Estimate Sums and Differences

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...

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

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. 

Seven word problems make up this mixed practice learning exercise. Learners perform operations of addition and subtraction to solve problems using numbers up to 2,800. 

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...

Use ratios to solve problems that are not proportions. The instructional activity has pupils solve multi-step ratio problems that involve fractional increases and decreases. The problems involve mark-ups, discounts, commissions, and...

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...

Upper graders solve math problems involving multiplication using specific strategies. They will use base-ten blocks, hundreds charts, and number lines to solve multiplication problems. Then they will practice several of the strategies...

Learn to maneuver through word problems by identifying the specific information needed to solve it. Is there unnecessary information? Is there missing information? 

Addition and subtraction are essential skills for all young mathematicians. Explain the step-by-step process with respect to place value using these real-world examples. Focus is on numbers in the tens, hundreds, and thousands, making...
