EE.2c - Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole number exponents, in the conventional order when there are no parentheses to specify a particular order (order of operations).
warm-up
Pick 4 - Evaluate the numerical expressions using GEMDAS
mini lesson - independent work/share out/discussion

b) 5am
c) 10(m + 2) + m squared
a) 2n + 3a
b) 5am
c) 10(m + 2) + m squared
team challenge
Distance to School
Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains. Let d be the distance in miles from a student's home to the school. Write two different expressions that represent how far a student travels by bike in a four week period if there is one rainy day each week.
