Jessica's Math Material

Step-by-step guide to writing numbers in scientific notation, and how to convert them from scientific notation back to standard form. Includes practice examples. Jessica

This PowerPoint presentation covers the following topics: - Rotation of the Earth and how it creates day and night - Revolution of the Earth and details about how its tilted axis contributes to creating the seasons - Solstices and equinoxes - Why it is hot at the equator and cold at the poles. Lots of pictures and diagrams to demonstrate the concepts!

This presentation discusses - homogeneous and heterogeneous mixtures, provides examples - explains how a particle dissolves. - separation of mixtures: filtration, sedimentation, decantation, and distillation. NEW ADDITION! Basics of solubility, solubility curves. Jessica Rickhaus

This is a 10-page document about solving equations. Each topic begins with steps of how to solve that type of equation in a solved example, followed by practice problems. The topics covered are: - parts of an equation (variable, coefficient, constant) - evaluating expressions - solving 1-step equations - solving 2-step equations - solving and checking your answer - solving equations where you must combine terms first - equations with variables on both sides. Also available in Word format, just

This is a 17-slide presentation that is meant to introduce students to the atom, its components, elements, and how they are arranged in the periodic table. Lots of pictures and animations! Also, on slide #9, the word Element is a link to a website of a song about all of the elements, students love it! Enjoy!

An colourful and animated introduction to logarithms, including converting between log and exponential forms, solving basic exponential equations, and change of base formula, log properties, worked out examples of expanding or condensing log expressions.

This presentation introduces the 2 types of waves: transverse and longitudinal, using the classic slinky examples. It then goes on to define amplitude, frequency and wavelength for each type of wave, and then the speed of a wave formula.

This is a basic guide to understanding what an exponential function is, and how to calculate the rule from a table of values and from word problems. UPDATED to include more details!!

ALSO AVAILABLE AS A WORD DOCUMENT. 9-PAGE DOCUMENT of step-by-step notes and practice problems on the following topics: Definition of exponents and their parts (base, exponent, power) Special exponents (zero, one, negative, fraction) Multiplying and dividing powers with same base Multiplying and dividing polynomials (FOIL and distribution) Adding and subtracting polynomials (LIKE terms)

This 19-slide presentation talks about the 3 states of matter, describing their particle movement and energy level. Then goes on to distinguish between characteristic (boiling point and melting point) and non-characteristic properties of matter (mass, volume and temperature). Some animations and cute examples!

ALSO AVAILABLE IN PDF FORMAT TO KEEP PAGE LAYOUT! 9-PAGE DOCUMENT of step-by-step notes and practice problems on the following topics: Definition of exponents and their parts (base, exponent, power) Special exponents (zero, one, negative, fraction) Multiplying and dividing powers with same base Multiplying and dividing polynomials (FOIL and distribution) Adding and subtracting polynomials.

Notes on the Greatest Integer Function: - definition of greatest integer - basic graph - transformed rule and graph - description of the role of parameters a, b, h, k - steps on how to graph - steps on how to find the rule from a graph - finding domain, range, sign, variation, zeros, initial value Lots of animations!

Notes with animations about the rational function: - basic and transformed rules - detailed role of each parameter - explanation of the asymptotes - how to graph - solving rational equations - finding the rule from a graph - converting from standard rule to general rule - domain, range, sign, variation

This is a 22-slide presentation discussing these topics: - puberty in males and females, glands and hormones involved, primary and secondary sex characteristics - female anatomy - oogenesis, the complete process - phases of the menstrual cycle - how to calculate ovulation date Lots of diagrams and animations, and some homour too!! - when a woman is fertile during her cycle - menopause - external anatomy

This is a formula sheet on ratios of perimeters, areas and volumes of similar solids. My students had a hard time understanding the different ways to calculate the ratios, so I made a review sheet that puts it all together for them. It really helped! Jessica Rickhaus

This is a 26-slide PowerPoint presentation with notes and solved examples (with step-by-step animations) that covers the following topics: - definition of a rational expression - finding the restrictions - simplifying - adding/subtracting with common and uncommon denominators - multiplying/dividing - solving a word problem This should be about 2 weeks worth of notes, when added to extra practice. Also, the slides are much nicer than they appear in the preview!!

Guide to understanding rational functions and how to find the rule from a table of values and word problem, and how to graph it and properties of its graph.

Notes about the transformed exponential function, including: - explanations of each parameter - how each parameter affects the graph of the function - interactive questions to test students' understanding - how to identify the properties of the function - how to solve an exponential function (using change of base) - how to find the rule from a graph - finding the rule from a word problem

This 15-slide presentation solves 4 multiple choice problems about systems of linear relations, all to be solved by looking at the graph of the system given in the problem. The presentation gives detailed steps and reasons as to which choices are/not correct by the use of animations. It also starts off by showing the meaning of a and b (in y = ax + b) on a graph, and how changing those parameters affects the graph.

1-page (legal size) quiz about special exponents (1, 0, negative, fraction) and about multiplying/dividing powers with the same base. Also, an "explain your answer IN WORDS" question at the end. Jessica
