface. We will also learn the formula for finding the area of a rectangle.

Important Chapter Vocabulary
1.  Area;  The number of square units needed to cover a flat surface.
2.  Base;  Any side of a two-dimensional figure
3.  Formula;  A set of symbols that expresses a mathematical rule.
4.  Height;  The measure of a perpendicular from the base to the top of a two-dimensional figure.
5.  Perimeter;  The distance around a figure.
6.  Square Unit;  A unit of area with dimensions of 1 unit x 1 unit.

Formula for perimeter of a rectangle;   (2 x length) + (2 x width) =

                                                      
                                                          (2 x 7) + (2 x 3) = ?
                                                             14   +   6 =   20
                                                               perimeter = 20

Formula for perimeter of a square;  (4 x one side) =

                                                        
                                                                (4 x 4) = 16 
                                                             perimeter = 16

Formula for area;  (base x height)

                                   
                                
                                            (7 units x 4 units) = 28 square units
                                                         area = 28 square units 
                                                

GoMath Chapter 11

In our geometry unit we are moving on to learning more about angles and angle measures.  We will also learn to use a protractor to measure and draw angles.  There are five sections in this chapter.

Important Chapter Vocabulary
1.  Clockwise;  In the same direction in which the hands of a clock move.
2.  Counterclockwise; In the opposite direction in which the hands of a clock move.
3.  Degree;  The unit used for measuring angles.
4.  Protractor;  A tool used for measuring the size of an angle.

PROTRACTORS

GoMath Chapter 10

Throughout the next few weeks, we will be studying two-dimensional figures.  The students will use definitions to identify and describe characteristics of these figures.  Our homework will have identifying triangles and quadrilaterals.  This chapter has seven sections.

Important Chapter Vocabulary
1.  Acute Triangle;  A triangle with three acute angles. (less than 90 degrees)
2.  Line Segment;  A part of a line that includes two points, called endpoints, and the points between them.
3.  Obtuse Triangle;  A triangle with one obtuse angle.  (larger than 90 degrees)
4.  Ray;  A part of a line, with one endpoint, that is straight and continues in one direction.
5.  Right Triangle;  A triangle with one right angle (90 degrees) and two acute angles.

GoMath Chapter 9

Our class will relate both fractions and money to place value and will learn how to rename fractions as decimals.  We will also add fractional parts of 10 and 100 and compare decimals through hundredths.  There are seven sections in this chapter.

Important Chapter Vocabulary
1.  Decimal;  A number with one or more digits to the right of the decimal point.
2.  Decimal Point;  A symbol used to separate dollars from cents in a money amount and to separate the ones and the tenths place in a decimal.
3.  Equivalent Decimals;  Two or more decimals that name the same amount.
4.  Hundredth;  One of one hundred equal parts.
5.  Tenth;  One of ten equal parts.

8/10   =  0.8

                                                                 

GoMath Chapter 8

In this chapter, the students will learn to multiply fractions and mixed numbers by whole numbers. We will learn to write a fraction as a product of a whole number and a unit fraction, and to find multiples of unit fractions. There are five sections in this chapter.

Important Chapter Vocabulary
1.  Factor;  A number that is multiplied by another number to find a product.
2.  Fraction;  A number that names part of a whole or part of a group.
3.  Identity Property of Multiplication;  The property that states the product of any number and 1 is that number.
4.  Multiple;  The product of two counting numbers.
5.  Product;  The answer to a multiplication problem.
6.  Unit Fraction;  A fraction that has one as the numerator.


                           
                                   2  x  5/8   =   10/8  or  1 2/8
