Base 10 Rounding

In this powers of ten learning exercise, 5th graders multiply and divide decimals by multiples of ten. They mentally solve simple problems containing powers of ten. This two-page learning exercise contains 10 problems.

Add visual representation to teaching place value with a magnitude model. Using adding machine tape, pupils build a linear place value strip from 1 to 100.

Pattern recognition is an essential step in the development of young mathematicians fluency with the four basic operations. This simple skills practice worksheet asks children identify and complete three different...

Youngsters respond to 10 problems that require them to calculate the products of the powers of 10 and write numbers in exponent form.

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps - though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Knowing mathematic terminology is vital for building a functional academic vocabulary. In this video, Sal defines number sets and the terms natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers....

Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using...

The instructor draws a diagram to represent a given value using base 10 blocks. She shows how to divide it up into groups just to give you a visual. She then demonstrates how to solve the problem using the long division method.

Powers of 10 are about moving the decimal around. The instructor illustrates how to move the decimal when it's ten percent or it's one percent. Once you understand this procedure you can do the mental math, in your head of course!
