How do you solve a problem when a symbol or letter is used in place of a missing number? Build algebraic reasoning and problem solving skills with this presentation that explains three methods for finding a missing variable. The guess...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

The process for balancing chemical equations is stepped through slide by slide in this presentation. For some strange reason, the subscripts for certain elements are not dropped down on the first slide only, so you may want to copy the...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

There is no substitute for checking the solution. A short introduction to the substitution method of solving systems of equations is an ideal resource for algebra classes. The slides present steps for the substitution method and...

Eliminate the obvious. A series of slides presents algebra classes with step-by-step procedures for solving systems of equations using the elimination method. It provides an introduction to the elimination method for...

Just when a young mathematician starts to feel comfortable turning word problems into linear equations, shake things up and throw inequalities in the mix. This excellent, instructive presentation takes the steps for solving an...

The example of two travelers meeting somewhere along the road has been a stereotypical joke about algebra as long as algebra has existed. Here in this detailed presentation, this old trope gets a careful and approachable treatment....

Looking to review solving systems of equations algebraically? An educational slideshow presentation explains the methods of elimination and substitution, works through example problems, and provides practice problems. 

A wonderful way to introduce or practice simple algebraic equations, where a variable is used in place of a number. Learners will work to crack the Da Vinci Code (as it is called) and replace letter variables with the "code" numbers to...

Lead your class on an exploration of basic algebra using this resource. As part of a game, learners answer algebra questions involving addition, subtraction, multiplication, and division. 

What assumptions are made in order to solve equations? An instructional slideshow provides an overview and guided examples of how properties of equality can be used to justify each step in solving equations.

Your class can learn all about inverse operations. They will review what inverse operations are, see examples, learn how to use inverse operation to check an answer, write addition and subtraction equations in the inverse, and use the...

Quiz time review! Practice solving fraction and decimal problems.  Use number sense and algebraic thinking to find answers. Review measurement and geometric equations used to solve area.

If you like to start each day with a new math challenge or warm-up, this resource is a must have. It includes 36 slides, each containing a different math challenge that stimulates algebraic reasoning, problem solving, and basic math...

Similar to the popular game Jeopardy, pre-algebra students will play to win. This game focuses on solving and writing simple equations using subtraction, multiplication, or addition. A great way to review for the big test!

Put expressions, equations, and inequalities to work! Young scholars solve problems using various strategies. Meant as a snapshot of the Smarter Balanced Assessment, a set of seven questions includes topics from writing expressions to...

Solving word problems requires reading comprehension and math computation. Through an interactive slideshow presentation, fourth graders observe and follow each step toward solve multiplication and division word problems. 

To solve or not to solve that is the problem. A slide presentation of 17 items show different ways that Smarter Balanced assesses Claim 2, problem solving. The items span from sixth and seventh grade concepts to highlight the...

Making money and saving money turn into high interest topics for sixth graders. Grade 6 Claim 1 Item Slide Shows use these topics in a presentation with math practice problems. The questions require applying knowledge of algebraic...

Why does one person need 58 peaches; isn't that a bit excessive? This classic math dilemma offers pupils a chance to turn a word problem into an algebraic equation. Grade 6 Claim 1 Item Slide Shows includes this problem as part of a...

What are constraints and how can they be represented mathematically? This instructional slideshow provides an explanation and an example of how to translate constraints into algebraic inequalities.

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

Communication is the key. A presentation provides 25 sample items for Claim 3, Communicating Reasoning, for the Smarter Balanced High School Math assessment. Items require pupils to answer the question and provide logical reasoning to...
