Tape measure 101
Six question Kahoot based on the various measurement lines and uses of a tape measure to determine prior knowledge
Anonymous answer of kahoot questions to see who knows what a tape measure is and why it is important
2 Direct Instruction
Have students use tape measure to measure five items in the room based on their prior knowledge of the tape measure.
Choose five items to measure and make your best guess. Write down your answers
3 Guided Instruction
Explain each line in an inch from 1/16th to 1/8th,1/4,1/2
Draw inch out for students review
Show edmodo with construction mistakes that could have been solved with proper measuring.
Draw your own inch and label it
4 Independent Instruction
Re-measure the same five items as before use proper measurement
Re-measure the five items and write down correct measurement
5 Wrap up

Key Standards Supported
Write a function that describes a relationship between two quantities.
Determine an explicit expression, a recursive process, or steps for calculation from a context.
Combine standard function types using arithmetic operations. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model.
(+) Compose functions. For example, if T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.
Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.
Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
Find inverse functions.
Solve an equation of the form f(x) = c for a simple function f that has an inverse and write an expression for the inverse. For example, f(x) =2 x3 or f(x) = (x+1)/(x–1) for x ≠ 1.
(+) Verify by composition that one function is the inverse of another.
(+) Read values of an inverse function from a graph or a table, given that the function has an inverse.
(+) Produce an invertible function from a non-invertible function by restricting the domain.
(+) Understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents.
