Students calculate the slope of parallel and perpendicular lines.In this algebra lesson, students differentiate between parallel and perpendicular lines. They graph their lines using the slope of the equation.

Students find the slopes for perpendicular and parallel lines. In this geometry lesson, students differentiate between parallel and perpendicular lines. They use Cabri software to create lines to compare.

Students explore measuring with a graduated cylinder. In this measurement instructional activity, students observe liquids in a beaker. Students predict the volume of liquid in the beaker and then transfer the liquid to a graduated...

Students practice finding the sums of two-one digit numbers. In this addition lesson plan, students also record facts onto an addition chart.

Students study related addition and subtraction facts. In this math lesson plan, students use related addition and subtraction to solve problems. Students use manipulatives to explore fact families.

Learners explore the additive identity property where they add multiple numbers to get to the number 6. In this number 6 lesson plan, students also work on their addition charts.

Seventh graders simulate the capture-recapture method of population sampling using beans. In this biology lesson, 7th graders calculate the total population of beans in the bowl. They assess whether this method is reliable or not.

Pupils rotate through work stations where they compute problems of theoretical and experimental probability. For this probability lesson plan, students use simulations of a lottery system.

Seventh graders calculate percentages when given a fraction. They convert a percentage to a fraction. All of this be done by each student's ability to read the graphs made available by the spreadsheet information.

Fourth graders determine the value of ? by measuring the circumference and diameter of circular objects such as soup cans, Oreo cookies, etc..

Students gain an better understanding of how to figure out parts of a whole.

Fourth graders measure the height and arm span of various classmates. They use a spreadsheet to design a graph that shows the class measurements from tallest to shortest in metric and standard systems.

In this math worksheet, students examine the answers to a formal assessment focusing on the concepts of ratio, proportion, and percent.

Students observe and discuss cloud cover. They identify percent of cloud cover, calculate cloud cover by fraction and convert to a percent, and compare their models with the current real sky cloud cover.

Students design and build a snowplow using LEGO materials. They compete in an Engineer's Challenge to clear a path through Styrofoam peanuts.

Third graders discuss discounts and walk around classroom labeled with lots of discounted merchandise. They complete a worksheet converting original prices to new bargain prices.

Students use a given spreadsheet to investigate an iterative process by changing the variables. They design their own spreadsheet to investigate the iterative process.

Students begin the lesson plan by noting the many ways in which to use peanuts. In groups, they use the internet to research the work of George Washington Carver. They discover the allergies and nutritional information of the peanut and...

Students toss candy and coins using their non-dominant hand while their partners records the results on a probability charts.

Students collect data and make a frequency table, change ratios into percents, and analyze data to make predictions.

Students design a United States flag using reasoning. They describe their design to make it easy for it to be duplicated. They share their designs with the class.

Students explore the problem of percentages. Students find a given fraction or percentage of a quantity. Students devise and use problem solving strategies on problems explored.

Seventh graders use educational software in order to practice lesson objectives. They define rate and ratio. Students solve distance problems given two variables. They also use a problem solving strategy that can be defended in its usage.

In this mathematical worksheet, students convert fifteen metric units of capacity and multiply and divide whole numbers by 10, 100 and 1000.
