Day 3 Clip 1
In the previous clip we saw Ms. Coombs
employ the “expand” feature on graphing
calculator. In this clip, she challenges the
students to use their earlier knowledge
about distribution to go from the factored
form to the expanded form.
|
Day 3 Clip 2
Ms. Coombs continues to lead the discussion
about a situation where Graphing Calculator
has converted the function y = (x +4)(x + 6)
to the expanded form y = x2 + 10x
+ 24.

Day 3 Clip 3
Ms. Coombs asks students to make a
connection between the previously learned
distributive property and the current topic
of binomial multiplication.
|
Day 3 Clip 4
As part of the class work, Ms. Coombs has
the students think once again about finding
the zeros of a function in factored
form.

Day 3 - Clip 3
Ms. Coombs asks students to make a connection
between the previously learned distributive
property and the current topic of binomial
multiplication. Students assign the placeholders
a, b, and c from (a+b)c = ac + bc to the example
y = (x + 4)(x + 6). She leads the class through
the distributive process twice in order to write
the binomial product in the expanded, quadratic
form.
