Algebra I SOLs that
need to be Emphasized
Note: The sections in Bold and are underlined represent SOL
topics. The red pinpoints a specific SOL
strand that was identified as a division weakness. Underneath is the
URL link and a brief description of an activity that will enhance this
objective.
Expressions and Operations
http://matti.usu.edu/nlvm/nav/frames_asid_201_g_4_t_2.html?open=instructions
This site helps reinforce solving equations by using the “hands on equations” idea. It presents several types of different equations such as variables on both sides and two step.
Exponents
(A10)
http://www.gomath.com/exercises/exponents.php
In this site, students can use the exponent rules that we discuss. The only problem is that it is not set up to work with the coefficient. CD students may use as a review.
http://www.ohaganbooks.com/StudentSite/tut_alg_review/framesA_2.html
Students can review interactively with the questions given.
Multiply
and dividing a monomial and a polynomial (A11)
http://matti.usu.edu/nlvm/nav/frames_asid_189_g_4_t_2.html?open=activities
In this lesson students will explore the objectives of factoring, and multiplying monomials, polynomials with algebra blocks.
Model of
Monomial (A10)
http://curry.edschool.virginia.edu/k12/algebra/activities/alg1_virtualtiles.html
Teachers will need to go to this site and download the program. Once downloaded, students can add, multiply or make equations. A great way to add flavor to a lesson. The download does not take a lot of time and it automatically sets up when completed.
Factoring
(A12)
This site allows you to put in a factor problem and it gives you the answer. You can factor, GCF, as well as factor completely. This calcualtor also tells you if the polynomial is prime.
Determine
the
·
domain,
given its graph (A5, A16)
·
range
for points on a graph (A5, A16)
·
range
given its domain (A5, A16)
http://matti.usu.edu/nlvm/nav/frames_asid_191_g_4_t_2.html
Students can use the function machine to determine the range. Very easy to use. Only problem is that it does not use negative numbers for a domain.

Topic #2 and
#3 deals with function table. It gives a different perspective on the
domain, and range by allowing students to plug in the values. Notes also provided.
Direct
variation (A18)
http://www.mhhe.com/math/devmath/aleks/wt-ia/student/olc/graphics/author_ed/chp5sec24.htm
Students get a good explanation of the constant of variation as well as a graph that demonstrates how direct variation. There are also a few questions students can answer regarding the constant of variation. Can also experiment by substitution for the k and y.
http://www.bbc.co.uk/scotland/education/bitesize/mathsI/algebra_gen/direct_variation_rev1.shtml
A better site
that gives more examples of direct variation. It gives a couple of
problems similar to SOL direct variation questions.
Identify a
set of ordered pairs that does not represent a function (A5, A16)
http://curry.edschool.virginia.edu/k12/algebra/activities/alg1_tobelinear.html
This reasonably short (1 day) project is a self-contained exploration of the application of the line of best fit. Students analyze their own cause and effect relationships and consider whether the data can benefit from a linear interpretation. Step by step instructions are provided at this site.
Solve
problem given a formula (A2)
Calculate a
zero of a given function
In this site,
teachers get a chance to interact with a TI-83 graphing calculator. It gives the step by step directions on how
to use the graphing calculator to find the zero of a function. Can be used as a reference.

A cool game for review. Choose level 2 and 3 and not only do you have to name the coordinates, but you must also identify the line.
·
several
graphs on the same grid (A6, A7, A8)
http://terragon.com/tKobrien/algebra/
Click
on the link and it will take you to a new window. Once here, click on the GRAPH IT tab at the
top. Students can teachers will be able
to put on several graphs at one time. An excellent tool for teaching or checking HW.
Determine
the slope of a line given the
·
two
points (A6, A7, A8)
http://www.teacherlink.org/content/math/activities/em-slope/
This
is a link to the site where students can actively find the slope between two
points.
·
line
(A6, A7, A8)
http://www.bbc.co.uk/education/mathsfile/shockwave/games/planethop.html
Students must find
the slope through the points given in the problem
http://terragon.com/tKobrien/algebra/
Go to topics (#4, #5,
#6, #7, #8) Another
great interactive site with good notes.
Systems of
Equations (A9)
http://terragon.com/tKobrien/algebra/
Go to topic #12. A nice place to finish up a
lesson.
Quadratic
Equations (A14, A15)
A one stop site. This place gives you not only regular factoring, but solving for the quadratic equation as well. Students can solve the quadratic equation, use the quadratic formula and complete the square. It also has a place where Algebra II students can find all the things in a parabola.
http://hsc.csu.edu.au/maths/general/pre/data_analysis/da3/
Finally, a place where you can learn and input data at the same place. These two sites contain a great tutorial and then you go to the other site where students can input their data for their own box – n – whisker.
Scatterplot Supplement (A5, A16)
