Students were in the computer lab today working with Cognitive Tutor.

They should be practicing / studying tonight for assessments tomorrow!  See earlier posts for more information, examples.

CP 1st & 5th Period 1/31/11 – 2/4/2011

Monday – Cognitive Tutor Lab
What Goes Up Must Come Down – Quadratics Unit Learning Targets
1. Recognize tables , graphs  and equations  of quadratic functions.
2. Identify the domain , range  , intercepts , maximum  and minimum  of a quadratic function.
3. Graph a parabola by hand using axis of symmetry, vertex, y-intercept & reflection point .
4. Predict how the changes of an equation will affect the graph of the equation.
5. Solve a quadratic equation using the Quadratic Formula .
6. Apply quadratic concepts to real-life problems (i.e. vertical motion formula).

Tuesday – Assessment Quadratics (Targets #6, #3, #2, #5) – Similar to Pumpkin Launch post from Friday.  Students not achieving at least 80% will work with me individually in the lab on Thursday.
Complete our ABC groups for the transformations grid-worksheets (Target #4) – return to our home groups, share examples, discuss as whole class. HW assignment (from board) due Wednesday.
Wednesday – Formative Assessment on Wednesday based on HW & immediate self-assess. (one on one in lab Thursday, if needed)
More application problems on variety of real-life situations – Target #6
Thursday – Cognitive Tutor Lab
Friday – What Goes Up Must Come Down – Summative Assessment

Algebra I 2nd, 3rd, 4th Period 1/31/11 – 2/4/2011

Monday – Cognitive Tutor Lab
Scotland Yards – Revisiting Equations & Inequalities Learning Targets
1. Demonstrate how different sets of numbers are related □.
2. Solve equations that involve:
□ CLT, □ Distributive Property, □ VOBS, □ Complicated & □ Special situations.
3. Solve real-world problems by solving equations □.
4. Identify number properties □.
5. Use number properties to justify a step to simplify an expression or solve an equation □.
6. Model, solve and graph inequalities □.

Tuesday – Assessment Solving Equations & Inequalities (Targets #2, 3, 5, 6).
See Friday post for examples / practice problems/online resources.
Questions students can ask themselves to “walk through” basic equations:
• Do I have (parentheses)? Then distribute.
• Do I have “like terms” on the same side together? Then combine like terms (CLT).
• Do I have variables on both sides of equation / inequality? Move them to one side…good idea to get rid of the smaller term.
• 2-step Equation? Add or Subtract the constant (just the number); Multiply or Divide by the variables coefficient (# in front of variable).
Students not achieving at least 80% … Teacher Action – I will work with them individually in the lab on Thursday.
Wednesday – Complete work with Number Sets, Number Properties & Closure…see Student unit organizer.
Thursday – Cognitive Tutor Lab (individual instruction with students based Tuesday assessment)
Friday – Tuesday Assessment returned / Reassess & Quiz (formative assessment) on Targets #1, 4.

Looking Ahead…next unit “Down on the Farm” Relations & Functions

Cognitive Tutor @ home

Two days each week, students spend their classtime in the computer lab working on an online curriculum from Carnegie Learning called Cognitive Tutor.  Students also have access to this program at home.  Usually, the only update with your home computers is with Java.

To access these lessons, students should go to our school website www.russellcountyhigh.com go to the drop down menu, links and events and locate Carnegie Learning.

They know the rest.

Just a reminder that students will receive credit for ALL work completed at home on Cognitive Tutor.

There are Help & Hint buttons, as well as Lessons (read the blue boxes) and interactive examples.

Please take a few minutes and watch your student go through some of the problems.  Ask them to explain the green / gold bars.

After talking with a few parents, I have realized they did not know about this wonderful opportunity to work at home.

Cool Math – A GREAT resource for students and Parents

Parents often ask for resources they can use to help their students at home.  Sometimes, just have some extra problems to work and a way of checking student work is hard to find for parent.   Let me suggest Cool Math.  Once there, you should look on the left side for the appropriate subject for you student.  Most of our topics in the DOCK can be found by clicking the purple Algebra flag.  There are some great articles, but most of you will want to scroll down to the

Algebra Help Lesson Topics

In this grid, you will find units with examples and descriptions of how to solve problems.

Following some of the lessons, you may see Crunch Some”- you can generate practice problems, work them out on your own paper, then check your solution.

Monday is a “lab day” so students will continue working on Cognitive Tutor.

Next day back in class (I say this because, who knows with weather in Kentucky!) –

          Algebra I will have a test over solving equations.  Students have a review with answers…they can use them to practice for their upcoming assessment!

Suggested units to review from Cool Math are

          Solving Equations – Focus on lessons 4 & 5,

then Crunch Some

          Solving Inequalities – Focus on lessons 4 & 5,

 then Crunch Some

 

            CP Algebra I – will have an assessment very similar to their “Pumpkin” problems today in class; using vertical motion formula, finding axis of symmetry, vertex (max or min?) and x-intercepts using Quadratic Formula.  Don’t forget to complete your 5-Problem HW assignment!

          Suggested units to review from Cool Math are

          Solving Quadratic Equations – Lesson 5 using Quadratic Formula

          Graphing Quadratic Equations (Parabolas)  – Lessons 1 – 6.
