Invite your pupils to represent a club, team or other group with a trophy of their own creation. Learners examine the Taylor Cup by Laurent Amiot and then prepare trophy designs. When the sketches are complete, pupils sculpt the final...

Represent the African diaspora with figurines. Using a discussion on the contributions of people of African descent as inspiration, class members prepare sketches of a figure and put together a small sculpture from those sketches.

Unfortunately the world isn't fair, but exactly how unfair is it? In this cross-curricular lesson, young mathematicians explore the uneven distribution of wealth in the United States, using their knowledge of percents and proportions to...

Conclude an introductory lesson on ratios with a short four-question quiz. Starting with two word problems asking young mathematicians to determine the ratios described in real-world contexts, learners must then fill in the missing...

Help young scientists connect with nature and learn about trees with a fun life science lesson. Heading out into the school yard, children choose a tree to adopt, taking measurements, writing descriptions, and drawing sketches of it in...

Did you know that a standard pencil can produce a line that is 35 miles long? This and other pencil trivia make up the information that is used in solving proportion problems on this five-problem learning exercise.

Why does Nia's water taste saltier than Trey's if she put more into her cup than he did? Math masters set up proportions in order to compare the mixtures. This task effectively has learners apply the concepts of ratio and proportion to a...

Revisit the 2012 Summer Olympics by having seventh graders calculate the unit rate sprinting speed of the 100-meter gold medal winner. 

Real-world multiple-step proportion problems are sometimes hard to find for your math class. Here is one designed specifically to meet that need. Learners use proportional relationships to determine price per share in the acquisition of...

We've got the beat! And your musically-minded mathematicians will tap their toes as they determine which music company would be getting a better deal based on their offers to buy out TunesTown. The topic is extended in an additional task...

More on the fictitious takeover of the Apple Corporation by Microsoft. In this scenario, Microsoft has $28.00 per share to spare, so how many do they need to offer to make an even trade? This is an engaging problem to solve when...

Student statisticians calculate ratios to determine how many shades of green were mixed by Ms. Baca's art class. They graph the number of blue parts against the number of yellow parts for each combination and discover that some produce...

Join Zoe and Sam as they use proportions to budget money for their Green Earth Club. Watch as they set up and solve a series of proportions using cross multiplication and division. A great resource that brings together prior knowledge of...

Equations can be used to express proportions with y=mx once we solve for the constant. The video introduces the constant of proportionality at the beginning and goes into more detail at the end. The example shares the cost of a whole...

Another word problem to figure out. Well, first off you are trying to figure out the percent of something and this means your formula will be a proportional equivalent. Once you have the known terms in the correct places you can figure...

A model car, a life size car, now compare their sizes. Hmmm. Ok, set up a proportion and then figure out a ratio, and now you can express the relationship in terms of scale. Watch this video and the teacher will demonstrate just how to...

The teacher demonstrates how to set up a word problem into a proportion. There are many ways to solve this equivalent ratios problem and the instructor chooses to find a multiplier to find the missing value.

Find the missing value in this proportional equation. Look at the relationship of the two numerators and the two denominators to solve this proportional ratio.

In this word problem, the skill to remember is to match up the similar measurements. This means the inches match up with the inches and the feet match up with the feet measurements. This problem is a ratio and is written as fractions....

Here's a real-world problem to figure out. Are the gardens all similarly proportional in the number of vegetable plants to the number of flowers? The instructor sets up a table of the values of each garden. She then writes each set as a...

Are these two given ratios proportional? One quick and easy way to answer this question is to cross multiply the two values. If the products are equal then they are proportional ratios. If they are not equal then they are not...

So x amount of people were surveyed and 68 of them said algebra was their favorite subject. Set up a percent proportion to identify the number of people surveyed. That's often the hardest part, setting up the equation. So observe the...

Here's a quick look at percentages as proportions. Percentages really are looking at numbers as a part of a whole, so it makes sense to look at it as a proportion. And how do you write proportion? You write proportions like a fraction,...
