Physical Activity Grab one sheet of paper and put your name on the top When I say “go,” get up and go to a green fraction hanging on the wall. You will convert the fraction in green to a decimal. Then, you will find your answer (in red) located around the room. Go to the problem where your answer is located. Convert the fraction in green, and then go find your answer in red. Repeat.

Insert Lesson Title Here Vocabulary Order of Operations –Take one minute to write down your steps for getting ready for school in the morning or going to bed at night. Definition: the order in which operations should be done
6
Course 2 When simplifying a numerical expression, rules must be followed so that everyone gets the same answer. That is why mathematicians have agreed upon the order of operations.
7
ORDER OF OPERATIONS 1. P Perform operations within grouping symbols. 2. E Evaluate powers. 3. MD Multiply and divide in order from left to right. 4. AS Add and subtract in order from left to right. PEMDAS

Insert Lesson Title Here Course 2 WITH WORDS Jill is learning vocabulary words for a test. From the list, she already knew 30 words. She is learning 4 new words a day for 3 days each week. Evaluate the expression 3 · 4 · 7 + 30 to find out how many words will she know at the end of seven weeks? DayWords Initially30 Day 14 Day 24 Day 34 3 · 4 · 7 + 30 12 · 7 + 30 84 + 30 114 Multiply. Jill will know 114 words from the list at the end of 7 weeks.
