There are so many ways to solve any given math problem. Get your problem-solving basics covered with this handy slide show. Various calculation methods are used to solve multiplication, addition, subtraction, and division problems...

Kids love to cook! What is a better place to learn mixed numbers than with a recipe? It is up to learners to decide how they want to divide this recipe in half. They may choose to model the mixed number and then divide the model by two....

All hail the king! Young mathematicians put their skills to the test as they strive to become the king of math.

You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson begins...

Boost emotional intelligence and division skills with a three-question activity featuring two imaginary towns that record when citizens hurt, forgive, or punish one another. Using division, scholars calculate each problem to decide...

Discover how the distributive property applies to division. As learners change numeric values within an expression, the simulation calculates its value. Challenge questions lead individuals to realize the power of distributing the...

Model expression division using online manipulatives. Learners drag C's representing a term into equal groups. Guiding questions help them see their groups as the division of the term.

Cells divide by one of two processes, either mitosis or meiosis. Scholars sort cards into two sets, one representing each type of cell division. Then, they sequence the cards demonstrating an understanding of the movement of chromosomes.

Find out when rational expressions are closed. Pupils review adding, subtracting, multiplying, and dividing with rational numbers to make the connections to operations with rational expressions. Using specific examples, learners notice...

Chicago is one city, four neighborhoods, and countless nationalities. The lesson explores the ethnic division of Chicago in the early twentieth century. Academics read primary sources, analyze maps, and tour an online exhibit to...

A hands-on experiment applies chromatography to separate both the colors and components of grape-flavored Kool-Aid. Performing two separate activities, learners first use chromatography to divide the colors. The second activity results...

Is time on your side? Pupils come up with an experiment to test whether their classmates can guess how long it takes for 30 seconds to elapse. They divide the class data into two groups, create box-and-whisker plots, and analyze the...

The magic number is six! Using a 6x table, young math stars practice adding, subtracting, multiplying, and dividing two-digit numbers with the number six. This worksheet also touches on making tessellations with hexagons. 

What starts as a basic question of division and remainders quickly turns abstract in this question of related ratios and radii. The class works to surround a central coin with coins of the same and different values, then develops a...

Young mathematicians analyze computation errors by three hypothetical learners. It begins with a scenario that presents an equation that includes addition, multiplication, division, and subtraction. According to the order of operations,...

What would it take to live on the lunar surface? Small groups build model rockets in order to simulate launching a habitat into space and rebuilding it. Divide the class into groups to design and build a model of a lunar habitat. The...

Mo' money, mo' problems! But don't worry, here is an assessment that proves to young mathematicians that they can solve actual money problems. The resource includes 11 money problems involving addition, subtraction, multiplication,...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

In 1980, in the tropical rainforests of Panama, scientists discovered 1,200 species of beetles living in and around just 19 trees, with most of the species new to science—that's biodiversity! In the activity, learners work in teams to...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this lesson builds off of that concept by having pupils use a data table to create their own scale models of the interiors of...

What in the world is the zeroth power? Examine the patterns of exponents as they apply to the zeroth power. Scholars apply the zero property to simple exponential expressions in this fourth lesson in a series of 15. The examples include...

Forget hours, divide the day into radians instead. Class members convert the angles in a pie chart of daily activities into radian measures. They add angle measures for multiple activities then determine a relationship between the radian...

Explore the chemical components of water through an electrolysis reaction. Scholars use a battery to divide various water solutions into different gases. As they collect the gases, they measure the volume and make a comparison to the...
