Bell Ringer – Students reviewed rounding decimals to the tenths.
After the students checked their homework, I collected it and made sure the correct process was being used to solve the proportions and to set up and solve the word problems. Some students had incorrectly graded their work. I cautioned the students about honesty in grading.
The class work today was additional practice on solving proportions and word problems. This was turned in at the end of the period. For those who did not finish, they had extra time in advisory and turned in the work at 3:00.
We will review on Tuesday for a Test on Wednesday. The test will assess the following items: writing percents as decimals, writing percents as fractions, using the fraction method to find the percent of a number, using the decimal method for finding the percent of a number, proportions and proportion word problems.
All students MUST have their own basic 4 function calculator on Tuesday. Many students have been unable to complete their assignments in a timely manner because they do not have a calculator.
Solving Proportions Notes and HW
Remember to write a complete sentence with each word problem!

Cross Products and Proportions HW
No homework tonight. Students continued to work in class on finding the percent of a number using both the fraction and decimal methods (notes given last Friday). The problems today were word problems. Students who did not finish the 18 problems should report to my room at 7:20 to finish. Remember to get a parent to sign your agenda for a pass down the hall.
Bell Ringer – Review of percents as decimals (TB page 212 problems 21-25 & 26B)
Mini lesson on writing a percent with a decimal, as a fraction in simplest form (added to bellringer page) EX. 0.25% = 0.25/100 = 25/10000 Then simplify 1/400.
Reviewed notes from Friday on Finding a percent of a number using both the fraction and decimal methods and then students completed 10 problems in class.
Videos: Math Antics Percent and Percent of a Number. Practice Problems in class on finding the percent of a number (part of an amount) using both the decimal and the fraction methods. Notes Feb 5, 2016
No Written Homework. Continue to review changing from a percent to a fraction and a decimal.
No homework tonight. We played Kahoot with a focus on changing between fractions, percents and decimals. These skills will be used tomorrow when we work on finding a percent of a number (part of an amount).
Mrs. Burdett was with her Scholars Bowl Team at the Shelby County Tournament today.
The ratio test part 2 was today. After the test, students completed a worksheet that reviewed the prior skills of changing between percents, decimals and fractions. This should be completed for homework. Changing Percents to Decimals and Fractions
We will use these prior skills in our new lessons later this week on finding a percent of a number.
Bell Ringer Quizzes were returned today.
Ratio Test Part 2 tomorrow.
Review for test – Textbook page 189 problems 18-24 and Page 191 Problems 30-37. This reviewed Unit Rates and Equivalent Ratios. The third section on the test is Using Unit rates to complete Conversions by Dimensional Analysis. I did not give additional practice on this section since it has been our most recent Homework assignments.
We took another bell ringer quiz today on Simplifying fractions before you multiply.
After checking the homework, students practiced using dimensional analysis again by working on TB page 790 9-24. We will check this tomorrow in class.
The Ratio Test Part 2 will be on Wednesday instead of Tuesday. Students will review in class tomorrow. Please see last weeks post about details on the test.
