Equivalent, simplifyng and comparing fractionsgrade5a
Equivalent, Simplifying and Comparing Fractions. There are three main topics covered: 1) Equivalent fractions are two fractions that have the same value but different numerators and denominators. 2) Simplifying fractions involves dividing or multiplying the numerators and denominators to get a reduced form. 3) Comparing fractions involves determining if they have the same or different denominators. Fractions with the same denominator are compared by their numerators, while those with different denominators require finding a common denominator first.
This document provides an overview of basic math terminology and operations that are important to know for the ACT exam. It defines terms like real numbers, rational numbers, integers, even/odd numbers, prime numbers, and radicals. It also reviews basic operations like exponents, multiplying/dividing numbers with exponents, and rules of divisibility. The document emphasizes knowing these fundamental concepts as many partial answers rely on interpreting terms correctly. A strong foundation in math basics and terminology is key to solving problems on the ACT.
The document outlines the daily objectives and agenda for a math class focusing on fractions. It includes: completing a real-world math problem involving fractions; getting into small groups to discuss homework on adding and subtracting fractions; taking notes on the rules and examples for adding and subtracting fractions; and practicing word problems involving fractions.
This document provides a lesson plan on using triangle congruence to construct perpendicular lines and angle bisectors.

The document outlines the objectives and schedule for a summer school geometry class. Module 1 will cover plotting points on the Cartesian coordinate plane and determining if points lie on lines. Module 2 will introduce the undefined terms of point, line and plane and how to correctly notate them to build geometry vocabulary. The class will have module assessments every day with a 3 absence limit and cover topics like naming points and lines, planes, and building additional geometry terms.
This document provides a lesson on combining like terms in algebra. It defines like terms as expressions with the same variable and exponent parts. It gives examples of like and unlike terms and explains that the coefficient of a term is the number in front of the variable or is understood to be 1 if there is no expressed number. The steps to combine like terms are identified as: 1) identify terms with the same variable and exponent, 2) group the like terms, and 3) combine the terms by adding or subtracting the coefficients. An example problem is worked through as 9a^2 - 6a - 11a^2 + 10a = -2a^2 + 4a.
Adding and subtracting fractions with like denominators lesson planjkrutowskis
The document provides an outline for a lesson on adding and subtracting fractions with like denominators. It includes an opening activity to review fraction equations, modeling addition and subtraction of fractions, guided practice with fraction problems and notes, independent practice with word problems, and an exit ticket asking students to explain how to add or subtract fractions to their parents. Key vocabulary and strategies like common denominators and simplifying are discussed.
This document discusses absolute value and its uses. It begins with examples of absolute value as the distance between numbers and zero on the number line. Students then work through exercises calculating absolute values and using absolute value to find the magnitude, or size, of quantities in real-world contexts like temperatures, debts, and weights. The document ensures students understand that absolute value is never negative, as it represents distance or magnitude. It poses discussion questions at the end to check understanding of key absolute value concepts.
