Numbers that are written in scientific notation can be multiplied directly by using properties of exponents. Unlike adding and subtracting with scientific notation, the powers of 10 do not need to be alike to multiply. The powers of 10 can differ. We walk-through two problems of multiplying scientific notation with positive powers of 10, and one problem with negative powers of 10. First we multiply the multiplicands, then add the exponents of the powers of 10. When adding negative exponents, remember to follow the rules for integer addition. 8th Grade Math 2.4a, Adding and Subtracting with Scientific Notation https://youtu.be/TtE1TEGMRbQ 8th Grade Math Course Playlist https://www.youtube.com/playlist?list=PLKi4WTp6PRGXnc3q2i4u3GMqVHYBFMz56 This video and its contents are the property of JoAnn's School and is protected under U.S. copyright law.

Why Three-dimensional shapes are called 3-D shapes, cubes, spheres, rectangular prisms, cones, and cylinders. Length, width, and height are explained, matching 3D shapes to their two-dimensional flat surfaces, identifying everyday objects as 3D shapes, identifying which 3D shape has a flat surface, sorting shapes by their corners, faces, and curves.

We can write some fractions as percents by writing an equivalent fraction with a denominator of 100. This method is useful when the fraction has a denominator that is a factor or a multiple of 100. If a fraction does NOT have a denominator that is a factor or multiple of 100, we can use long division. Sometimes when we use long division, the digits of a decimal will repeat. We can write a bar over all of the digits that repeat. We solve three word problems that involve writing fractions as decimals and percents.

We can multiply a decimal and a whole number by using the Distributive Property to find partial products and their sum. We can use place value to multiply the digits as if they were all whole numbers, then count the decimal places (hops) in the factors for the amount of decimal places (hops) in the product. We review using quick drawings to multiply decimals. To use place value patterns, we multiply the decimal digits as if they are whole numbers. Then we count all decimal places in the factors (hops). The total amount of decimal places (hops) in the factors will be the amount of decimal places (hops) in the product. We discuss how we will know a product will be greater or less than a whole number factor. When we multiply a decimal by 100, the decimal point moves two places to the right. Then if we multiply that product by 0.01, the decimal point moves two places to the left. We will have the original factor. So multiplying by 100 is the same as dividing by 100. We show how to write a decimal equation in vertical form when it is given in sentence form. We review how adding or removing trailing zeros from the right side of a decimal will not change its value. We solve two word problems involving multiplication with decimals and whole numbers. 5th Grade Math 1.3, Properties of Addition and Multiplication, Mental Math https://youtu.be/LpqwYAKBlww 5th Grade Math 3.4, Round Decimals Using Place Value or Place-value Chart https://youtu.be/y-qf_h_LmY0 5th Grade Math 4.1, Multiplication Patterns with Decimals https://youtu.be/zJfx7I4_zfI 5th Grade Math 4.2, Model Multiplying Decimals by Whole Numbers https://youtu.be/JSRU83Dqr5o 5th Grade Math Playlist https://www.youtube.com/playlist?list=PLKi4WTp6PRGX8NtQpzliTlMceQT1ua24f I'm using the Houghton Mifflin Go Math! 2015 copyright textbook for this playlist.
