Learn how to increase the probability of success. The 19th installment of a 21-part module teaches future mathematicians how to use probability to analyze decisions. They determine strategies to maximize the chances of a desired outcome.

Students play dominoes with regular dominoes rules with some modification. Every student keep score. Every count be used--not just the 5's as in dominoes. They count outside points using white dots as positive and red dots as negatives.

Students explore sampling with and without replacement. They explore the effects on the probability of drawing a desired object. Students examine probability and the difference between sampling with and without replacement.

Students participate in various activities that increase their understanding of and ability to solve problems with fractions.

Fourth graders use square tiles to help them explain the concept of square numbers.

Fourth graders learn the numerical value of each underlined letter of the standard Rod Code and develop systematic usage for building new units.

Students attempt to put puzzle pieces together with no prior knowledge. This activity shows students at the beginning of the year that history is like a puzzle, there are often missing pieces, and many ways the pieces can turn to look...

Use this chart to explore counting and number patterns up to 100. Choose from thirty different colors for your paintbrush as well as five different versions of the hundreds chart, or start with a blank chart. There is also an auto color...

Learn multiplication by using this versatile interactive times table grid. Users can find the product of two numbers from 1 through 12, color in rows and columns, and look for patterns throughout the chart.

In this activity, the student can visually identify number patterns in Pascal's triangle by coloring multiples of a given number.
