This is a habit that cannot bloom from one day to the next, but instead requires constant reminders. Substitution of negative numbers and operations with fractions are two skills affecting mastery within this question. Again, students are also not showing all of the steps when simplifying. The third question is all about the number line.
I show students the distance between the two temperatures in question and push them to draw and label the number lines on their own. I am watching out for students who require remediation in more basic skills such as identifying integers on the number line, or drawing number lines properly. There are a few students drawing number lines with positive numbers to the left and negatives to the right. We review the answers and strategies for each question in the last 3 — 4 minutes of this class, allowing students more time to explain how they solved.
All students return to their seats and receive class notes. I decided to include a lot of content to save time on copying notes. This is a review lesson including prime factorization and factor trees. I am taking a day to review this strategy to address the factoring component of this unit. We begin by defining prime factorization, the tree method, and negative numbers. I share a question from a sample CCSS document about volume and missing dimensions.
I explain to students that this is also an example of the kinds of word problems that need mastery from most of the grade, based on their mock and unit assessments data. I use the words factor and multiple many times, asking different students each time to identify each in a list of numbers or to tell me the difference between the two.
The difference between these two words is a common misconception in this grade each year. The same can be said of the words prime and composite. There is a ton of vocabulary to practice today so I push myself to let students do most of the talking, encouraging with questions only.
I do model what the tree method looks like in the first example and in the negative number example. Students can ask questions, and my help will guide them through their own notes to encourage their use. If is divided into two sections: Students must work with their neighbors to complete the questions. They freeze up and are afraid to take any steps, exclaiming defeat rather quickly. The skills section of this class work does not have to be completed second.
Students may begin with this section to get ready for the task problem. After 10 minutes, I will stop class to allow 3 — 4 minutes of questions about the task problem. Then, students will be allowed to continue working together after also being advised that this assignment will be collected for a grade. Work must be shown. Any students allowed to work in booths will be asked to return to their seats. They will be given the remainder of class time to work silently on completing this task.
I will be distributing homework during this time. Sign Up Log In. Unit 4 Unit 1: Operations with Rational Numbers Unit 3: One of the basic concepts of mathematics is expressing numbers in terms of smaller numbers, whether by addition seven is the sum of three and four , multiplication 12 is the product of three and four , or exponentiation 81 is three to the fourth power.
We often find it useful to break a number down into smaller numbers. Given a number, we call any number that divides evenly into it one of its factors , where dividing evenly means there is no remainder. For example, the factors of 12 are 1, 2, 3, 4, 6 and 12, because 12 can be divided by each of these with no remainder.
So what is prime factorization? Recall that a prime number is any whole number that is, a positive integer that can only be divided by itself and one; every whole number that is not prime is composite , with the exception of one itself, which is neither prime nor composite. The prime factors of a number are just those factors that happen to be prime; the fundamental theorem of arithmetic states that every positive integer can be uniquely factored into a set of prime numbers, which we call the prime factorization.
Twelve is the product of three and four, three is prime, four is the product of two and two, and two is prime. How about another example? Prime factors are used frequently in advanced mathematics.
For example, cryptographic software often depends on the difficulty of factoring very large numbers. Knowing how to find the prime factorization also makes it easy to do a number of other things, such as finding the greatest common factor, finding the least common multiple or simplifying roots. Can you find the prime factorization of each of these numbers? The answers are below. What is the prime factorization of 21?
