As a Bubbe (grandmother) myself I'd answer it this way:
"Do you remember last year when it was almost your ___th birthday? One month or so before the big day we started saying that you were almost __(the next age). We estimated and to do this we rounded the number...
This is a distribution problem. Think of the 7 as something that will effect both things inside the parentheses. 7 (b + 3) = 7 times b plus 7 times 3 or 7b+21
Distribution can also happen when the parentheses come first; as in (3 - x) 4 = 12- 4x
Lines can be defined in three ways:
1) the standard form Ax + By = C
2) the slope-intercept form Y = mX + b where m is the slope of the line and b is the Y intercept
3) the point slope formula with uses a point and the slope of the line in the form Y-Y1 = m (X-X1)
Many standardized tests, including the SAT, ACT, GRE and GMAT do allow the use of a calculator, and I believe the ASVAB should too. I posed this argument to the Department of Defense in October of 2011 and an aide to the Undersecretary of the US Navy wrote back stating that it was under consideration...
Behind every man or woman who serves in the US military stands a army of people who have prepared them for their service. Parents, grandparents, aunties and uncles, teachers, coaches and yes, tutors too.
It's been my honor to serve as a tutor for some of America's finest soldiers, sailors, airpersons and marines as they prepared for their ASVAB exams and today one...
"What did you wish you knew how to do and what did you wish you had already done a few times before you went off to college?" I asked a group of 500 very successful college seniors from all across the US in 2007.
The answers were amazing!
Then I posed the same question to a group of college drop-outs and to a group of men and women in the Department of Corrections who were 25-30...
When we tutor a student they are able to get through the work at hand, and that's good.
When we academically coach a student they can tutor themselves both through the current cadre of assignments, test preparation and projects and also through all other future studies, and that is far, far better!
Academic coaching is economical; often in 4-5 sessions I can take a student to the point...
The US Department of Education reported in 2010 that less than 50% of all American college students who enter as freshmen graduate within the next six years and at some colleges this rate is <10percent!
Yet almost 90% who drop out without a degree do so with more than $10,000 in student loan debt.
Then in 2011 Secretary Duncan announced a statistic that restores hope; "Students...
Each year thousands of high school graduates enter college and five years later only 50% of those who go to a 4 year school will graduate.
Students who start in community college fare much worse; with less than 27% either graduating with an Associates degree or transferring to a 4 year college.
Since a bachelors degree is associated with not only $1M more income than any other post...
Colorado High School Seniors.....Prepare for College.....Then Go Back to the 3R's
This week the US Department of Education released more troubling news about Colorado Schools. In 2010 more students manged to graduate on time from high school but fewer that ever were actually ready for college.
We need to define successful completion of high school by the only criteria that really...
