If you are looking for an end-of-the-year math assessment, then this lesson could be for you! Your mathematicians are assessed on their ability to solve difficult, multi-step word problems that take quite a bit of thought and...

Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns.  Scholars could find the answer algebraically or create a table to analyze the...

Add some randomization into simulations. The 11th installment in a series of 25 presents two new methods to use in simulations--colored disks, and random numbers. Pupils use random numbers to run simulations where the probabilities make...

How much sugar is in one bottle? Pupils use double number line diagrams to determine the amount of sugar in a 1L bottle of cola. The teacher leads a discussion on ways that double number lines can be of assistance in solving a...

What does geometry have to do with depression? It's an angle of course! Learners apply the tangent ratio to problem solving questions by finding missing lengths. Problems include angles of elevation and angles of depression. Pupils make...

Students explore problem solving strategies.  In this middle school mathematics lesson, students investigate the guess and test and make a table problem solving strategies.  Students work in pairs to apply the problem solving...

Mixtures, weighted percentages, and varying speeds make problem solving difficult. The resource give learners a strategy for tackling these types of problems effectively. 

Whoops! Travis accidentally put too much butter into the recipe. Your bakers must find out how to alter the recipe to accommodate different changes by using unit rates and ratios . The activity has multiple parts and calculations with...

Great things come in small packages! What better way to illustrate this point than a week-long look at nanotechnology? Earth science scholars explore water quality issues through lab activities, then research new innovations in nanotech...

Ninth graders solve problems using Polya's 4 steps to problem solving.

Don't table the discussion on equivalent ratios — do it now! Scholars create tables of equivalent ratios to represent contextual problems. Pupils go on to use the tables to answer questions within the context. The lesson is ninth in a...

When given too much data to simply memorize, it helps to sort it into manageable groups. The second lesson in the six-part series of Cosmic Chemistry challenges groups of pupils to take a large amount of data and figure out how to best...

Decide which concentration of mixtures is the strongest. Pupils use tables to compare ratios involved in mixtures. They use two methods to make the comparisons — by finding equivalent values within the tables or by comparing the...

Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

Capture the engagement of young mathematicians with this upper-elementary math lesson on measuring time and distance. Using Google Maps, young scholars first measure and compare the distance and time it takes to travel between...

Solving these percent problems is a matter of counting. Pupils find percents by counting the number of events that meet the criteria and the total number of possibilities. Participants create the ratio and convert it to a percent to...

The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

Have class discussions about decision-making and how to solve real life problems with your learners. They will watch videos, talk about truths, fill out outlines, and more.

In this make a table worksheet, students read real world questions and write an equation to match the equation. Next, they solve the equation.   This one-page worksheet contains two problems.

Taxi! Have your travelers figure out how far they can go in a taxi for $10.00. They must account for the mileage rate and tip in their calculation. They can set up a table or make an equation to solve for the exact mileage they can...

Linear equations are the focus of activities that ask learners to first complete a task that involves interpreting algebraic expressions and solving linear equations. They then take part in a card activity matching...

Build tables by understanding their structure. Scholars take a closer look at the structure of ratio tables in the 10th segment in a 29-part series. Individuals realize that the tables can be built using an additive or...

Use the Law of Cosines and the Law of Sines to solve problems using the sums of vectors. Pupils work on several different types of real-world problems that can be modeled using triangles with three known measurements. In the process,...

Learners solve division problems. In this multiplication and division lesson, pupils practice using a multiplication table to find a missing factor in a multiplication sentence. They use the same strategy to find a missing quotient in...
