in Nov & Dec, the yøløsix KIDS will hope to:
— become comfy with the relationship between writing numbers as either fractions, decimals or percents. this will eat up a fair amount of our time in November and early December – this is CRUCIAL mathematical material to have reasonable command over before moving forward!
—- a much more in depth study of fraction operations – the BIG FOUR – add/sub/mult/div – it’s a bit of a personal crusade of mine to help my students master the methods and, much more importantly, DIFFERENTIATE between where & when to apply the appropriate rules in the appropriate situations.
that should keep us pretty busy through the holidays!
in the upcoming month PLUS until we reach Winter Break, the Mathletes of The Seventh Grade hope to/plan to:
— continue an in depth investigation of solving one variable equations, with a focus on solving word problems (translation of the problem into an equation & learning to avoid unnecessary traps of said word problems – mainly to NOT get intimidated by them!) and also dealing with MORE COMPLEX one variable equations (with variables on both sides and grouping symbols…)
— learn about graphing & solving inequalities; learning to flip the sign when dividing or multiplying by a negative
— we might get to a review of fractions, decimals & percents before the break (if not, that will be what we’ll hit in January!)
and we always, always are digging deeper and talking about not just the HOW TO but also the WHY or WHY NOT of all the algorithms and rules we are asked to obey!
as we enter the SECOND TRIMESTER of school (that sounds strange…), these are the burning mathematical issues we will deal with:
— continued work on test prep for approaching HSPT & NT Placement Exam
— in depth study of Linear Equations – functions, slope, point slope & slope intercept form, finding intercepts, word problems with linear equations, solving systems of equations
it’s a choppy time of year in terms of the calendar & holidays, but this is my ninth year in this teaching game, so I am used to making progress with my classes in the face of every type of adversity.
upward and onward, as it has been said!
that is all….for now.
The New Trier Placement Test is coming soon (Sat, December 7th).
I am attaching the letter you should have received with pertinent information about the exam.
I will conduct review sessions on the week before the exam with my 8th graders.
well, we REALLY hunkered down in the world of integers. we’ve become experts at adding, subtracting, multiplying & dividing integers but, more challengingly, we’ve become rather proficient at applying integer operations in the context of OBEYING THE ORDER OF OPERATIONS; something probably a bit above our 6th grade pay grade, but nobody got hurt and in fact, much confidence was gained.
so, closing out the month – we’ll shift into major operations with fractions which will begin with a study of divisibility, prime factorization, GCF, and then, likely well into November, we’ll work on multiplying, dividing, adding & subtracting fractions (including negatives and mixed numbers).
for the month of October, we’ve set our sights on rational numbers – more specifically on fractions – we already talked about factors, greatest common factor, simplifying algebraic fractions – currently, we’re performing all four of the MAIN OPERATIONS (add, sub, mult, divvy) on all kinds of fractions. in mid October, we’ll take a big test on fraction ops; from there, we’ll move to probability to close out the month.
in November, we’ll work a unit on statistics – we’ll spend a lot of Q.T. (quality time) with stats and, more importantly, studying how statistics are used in various fields and how we can become healthy skeptics when presented with some statistics in science, social studies or wherever!
this October, we have been working or will work on:
— solving complex one variable equations
— setting up & solving basic one variable word problems
— working with proportions & percents – focus on word problems (simple interest / percent of change)
a continuing GOAL and FOCUS is working with accuracy & speed on short quizzes (almost every morning, we’ll take a 5 to 10 minute quiz on problems from topics current and not so current)
this will get you to the Explore Test site for anyone who wishes to get more information on the exam that will be given on:
