Subtracting Integers

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...

Show your class all the hard work you have put into their lesson by showing this PowerPoint presentation. They will not only be proud of you, but it will help them solve multiplication and division word problems using the algorithms.

This problem solving PowerPoint presents a detailed, logical sequence of steps to follow in order to solve a story problem. The thinking processes described are given in text and represented by a visual model. After discussing the...

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

If you are looking for an end-of-the-year math assessment, then this instructional activity 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...
