Save download time—install software now in preparation for future lessons. The R statistical software is a free program used by the Federal Reserve Bank and many companies. Bring the power of the software to your classroom to use in the...

Can multiple computers sort a list faster than one? Using a network drawn with chalk outside, groups move through the decision network to sort numbers. A series of extension questions come with the lesson and can be used in the same...

How do we determine how much information to include and what can be left out? By playing a game of 20 questions, the class generates the best strategies for finding a number. They then move on to guessing the next letter in a short...

How does a computer perform a search in order to find data? The lesson begins with a demonstration on finding one number out of 15. Pairs then play three games of Battleship by using different search techniques. The lesson...

Third graders explore the place values of four digit numbers by writing four digit numbers and examining the effects of rearranging the numbers' digits. They practice making their four digit number with base-ten blocks then rearrange the...

Check out the handout from a presentation that contains a collection of high school algebra projects connecting a variety of mathematics to the real world. Activities range from simple probabilities to calculus. The activities...

Students explore multiplication concepts.  In this multiplication lesson, students define "array" and draw several arrays to represent multiplication number sentences.  Students construct arrays on the computer using MathKeys...

Students explore geometry by utilizing computer software. In this shape identification lesson, students define several geometric shapes by the characteristics that classify them. Students draw and cut out geometric shapes using their...

Explore the mathematics of infection outbreaks with activities that ask learners to use coordinate grids to locate infected patients. They calculate amounts of ingredients for antidotes and determine which groups of people should be...

Investigate the Remainder Theorem in this algebra lesson. Explore the relationship between the remainders of polynomial division and the function. Each of the four problems gets progressively more complicated. This might be a great...

Investigate sound waves with acoustic mirrors. Using audio software, groups make recordings of musical instruments, both with and without acoustic mirrors. They compare the recordings to see the effect of acoustic mirrors on sound...

Students explore using mathematics to solve problems in base two. After a teacher demonstration of using base two to write numbers. students model similar problems to explore the concept of number systems in different bases. To increase...

Hard boiled or raw? Which egg will you get? A hands-on activity has scholars explore the impact of conditional probability. Based on a skit from the Tonight Show, pupils model the selection of the two types of eggs using beads. They...

Learners engage in six activities to lead them through the process of conducting a thorough analysis of data. Pupils work with calculating standard deviations and z-scores, finding the area under a normal curve, and sampling...

Students utilize computer programs to operate a simple robot.  In this technology lesson, students create robots using Lego pieces and simple motors to move them.  Students measure the speed of the robots by running Robolab...

Using geoboards, computer programs, and hands-on manipulative materials, elementary schoolers engage in a study of two and three-dimensional geometric shapes. This lesson is chock full of good teaching ideas on the subject, and the...

Young mathematicians identify shapes and their correct names. They work with partners using various manipulatives and computer software to reinforce the concept. I really like these lesson plans. They are well-designed, the procedures...

Students practice identifying quantities of items and materials using numbers.  In this counting lesson, students read The Gummi Bear Counting Book by Lindley Boegehold, and utilize a bag of gummy bears as a counting tool....

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Small groups work through two guided activities to derive the distance and midpoint formulas for the coordinate plane. The activities begin with concrete examples and move to abstract.

Students practice graphing activities. In this graphing instructional activity, students discuss ways to collect data and complete survey activities. Students visit a table and graphs website and then a create a graph website to practice...

Research data analysis by creating charts in class. Define the differences between an "average" and "range" while examining measurement data based on student height. Utilize computer software to create a height graph which is shared with...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...
