2a + a = 18
For the equation written above, there are variables present that we first must consider. Because there are not parenthesis, or exponents to worry about (PEMDAS is not taken into consideration due to the simplicity of this equation), we must first figure out how many of the variable we have total. We see '2a' and 'a'. There is an addition sign, so we know we need to add these together. Since they are the same variable, we can simply add them together with no further complication and get '3a'. We next need to isolate the variable, or get it by itself on one side of the equation. For calculating equations with variables, we need to complete the opposite function of what is shown. For this equation we see multiplication with the variable, so we need to divide. We want to eliminate the number, but leave the variable. To do this we need to divide by 3 - this allows the 3 to be canceled out on the left side of the equation, or leaving '1a' which can be simplified to 'a.' When we do something on one side, we always have to do it on the other side. So we need to do 18 divided by 3, which gives us 6. Now our solved equation reads, a= 6. This gives us the value of the variable 'a' to be 6. We can double check our work by plugging in the number 6 to our original equation. 2(6) + 6 = 18 12 + 6 = 18 18 = 18 Since we are left with 18=18, we know solved our equation correctly.
How are organisms classified and what can you use to remember these classifications?
Organisms are classified into taxonomic rank. These are, in order from most general to specific, Kingdom, Phylum, Class, Order, Family, Genus, Species. Mnemonic devices can be used to help remember the order. An example is: King Phillip Came Over For Great Spaghetti. Using this device will be an easy way to remember the names as well as order of rank from most broad to most specific.
Differentiated instruction is very important in education today. When face with a class of 20 students, how do you cater to the individual needs of students as well as the needs of the class as a whole in correlation with the goals of that lesson?
Catering to different students with different needs can be difficult. This is a skill that can be improved over time as well. Students need to first understand what kind of learner they are. If you haven't already, give your students a quick 'what kind of learner are you' test (can be found online) so students can first understand what they need from you. Once you know what your students need, the next step is to find work, questions and collaborative activities that fit each student. Making sure that each assignment aligns with the standards and goals is critical. Students at different levels will be able to learn the same thing based on what they personally need and how they learn bet. For example, giving a visual learner a diagram to color and label and a kinesthetic learner a skit to act out to explain the concept.
