This week in math we'll be continuing our unit on percents by focusing on multiple ways to calculate markups/tax/tip and discount. For example - finding the total cost of an $80 jacket with a 15% discount - instead of multiplying 80 by 0.15 and subtracting the answer from 80, students will need to know that they can simply multiply 80 by 0.85. Similarly, instead of calculating 20% tip and 7.5% tax on a bill of $23.65 with multiple steps (multiplying and adding), students will be able to complete it in one step by multiplying $23.65 by 1.275. Quiz on Friday.
After a final day of project work time on Monday, students will present their genetic disorders group projects starting on Tuesday. As soon as every group has presented (this might stretch into Wednesday), I will pass out the study guide for the summative unit assessment on heredity, which will be given on Friday. Our next unit, which is on rocks and minerals, will begin with a pretest next Monday.
This week in math we will be starting our new unit on percents. We will begin with reviewing how to write percents as decimals and vice versa, and then move on to finding the percent of a number (ex. what is 37% of 54?). This concept gets extended later in the week when we begin to use proportions to solve word problems involving percents. Expect a quiz on Friday!
This week in science we will be continuing our unit on heredity. We will be tackling the standard that requires students to differentiate between sexual and asexual reproduction. The process of meiosis (sex cell division) will be taught early in the week, with an emphasis on why sex cells must be divided twice (as opposed to once during mitosis). We will then move on to the three ways that organisms can reproduce asexually and compare the DNA of their offspring with the DNA of offspring who were produced sexually. Quiz on Friday.
