To solve this problem we need to use the PEMDAS method. You need to solve the problem in this order 1. Parenthesis 2. Exponents 3. Multiply or Divide 4. Addition or Subtraction. If you have more than operation per step you solve left to right. 5+(6/2)-8 First we need to solve what is inside the parenthesis 5+3-8 We skipped step 2 because we did not have any exponents. The next step is to do the addition and subtraction left to right. So first we solve 5+3 8-8 Next we move on to 8-8 which equals 0 0 The answer is zero
65 students are going on a field trip. Each bus holds ten students. How many buses do they need so that every student can go on the field trip?
You need 7 buses. One way to solve this problem would be to model it. Begin by grouping 65 objects into groups of 10. Each group of ten represents one bus. When you finish grouping you have 6 groups or buses and five remaining. Given the stituation, you need to round up to 7 because all students need to go on the field trip and it is okay to have a bus that is not completely full.
What are some ways to incorporate reading and writing across the curiculum?
One way to incorporate reading in every subject is to have students to read and analyze articles about the subject. For example if you are learning about the Pythagorean Theorem, Have the students read an article Pythagorus. Another way is to have students write when ever they can. In a science lesson you can have students write a paragraph about observation having they write as detailed as they can.
