### GoMath Chapter 4

Our class will be learning how to model division, and use the division algorithm to divide up to 3-digit dividends by 1-digit divisors.  The class will learn different methods to divide, including using models, repeated subtraction, and the standard division algorithm.  We will also learn to divide with remainders.
Our homework will provide practice modeling division and using the division algorithm.  There are twelve sections in this chapter.

Important Chapter Vocabulary:
1.  Compatible Mumbers;  Numbers that are easy to compute mentally.
2.  Multiple;  A number that is the product of a given number and a counting number.
3.  Partial Quotient;  A method of dividing in which multiples of the divisor are subtracted from the dividend and then the quotients are added together.
4.  Remainder;  The amount left over when a number cannot be divided equally.
5.  Dividend;  The number that is to be divided in a division problem.
6.  Divisor;  The number that divides the dividend.

### Chapter 3 GoMath

Our class, during the next few weeks, will be learning to multiply by 2-digit whole numbers.  We will also learn how to describe the reasonableness of an estimate.
The homework will provide practice with estimation and multiplication of numbers with more than 1 digit. There are seven sections in this chapter.

Important Chapter Vocabulary:
1.  Compatible Numbers;  Numbers that are easy to compute with mentally.
2.  Associative Property of Multiplication;  The property that states that when the grouping of factors is changed, the product remains the same.
3.  Commutative Property of Multiplication;  The property that states when the order of two factors is changed, the product remains the same.
4.  Estimate;  To find an answer that is close to the exact amount.
5.  Partial Product;  A method of multiplying in which the ones, tens, hundreds, and so on are multiplied separately and then the products are added together.
6.  Product;  The answer in a multiplication problem.
7.  Regroup;  To exchange amounts of equal value to rename a number.
