We are now in the second quarter. Today was the first day. Here is a summary of where we are and what I think has been accomplished (I will also mark above what I think has been done and still needs to be done):

So far they:

"know" how to:

find output from input when given a recipe

graph from a recipe and a table

read points off graphs

find easy equations from tables

locate "slope" in the graph

"understand" rate of change in story problems.

We need to:

establish:

that lines have constant rate of change and other functions do not

slope as rate of change

where in the equation we find slope

where in the equation we find y-intercept

learn

how to write an equation from table or graph

find input from output (read off graphs, solve equations)

find equation of a line through two points (no formula given - ever)

understand

slope (fractional slope, too)

I propose that tomorrow we do hq4, talk about last homework, work on linear relationships 2 which will address 1, then have them make tables and graph following:

y=-3x+1
y=4-x^2
y=x^3-1
y=3x-4

which will further work on 1, but also start addressing 3. and 4. After that we would work on

Diane Crim suggested we play a game "read my mind" where they give me inputs, and I give them back the outputs, until someone is able to guess the rule which I use to generate the outputs. Brian added a twist where they're not supposed to just tell us a rule, but rather give both input and output instead. This allows more kids to come up with a rule instead of always having the same student do it. This is becoming a part of the class. I am soon going to modify it first by allowing only two inputs, then by not allowing 0 as an input.

I think I have done the students disservice by not being better prepared, more organized and with greater vision. We have had some awesome lessons, but I don't think I have followed through enough. In other words, seems that things are left unsaid, and sometimes disconnected. The hope is that eventually we will tie up all the lose ends. I'll try to start tomorrow.

Describing linear patterns with...

writing

pictures

numbers

graphs

equations

Infuse with statistics (scatterplot, + and - correlation, estimate values by linear extrapolation) Equivalent expressions (different procedures yield same results therefore they are equivalent)

clearing fractions

distributive property

combining like terms

dealing with variables on both sides

inverse operations

Solving equations: start backwards! give x=1 and have them come up with a complicated equation thatâ€™s equivalent to this one.

followed by the second (melting snow problem).

In the meantime, we have worked on the activity, but have not gone back to the snow melt yet. Here are some homeworks that have been assigned.
