Deepen the number sense of your math class with a short presentation on writing equations. Using the relationship between numbers, young mathematicians learn how to determine the missing operator in an equation. A number of opportunities...

Learners investigate matrices by exploring addition, subtraction and multiplication of matrices.  Learners find the determinant and inverse of a matrix.  The lesson includes a set of practice problems

Investigate the relationship between addition and subtraction as scholars fill in these number sentences, each of which is missing a symbol. Is it a subtraction or addition equation? There are 20 of these to start, all written...

Try a new approach to addition and subtraction by giving scholars the numbers but leaving out the sign. They must determine if the numbers have been added or subtracted, then write in the appropriate operation. There are a few examples...

In this integers instructional activity, students solve and complete 8 various types of word problems. First, they read each problem and determine from the information what they are looking for. Then, students determine the operations...

Fourth graders examine the relationship between multiplication and division and subtraction and division, and determine which operation is needed to solve various problems. They observe and participate in a teacher-led lecture, and...

In this order of operations worksheet, students read an explanation of the order of operations and are taught to use the acronyms BODMAS and BIDMAS to solve these types of problems. Students then answer 45 questions in which they must...

Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another...

Develop an understanding of the Map, Keep, and Combine operations. The lab leads the class through the exploration of three list operations. Each task contains a self-check to measure scholars' understanding of the operation in the...

For this algebra worksheet, students read an algebraic expression and determine which of the options is the correct solution set for the expression. There are 5 problems on this worksheet.

What does order of operations have to do with solving equations? A video explains solving two-step equations using a do/undo chart. Learners recognize the operations within an equation and use inverse operations to undo those...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Number patterns can seem mysterious. Help your learners unravel these mysteries as they complete an intriguing task. Through examination, collaborative groups determine that they are able to produce all integers above a certain...

Need a less abstract approach to introducing extraneous solutions? This is it! Young mathematicians explore properties used to solve equations and determine which operations maintain the same solutions. They...

Each slide contains a group of animals and an equation that adds up to 10. However each equation is missing a number, learners attempt to determine the missing addend to revile the number of animals hiding under the cloud. A fun,...

Are exponent rules different if the exponents are negative? Using the definition of negative exponents and the rules of exponents, the resource shows that the rules of exponents hold independent of the sign of the exponent. Practice...

It's an ocean rescue mission! Groups must find a pilot downed off the coast of the Chesapeake Bay. Rescuers must determine the distance needed to travel as well as the heading to get to the pilot's last known position. Taking...

There's no need to roll dice for this probability experiment, the resource includes them already. Scholars use an interactive to see how including more possibilities as favorable outcomes in a dice activity affects the probabilities....

Pupils see how to solve math problems using place value. After watching an episode from Cyberchase, kids work together using hands-on materials to solve the problems given. This outstanding, ten-page lesson has everything you need to...

Reverse the wrapping to get to the gift. Using the idea of unwrapping a gift, the instructional activity introduces the concept of inverses. Pupils first determine the order needed to evaluate a function at a point, then use the reverse...

Apply properties of operations to work with mixed numbers. The first of two lesson plans that focus on properties of operations works with mixed numbers and converting opposites of sums. Pupils work with properties of operations to break...
