This lesson has a number of fun worksheets for a pre-algebra or beginning algebra class. The main emphasis of this lesson is functions, formulas, and looking at square roots. It is the third lesson in a series on solving for unknowns, which you can find if you look first at the "Getting Started" link. This lesson, in particular, focuses on developing an understanding between the inverse relationship of squaring a number and taking its square root, finding probabilities, and creating linear equations and solving problems.
Does a calculator give you the exact value of the square root of 2? Here, learners must decide if 1.414236 is equal to the square root of 2. They must also explain why the square root of 2 could never be equal to a terminating decimal. Learners must be familiar with rational and irrational numbers before beginning.
Use this lesson to help your pupils read, write, model, order, and define scientific notation, square roots, and powers. They define key vocabulary terms, observe and demonstrate how to write out powers, square roots, and numbers in scientific notation, and complete a worksheet.
There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two known square roots and either side of the unknown root. From there, let your number crunchers decide how they want to proceed. Using a calculator will not take away from the objective.
A great resource for any math teacher covering multiples, factors or square roots; this worksheet walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually increase in their level of difficulty and abstraction. Problem solving. multiple choice and word problems are intermixed with mathematical rules, definitions and fun facts to create a thorough and engaging activity. This worksheet also includes a brief extension section
Eighth graders discover the steps necessary to approximate the square roots of numbers that are not perfect squares. There are all sorts of support worksheets embedded in the plan, and some websites for your class to access to further practice by engaging with interactive math programs. An outstanding resource that combines technology with old-fashioned teaching!
Introducing square roots into the quadratic equation mix, Sal takes care to address the ways viewers might go about solving the problems, both correctly and incorrectly. The video is an integral step in not only Sal's algebra series, but also in a developing math education.
Though Sal expects that viewers are "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation, and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to illustrate the relationship between square roots and parabolas, and how to translate the equations to different graphs.
Students find patterns relating the lengths of the sides of squares to their areas. In this squares and square roots lesson, students draw squares and find their areas. They estimate the sides of square when given the area. Students use the Pythagorean Theorem to check their work. The culminating assignment, requires students to write a short paper about squares.
In this square roots worksheet, 8th graders solve 14 different types of problems to include determining the square root of a number of problems, determining the area of a rectangle and the length of a side of a square with the same rectangle. They also determine the length of each unknown side of the illustrated right-angled triangles and then, find the length of a diagonal of each rectangle. Finally, students determine the value of problems and write their answer in fraction form.
Seventh graders read, write, model, and order scientific notation, square roots, and powers. They define and discuss key vocabulary terms, observe the teacher model examples of each term, and independently write and read numbers, compare number values, and order numbers.
What is the square root of 100? Sal explains what the square root of 100 is, but he needs a little help explaining why. Note: This concept can be challenging for some. If you are showing this video to your class, it does not stand alone. Teacher facilitation will be needed.
In this roots and the Pythagorean Theorem worksheet, learners solve 15 different types of problems related to square roots and applying the Pythagorean Theorem. They first determine the square root of each number and then, the cube root. Pupils also determine the length of each unknown side in the illustrations shown and determine the sets of numbers that can be the lengths of the sides of a right triangle.
