Convert fractions that cannot be written with a denominator that is a power of 10. Pupils use the definition of a fraction and long division to convert fractions to decimals, then discover that some divisions terminate and others...

Provide a meaningful context for learning about the division of fractions with this upper-elementary math lesson. Presented with a simple, real-world problem, young mathematicians work in small groups to develop visual models...

What do I do with what is left over? The formative assessment instructional activity lets individuals show what they understand about remainders in multi-digit division problems. Teams work together to match drawings with division...

This turn-key unit on ratios and unit rates walks through a 30-lesson unit on teaching proportional reasoning, with each lesson broken into detailed teaching notes and time allotments for all parts. An unbelievable resource when taken...

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...

This resource will blow your mind! Young mathematicians estimate the rate of volcanic lava flow by watching a video. They apply the rate formula to determine how long it would take the lava to reach a city. Let's hope everyone gets out...

Making money is important to teenagers. It is up to your apprentices to determine how much two wage earners make with their after school jobs. Participants work with a table, an equation, and a graph and compare the two workers to see...

Remodeling projects require more than just a good design — they involve complex fractions, too. To determine whether a tiling project will fit within a given budget pupils calculate the square footage to determine the number of...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

How many hands tall are you? Challenge kids to measure themselves the way the 19th century Oklahoma horse traders measured their prize horses (can they guess how many hands tall a horse had to be?). There's some background information...

Your pupils may believe that you and their parents are the oldest things in the universe, but surprise! There are elements of the universe that are even older. Elementary scientists create a class timeline to demonstrate the...

Sorting fractions, integers, decimals and square roots into sequential order is an active process when you use a gym as your setting. After your class is divided into two groups and provided with number cards, they compete to see who can...

Take the opportunity to offer your young adults some important financial wisdom on the way taxes and inflation will affect their lives in the future. Through discussion and review of different real-world scenarios provided...
