Fifth graders practice using the English measuring system by creating fractions.  For this parts of a whole lesson, 5th graders combine math key bars to simulate small parts of a bigger item.  Students combine the pieces to...

Students investigate the results of different propulsion methods. In this propulsion lesson, students measure the distance a test toy car goes using different types of propulsion. They record the distances in data tables before...

Students develop number sense up to a million.  In this developing number sense up to a million instructional activity, students count their breaths in given time span.  Students use blocks representing 10's and 100's to create...

Learners read the book Sam I Am and complete math calculations on the prices of ingredients that Sam did not want to eat. In this math calculations lesson plan, students list the items Sam would not eat into a computer program and...

Second graders find missing addends by solving math word problems. In this missing addend lesson, 2nd graders work in a whole group setting to find the missing addends in word problems before using the strategies to work independently....

Students find math concepts in every day items. In this math concept lesson, students take ten photographs of things they find interesting. They analyze the photographs to find hidden math concepts such as counting, lines, angles,...

Students use the disciplines of math and science to examine ecosystems. In groups, they calculate the amount of supplies they would need to live in the classroom for one day, a week and a year. Using this information, they apply it to...

Students explore math in their everyday lives. In this math lesson, students discuss how they use math in their everyday lives. Students work in groups to brainstorm how they use math everyday.

Students write simple addition number sentences. In this addition lesson, students write simple addition number sentences using tangible objects as their guide. Using a paint or drawing program on the computer, students create a visual...

Students study the concept of fraction using mathematical reasoning. In this problem solving fraction activity, students use various methods to explain their reasoning in solving fractions. Students use a number of different prompts to...

Students listen to the story, "Harriet Goes to the Circus," to launch into a lesson on positional words, such as over, under, and behind. After clipping out and coloring pictures of circus animals, students place them into a parade line...

Students use chips to represent units to show examples and non examples of fractions. In this fraction lesson plan, students show what chips can be used for different fraction scenarios.

Students practice counting and matching quantities using paper fish.  In this early mathematics lesson, students create a fake fishing pole and attempt to identify numbered paper fish they acquire from a bucket.  Students read...

Students investigate the correlation between education and salary. For this business lesson, students analyze the salary rate for different jobs to determine if there is a correlation between the two. They graph their findings and report...

While this lesson provides a motivating and interesting way to review the concept of the order of operations, it involves the use of software called How the West Was One + Three x Four. There are also other resources that are referenced,...

I can multiply, so why can't I add these radicals? Mathematicians use the distributive property to explain addition of radical expressions. As they learn how to add radicals, they then apply that concept to find the perimeter of...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

So what exactly is a random sample? The 15th part in a series of 25 introduces the class to the idea of selecting samples. The teacher leads a discussion about the idea of convenient samples and random samples. Pupils use a random...

How many people can sit around a table? The 22nd part in a series of 36 continues the work on writing and evaluating expressions to include expressions with two operations. Pupils use models to determine an expression for the number of...

Do you view proofs as an essential geometric skill? The resource builds on an understanding of dilations by proving the Dilation Theorem of Segments. Pupils learn to question and verify rather than make assumptions. 

Don't go off on a tangent while writing equations of tangent lines! Scholars determine the equations for tangent lines to circles. They attempt both concrete and abstract examples, such as a tangent line to the unit circle through...

Triangles, triangles, and more triangles! In this second installment of a 36-part series, your young mathematicians explore two increasingly challenging constructions, requiring them to develop a way to construct three triangles that...

Use expected values to analyze games of chance. The 15th installment of a 21-part module has young mathematicians looking at different games involving tickets and deciding which would be the best to play. They calculate expected payoffs...

Develop a formula based upon numerical computations. The 31st part of a 33-part unit has the class determine the formula to convert a temperature in Celsius to a temperature in Fahrenheit. They do this by making comparisons between the...
