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.

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.

GoMath Chapter 7

Our class will be learning how to add and subtract fractions and mixed numbers over the next few weeks.  First, we will use models to find the sums or the differences.  Then we will record equations to match our models.  Finally, we will add and subtract without using models.  Our homework will be practice adding and subtracting fractions with and without models.  There are ten sections in this chapter.

 Important Chapter Vocabulary 
1.  Mixed Number; An amount given as a whole number and a fraction.
2.  Unit Fraction;  A fraction that has a numerator of one.
3.  Associative Property of Addition;  The property that states that when the grouping of addends is changed, the sum is the same.
4.  Commutative Property of Addition;  The property that states that when the order of two or more addends is changed, the sum is the same. 
5.  Denominator;  The part of the fraction below the line, which tells how many equal parts there are in the whole or in a group.
6.  Fraction;  A number that names part of a whole or part of a group
7.  Numerator;  The part of a fraction above the line, which tells how many parts are being counted.
8.  Simplest Form;  A fraction in which the numerator and denominator have only 1 as a common factor.
