Prime+Time

=Prime Time =  Problem-Solving Goals:
 * __Investigation 1:__**

 Problem-Solving Goals:
 * Become familiar with the factors of the numbers from 2 to 30.
 * Review multiplication and division facts.
 * Relate dividing and finding factors of a number.
 * Classify numbers as prime and composite.
 * Recognize that some numbers are rich in factors, while others have few factors.
 * Develop understanding of factors and multiples and the relationships between them.
 * Understand that some products are the result of more than one factor pair (Ex: 18 = 9 x 2 and 18 = 6x 3)
 * __Investigation 2:__**

 __**Investigation 3:**__ Problem-Solving Goals:
 * Recognize that factors come in pairs and that once one factor is found, another can also be found.
 * Visualize and represent a factor pair as the dimensions of a rectangle.
 * Determine whether a number is prime/composite, square/non-square, and even/odd based on factor pairs.
 * Develop an informal sense of what factors must be checked to be sure all the factors of a number are found.
 * Determine whether a product is even or odd based on its factors.
 * <span style="font-family: 'Comic Sans MS',cursive;">Classify numbers by their characteristics using Venn diagrams as a tool for sorting and classifying.
 * <span style="font-family: 'Comic Sans MS',cursive;">Develop understanding of factors and multiples, common factors and common multiples, and the relationship among them.

<span style="font-family: 'Comic Sans MS',cursive;"> Problem-Solving Goals:
 * <span style="font-family: 'Comic Sans MS',cursive;">Recognize situations in which finding common multiples of whole numbers is important.

 * <span style="font-family: 'Comic Sans MS',cursive;">Develop strategies for finding the least common multiple.
 * <span style="font-family: 'Comic Sans MS',cursive;">Begin to develop strategies for finding common factors.
 * <span style="font-family: 'Comic Sans MS',cursive;">Recognize situations in which finding common factors and, in particular, the greatest common factor.
 * <span style="font-family: 'Comic Sans MS',cursive;">Recognize when common factors and greatest common factors are helpful in solving problems.
 * __Investigation 4:__**

<span style="font-family: 'Comic Sans MS',cursive;">
 * <span style="font-family: 'Comic Sans MS',cursive;">Find Factorizations of numbers and then break them down into prime factorizations.
 * <span style="font-family: 'Comic Sans MS',cursive;">Understand that prime numbers are the essential multiplicative building blocks for whole numbers.
