It's a snow day, and two brothers attending schools with different schedules each got a late start to the day. But who had the shorter school day? That's what your class will find out as they apply their knowledge of fractions to this...

Let's use math to solve an argument. Jon and Charlie are debating about who can run farther, but who is right? That's what your class will figure out as they apply their understanding of fractions to this real-life situation. A simple,...

Trying to get your class to think of decimals as fractions and vice versa can lead to interesting discussions. After all, we can usually understand quickly that 1/4 is .25 but why is 1/7 not so easy to convert? This activity looks...

Rose's commute to school is a fractional distance. After she runs part of the way, your class needs to determine what fractional distance she ran. This problem explores fraction operations through modeling and computation. The...

What better way to learn about fractions than with a couple pizzas? Help Jessica figure out how much of the pizza she has eaten, while teaching your class that fractions refer to a specific whole amount. This problem will be challenging...

Mixed numbers can be added conceptually, algorithmically, and physically. Have the class visualize mixed numbers by adding fraction bars together. They then discover the algorithmic process that simplifies adding mixed numbers. Finally,...

There is more than one way to answer a question; especially when you have fractions in measurement. Here are three questions with real-world situations in which 5th graders are asked to provide answers in three ways: a larger unit of...

Five out of four people have trouble with fractions! After comparing simplifying fractions to simplifying rational expressions, pupils use the same principles to multiply and divide rational expressions. 

Students solve problems with fractions without using a calculator. In this algebra lesson, students practice reducing, converting, adding, subtracting and multiplying fractions. They apply the use of fractions to the real world.

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

This two-day lesson plan will help the class simplifying rational expressions. It also has an emphasis on understanding when a rational expression is undefined. The lesson plan contains powerpoint presentations, worksheets, and answer key.

What do fractions and rational expressions have in common? Everything! Learners use common denominators to solve rational equations. Problems advance from simple to more complex, allowing pupils to fully understand the material before...

Challenge your classes while developing their problem-solving skills. A square is divided neatly into four equal triangles by its diagonals until one diagonal is moved from a vertex to the midpoint of one side. Now, scholars must devise...

The connection between fractions and division is not always intuitive for 5th graders. Pie, on the other hand, is something 5th graders can connect with. Multiple pies divided among multiple people provide the platform for your...

The single question in this activity has multiple ways to be solved. Two boys ran a mile. Their times were similar, except one time was a fraction of the other. Who ran faster? In demonstrating the answer to this problem, upper graders...

Learners rewrite and solve problems using mixed numbers. In this algebra lesson plan, students solve fractions using mixed numbers by addition and subtraction. They relate the use of mixed numbers to real life.

Students solve algebraic proportions. In this algebra lesson, students convert between fractions, percents and decimals. They solve problems using the distributive property.

Students examine and compare traits of humans and crocodiles.  For this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

Students solve equations with variables on both sides. In this algebra instructional activity, students solve equations using addition, subtraction, multiplication and division. They graph their solution on a coordinate plane.

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