Division

Learning Intention: Students  will learn to organize items into groups/sets based on a common characteristic such as size, color, shape, or texture, how to sort items by separating a group of items into two groups, and develop an understanding of equal shares by actively participating in one-to-one distribution of objects to person, objects to objects, and objects to available space.

Success Criteria:  Students will be successful when they can divide by 1, 2, 3, 4, 5, and/or 10.

Essential Questions:
- How can I make equal groups from this one large group?
- How do I know this is a fair share?
- What is the product?
- What are the parts of division problem?
- What model can I use to help me solve this division problem?
- How can I solve this division problem using objects?
- How can I solve this division problem using a calculator?

Standards Covered

EE.6.NS.2.   Apply the concept of fair share and equal shares to divide.

EE.7.NS.2.b.   Solve division problems with divisors up to five and also with a divisor of 10 without remainders.
Division is a sharing operation where objects are shared (or divided) into a number of groups of equal number.

Division is splitting into equal parts or groups.

Division undoes multiplication.

Vocabulary

divide - to determine how many times one number is contained in another number.

dividend -  the number to be divided. 

divisor - dividend ÷ divisor = quotient   Example: in 12 ÷ 3 = 4, 3 is the divisor.  Divisor can also mean : a number that divides an integer exactly (no remainder). 

equal groups - collections of items formed by sorting the total number of items into piles that have exactly the same number of items in each pile.

factor -  divides a number completely without leaving any remainder.
​For example : 30 ÷ 6 = 5, and there is no remainder.  So we can say that 5 and 6 are the factors of 30.

quotient - is the result of division.

repeated subtraction - a method of subtracting the equal number of items from a larger group.

Repeated Subtraction Strategy

Repeated subtraction is a method of subtracting the equal number of items from a larger group. It is also known as division. If the same number is repeatedly subtracted from another larger number until the remainder is zero or a number smaller than the number being subtracted, we can write that in the form of division.
