One approach for finding area is to surround the shape with a rectangle, determine the areas of the rectangle and subtract the pieces of the rectangle that are outside the original shape. Use this geoboard to create shapes and determine their areas.
The process of converting fractions to decimals can help clarify the relationship between the two. Investigate the repeating parts that emerge when you expand sevenths and 13ths fractions into decimals.
The connected machine is a single function that takes an input, runs it through the network inside and produces an output. You control a network of function machines along with the input and the operation performed by each machine to solve problems.
A cross section is the face you get when you make one slice through an object. See how many shapes you can make when you cut different cross sections of a cube.
To find the area of a shape, surround the shape with a rectangle, determine the areas of the rectangle and subtract the pieces of the rectangle that are outside the original shape. Use this geoboard to create shapes and determine their areas.
The colors listed in the boxes represent different parts of speech: noun, verb, adjective, adverb, etc. Figure out which colors represent which part of speech and then use the colors to create proper sentences.
To find a hidden treasure use taxicab geometry, a special kind of geometry that counts in city blocks. Pick an intersection, ask the computer how far it is to the treasure and get the distance using taxicab geometry.
There are many sources of variation in data, including random error and bias. Observe the difference between error and bias in this line matching exercise.
Practice locating the median for odd and even data sets. Consider the information you can glean from a set of data even if you only have Min, Med and Max.
Build as many different looking towers as is possible, each exactly four cubes high using two colors of Unifix® Cubes. Convince yourself and others that you have found all possible towers four cubes high and that you have no duplicates.
You can find the areas of different polygons by dissecting the polygons and rearranging the pieces into a recognizable simpler shape. Cut a circle into wedges and fit them together to form a crude parallelogram.
Which hexomino net wastes the least amount of paper and yields the most boxes per sheet? Comment on how concepts such as area, spatial visualization and relationships among geometric shapes are all involved in solving this problem.
A computer can perform random sampling and estimation faster than you can. Use the computer to help you estimate a penguin population from computer-selected random samples.
The concept of the arithmetic mean and deviation from the mean can be graphically representated as a line plot. You will create a line plot to represent specified allocations of coins.
