Lambda Algebra I ...
Lambda is the most important and most difficult class in ThinkForFun. Students that complete Lambda with a final score of 90 or above, will be able to score more than 600 in the SAT Math section.The SAT Math section will become very trivial after students complete this level successfully.
Lambda covers all the concepts in Algebra I in a lot of detail and depth; students will be solving all sorts of problems involving line equations, parallel/perpendicular lines, will be able to find distances between point and line, between points, mid points etc. They will also master absolute value eqautions, absolute value inequatilites, 1/2-variable inequalities. ratios and proportions, average, arithmetic sequences and all associated word problems will become second nature to kids in Lambda. They will learn about scientific notation, they will work on complex expressions with exponents, they will learn to solve exponential equations, they will learn about the various types of numbers, rational vs irrational, and will learn to rationalize expressions. They will be able to find the prime factorization of any number, and consequently use it to find root of numbers.
Lambda students will work with polynomials. They will learn to add/subtract/multiply and divide polynomials. They will learn about quadratic equations and their factoring. Most importantly they will learn to solve word problems that are modeled through quadratic equations. Students will review some basic Geometry concepts that were introduced in the previous level Kappa; triangle inequality theorem, complement/supplement angles, volume, surface area, diagonals of polygons, sum of the interior angles of a polygon, etc.
Students will be solving over 500 problems that could cover problems
from Continental Math, Math League, Math Olympiads, AMC8, AMC10 and MATHCOUNTS.
