Operations with Integers (A)

Combine total quantities and equivalent ratios in problem solving. The fifth lesson in a series of 29 presents problems that can be solved using equivalent ratios. Pupils use part-to-part ratios and either sums or differences of the...

Changing ratios make for interesting problems. Pupils solve problems that involve ratios between two quantities that change. Groups use tape diagrams to represent and solve classroom exercises and share their solutions. 

Address any kind of math concept or problem with a series of problem-solving strategies. Over 12 days of different activities and increasing skills, learners practice different ways to solve problems, check their answers, and reflect...

Harness the power of algebra to solve problems. Young mathematicians learn to work out multi-step problems by applying algebraic techniques, such as solving equations and proportions. They use tape diagrams to model the problem to finish...

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

There's nothing negative about this mini-unit on integers! Engaging young mathematicians in a series of hands-on activities and collaborative learning opportunities, this resource offers an excellent way to introduce your class...

Time to practice linear equations. The sectioned worksheet starts with simple linear problems and increases to multi-step and rational coefficient problems. 

Rounding has a significant impact on future calculations. Help your learners realize this significance with a thorough video lesson. Using multiple examples, the instructor calculates the upper bound and lower bound of several...

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...

These presentations by Monica Yuskaitis are particularly good. In this one, she shows viewers how to deal with subtracting fractions that have unlike denominator, no small task! This is a tricky process, and this PowerPoint takes young...
