IEP Strength: “In math, John does well at solving 1-2 step algebraic problems, and can be successful with multi-step problems when provided with similar examples to work from.” IEP Need: “John will often become lost on long multi-step mathematical processes and will need to be guided back
retaining the concepts and processes from one class period to the next.” IEP Goal: “When given a worksheet of multi-step equations/inequalities with one variable, the student will independently solve the equation/inequality with 80% accuracy.”
problems Sample Problem:
The problem is the amount of expected work for “one” problem:
FACTOR Find a common denominator and multiply Solve the NUMERATOR Distribute Combine like terms Get all terms to one side, to solve a quadratic FACTOR Solve a 2-step equation (subtract, then divide) Check for extraneous solutions Skills required:
FACTOR Find a common denominator and multiply Solve the NUMERATOR Distribute Combine like terms Get all terms to one side, to solve a quadratic FACTOR Solve a 2-step equation (subtract, then divide) Check for extraneous solutions If they can’t distribute, how can you know whether or not they can solve
They won’t get that far.
Strategy #1: Break the “one” problem into many, so students can show the parts they know, and you can tell where EXACTLY they need help.

Ansley takes twice as many hours to clean the garage as her sister Betsy. When they both work together, they can clean the garage in 6 hours. How many hours would it take Betsy to clean the garage alone?
garage as her sister Betsy. (2x)
clean the garage in 6 hours.
Strategy #3: Give the form of the equation(s)
Strategy #4: Color code to map the words to the equation How many hours would it take Betsy to clean the garage alone? (x=number of hours for Betsy alone)
as her sister Betsy. (2x)
garage in 6 hours.
van and 2 buses with 29 people to go to the fair. The first grade classes at Westside Elementary rented and filled 3 vans and 4 buses with 63 people . Find the number of people in each van and in each bus. 1x + 2y = 29 3x + 4y = 63
5 = 29 – 5 = 24 students in 2 buses Answer: 5 students in each van, and 12 students in each bus
We’re not talking about this anymore: Or even this:
Now it’s more like this: So how can we teach kids to handle complex graphing?
Which is which? Why?
I can put the point (3, 5) on the graph. But where do I put (-2.7, 6.4)??
Graph dotted lines for the asymptotes. Then put points for the x and y intercepts, count “up and over” for the slope, put open circles for any holes …
x-intercept, y-intercept, asymptote, end behavior, slope, maximum, minimum, hole, open circle, domain, range, …

#1 Lots of examples #2 Discuss similarities and differences #3 Pick your battles #4 Color coding the steps #5 Have students explain to each other and the class
and not.
– Post them. Use them
– think aloud
