CMP 7th Grade Resources

 

 

Variables & Patterns
 
Maze Game -  Students practice using ordered pairs by directing a robot through a mine field laid out on the plane.
Number Cruncher - "Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule on without at least having two data points."
 
Whole Number Cruncher - "Similar to "Number Cruncher" but only generates multiplication and addition functions to avoid outputting any negative numbers."
 

Stretching & Shrinking
Side Length and Area of Similar Figures - Tool to illustrate how perimeters, areas, and side lengths of similar rectangles are related.
Logo Playground - Use Logo commands to draw similar figures.
 

Comparing & Scaling
 
Proportions: Mixing Orange Juice - Students will use the visual applet to compare ratios.  Download and print the worksheet to go along with the applet.
 
Paper Pool Game - "The paper pool game provides an opportunity for students to develop their understanding of ratio, proportion, greatest common divisor, and least common multiple."
 
Balance Applet - Use the balance to determine the weight of each shape.
 

Accentuate the Negative
Number Line Bounce - Use the number line to practice integer addition and subtraction.
Color Chips: Addition - "Use the color chips to illustrate addition of integers."
Color Chips: Subtraction - "Use color chips to illustrate subtraction of integers."
 
Operations on a Number Line - Use a number line to add and subtract integers.
Pan Balance: Numbers - This tool can be used to investigate operations with integers.

Moving Straight Ahead
 
Number Worlds - Students investigate linear properties of multiples that have been shifted on a 12 by 12 grid.
 
Function Machine - "Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs."
Function Flyer - "A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers."
 
Grapher - "A tool for graphing and exploring functions."
 
Graphit - "Students can graph functions and sets of ordered pairs on the same coordinate plane -- similar to a graphing calculator."
 
Linear Function Machine - "Students investigate linear functions by trying to guess the slope and intercept from inputs and outputs."
 
Find the Equation of the Line - Use the applet to find the correct equation of the given line.
 
Geoboard: Coordinate - Rectangular geoboard with x and y coordinates.
 
Real Life Data - The following three applets use real-life situations to show how changing the values affect a table and graph. Use them separately or download instructions for using them together. Real-life Data, Example 1,   Real-life Data, Example 2,  Real-life Data, Example 3
 
Algebra Balance Scales - "Solve simple linear equations using a balance beam representation."
 
Distance, Speed, and Time Applet - Software simulation of two runners along a track.
 
 

Filling & Wrapping
 
Cube Nets - "Examine various two-dimensional figures to determine which ones can be folded into a cube."
 
Cubes - The volume of a box can be determined by using this applet to manipulate and enumerate unit cubes, rows of unit cubes, or layers of unit cubes."
 
Side Length, Surface Area, and Volume of Similar Solids - Tool to investigate how changing the lengths of the sides of a rectangular prism affects the volume and surface area of the prism.
Surface Area and Volume - "Students manipulate dimensions of polyhedra, and watch how the surface area and volume change."
 
 Platonic Solids - "Identify characteristics of the Platonic Solids."
 
Space Blocks - "Create and discover patterns using three dimensional blocks."
 
Geoboard: Isometric - "Use the geoboard to illustrate 3-D shapes.
 
How High - Compare the volumes.
 

What Do You Expect?
 
Pick-a Block - This tool simulates picking colored blocks. 
 

2 Colors Applet - Students choose between three boxes and choose one marble from the box to look at conditional probabilities.
 

Marbles - Students learn about sampling with and without replacement by modeling drawing marbles from a bag.
 

Dice Table - Students experiment with the outcome distribution for a roll of two dice by playing a dice throwing game.
 
Fire - Students work with probabilities as a fire burns tress in a forest.
 
Directable Fire - Students run a simulation of how a fire will spread through a stand of trees.
 
A Better Fire - Students run a simulation of how fire will spread through a stand of trees.
 
Box Model - "Randomly selects and displays draws from a box."
 
Understanding Experimental Probability - "Experiment with experimental probability using a fixed size section spinner, a variable section spinner, 2 regular 6-sided number cubes or design your own number cubes."
 

Data Distributions
 
 
Plop It - "Students click to build dot plots of data and view how the mean, median, and mode change as numbers are added to the plot."
