Integer Subtraction

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate simple sums.

Just because one integer is larger than another doesn't mean it will make sense right away. Go beyond note taking and show learners, through the use of algebra tiles and a Four-Pan Algebra Balance, how the numbers relate to one another...

Think, question, brainstorm, and make your way through a newsletter full of puzzles and word problems. The resource includes 10 different newsletters, all with interesting problems, to give class members an out-of-the box math experience. 

They could go all, the, way...to a deeper understanding of integers with this fun math game. Using the included printable materials, young mathematicians practice adding integers and calculating absolute values as they compete in a game...

In order to subtract mixed numbers, sometimes one may need to determine the least common multiple in order to find a common denominator. This is just what Sal does in this presentation. First, he shows how to find a common denominator...

To subtract two polynomials Sal demonstrates that you add the opposite of the second term, and then combine like terms to solve. How do you find an opposite term? Simply multiply the polynomial by -1. This video is very clearly explained...

Rational expressions that are in the form of fractions. Yuk! The teacher demonstrates how to subtract one rational expression from the other when the expressions have a common denominator. Combine like terms and write it in simplest form.

The rate of change is defined as how one quantity changes in relationship to another quantity. The instructor diagrams a graph and demonstrates how to use a formula to calculate the rate of change. It might take two viewings to catch all...

Eliminate young mathematicians' confusion over performing operations with integers using this set of classroom displays. Providing learners with simple, easy-to-follow rules, this resource will have students fluently adding, subtracting,...
