Roll to Win Investigation – Graphing Classroom Activity   Graphing is an excellent way to display data visually. Students will come in contact with a variety of data and ways to display this data over time. It is important that students understand that there are three main types of graphs used to display information. The three types of graphs are line graphs, pie charts, and bar graphs.     The type of graph you decide to use depends mostly on the type of data you need to display.  Bar graphs are used to compare things between different groups of data or to look at changes ..read more

Area is All Around Us!  Simple Geometry Classroom Activities   One challenge that students often face is realizing that math DOES actually relate to the real world and that they will actually use the information they are learning at some point in their life. Area happens to be one of those topics that students struggle to understand the reasoning behind.  Before introducing the topic of area, you may want to ask your students some engaging questions such as: “If you wanted to put new tile down on the floor, how would you know how much to buy?” or “If you wanted to put wallpaper ..read more

Multiplication is an operation that requires you to add another number to itself a certain number of times as indicated in the multiplication equation. When students first start learning the concept of multiplication, it is more simple as time goes on for kids to learn. Memorizing multiplication facts works for some students but not for all! Some students need to learn by using different models and representations. When students have a conceptual understanding of multiplication and realize that it is connected to the real world, they tend to perform better on assessments. If a child is on ..read more

Polygons can be defined as two-dimensional, closed figures that are described by the number of sides, length of sides, and the kinds of angles. Many polygons have a respective name depending on their description. Some common polygons you will work with include: triangles, squares, rectangles, trapezoids, quadrilaterals, rhombus, pentagons, hexagons, parallelogram, and octagons. When learning the names of polygons, students can easily be confused by terms that are used interchangeably at times. For example, a quadrilateral is considered to be a four-sided figure. So one might easily confuse thi ..read more

Ever launched a Rocket and wanted to determine how High it goes? Polynomials can come in handy when trying to model the flight path of a Rocket.  Did You Know that  when shooting a rocket straight up in the air, the rocket’s path can be modeled using the polynomial equation: y = -16t2 + vt + ho? Yes, it is True. Using this Equation you can easily Determine when the Rocket will hit the ground and even how far the Rocket will shoot into the sky. The Height the Rocket will reach is dependent on the initial velocity of the rocket and the initial height.  (Rocket Photo:  http ..read more

Harmony occurs in music when two pitches vibrate at frequencies in small integer ratios.  Long ago, Greek people realized the concept of harmony occurred when sounds and frequencies are in rational proportion. i.e., One Octave is equal to when the frequency is doubled, and a tripling of frequency brings the key One Octave higher, and is called a perfect fifth. Though not knowing this in relation to “frequency”, ancient Greeks knew this in relation to lengths of vibrating strings; http://www.math.uwaterloo.ca/~mrubinst/tuning/12.html  (Why 12 Notes to The Octave?)   1/1  un ..read more
