The process of elimination really works! Use elimination when substitution isn't doing the job. The 29th segment in a series of 33 introduces the elimination method to solving linear systems. Pupils work several exercises to grasp the...

The 19th installment in a 25-part series builds upon the sampling from the previous unit and takes a larger sample. Pupils compare the dot plots of sample means using two different sample sizes to find which one has the better variability.

Young scholars identify and label acute, obtuse, and right angles within a picture. Using Kid Pix software and digital photos, they manipulate, identify, and label the angles and describe the angles to a classmate.

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...

Using Google SketchUp, learners draw a model of their bedroom. They begin by measuring the dimensions of their bedroom, inputting this information into the software program, and calculating perimeter and area. This is an interesting and...

Design a plan for finding the best health insurance for your money. Learners compare two health plans by writing and graphing piecewise functions representing the plan rules. Using Excel software, they create a technical report...

Complex doesn't have to mean harder! Learners experiment with online software to determine the quadratic equations with complex solutions. They use the quadratic formula to solve equations with both real and complex solutions.

It's not a sprint, it's a marathon! Statistic concepts take time to develop and understand. A guided activity provides an opportunity for individuals to practice their linear regression techniques in spreadsheet software. The activity...

Ever dream of becoming an architect? Here's your chance to give it a try. After reviewing facts about triangles and quadrilaterals, pupils learn about the basics of architecture by talking to an architect or housing expert. They use...

Save the world by designing a new soda can! Learners first measure the dimensions of a typical soda can and calculate its surface area and volume. They then use spreadsheet software to minimize the surface area for the volume, thus...

Lead by example. Pupils use software to investigate given measures of sides and angles to determine whether they create congruent triangles. Using the discovered triangle congruences, learners put together proofs.

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...

First graders play the game Show Me and use math software to practice place value.

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...

In this similar triangles worksheet, students solve 20 short answer problems. Students determine if two given triangles are similar.  Students determine the type of similarity given two triangles. Students are given a sketch of the...

Students develop a budget for a college student using all of the influences that the student would have.  In this budgeting lesson plan, students use real life examples to create a budget spreadsheet.  Students read and study...

In this classifying quadrilaterals worksheet, students classify 18 quadrilaterals in short answer format. Students use quadrilateral properties of classify quadrilaterals given a sketch.

For this angles in quadrilaterals worksheet, high schoolers solve 18 short answer problems. Students find unknown angles in a quadrilateral given a sketch of various quadrilaterals with unknown angle measurements.

Learners create a spreadsheet that they will use to plan a small party or outing. They calculate expenses and stay within a budget amount for their party.

Students solve problems using technology. In this algebra lesson, students apply flow diagrams and computer codes to solve problems. They use the TI to view the graphs.
