This will be my 12th year teaching high school math.  It is my 4th year here in Allegan and I taught the previous 8 years in South Haven.  I attended Central Michigan University for my undergraduate degree and Grand Valley State University to complete my Masters degree in Educational Technology.  I enjoy working with and building relationships with my students as I try to instill in them a love of learning and an appreciation of mathematics.  I enjoy running, reading, gardening, and spending time with my family.

Classes and Essential Standards

I ensure high levels of learning for all students using these essential standards as my guide:

Algebra (Grade 9)

  • Students can solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
  • Students can solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
  • Students can interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship for a function that models a relationship between two quantities.
  • Students can create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear functions.
  • Students can solve systems of linear equations exactly and approximately, focusing on pairs of linear equations in two variables
  • Students can construct exponential functions given a graph, a description of a relationship, or two input-output pairs, including reading those from a table.
  • Students can use the properties of exponents to transform expression and exponential functions.
  • Students can understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
  • Students can factor quadratic expressions to reveal the zeros of the function it defines.
  • Students can graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.
  • Students can solve quadratic equations in one variable (graph, factor, quadratic formula).
  • Students can interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).

Geometry (Grade 9/10)

  • Students can prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent.
  • Students can use coordinate geometry to find midpoints and distance in the coordinate plane.
  • Students can use examples and counterexamples to make logical arguments.
  • Students can use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; given two figures, use the definition of congruence in terms of rigid motions to decide if they are congruent.
  • Students can specify a sequence of transformations that will carry a given figure onto another.
  • Students can prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180°; base angles of isosceles triangles are congruent.
  • Students can explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions.
  • Students can prove theorems about parallelograms. Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.
  • Students can understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.
  • Students can use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
  • Students can derive the equation of a circle of given center and radius.
  • Students can find arc lengths and areas of sectors of circles.
  • Students can use volume formulas for cylinders, pyramids, cones and spheres to solve problems.
