K-12 Curriculum Guide in Math III
This document outlines the K to 12 curriculum guide for mathematics III. It includes 18 performance standards covering a range of math concepts from numbers and operations to measurement, geometry, patterns, and data analysis. It also provides examples of strategies and games to help students learn the concepts, including number hunt scavenger games, a "Go Fish" card game focused on addition facts, an activity practicing money skills, and a card game for learning division skills.
3 digit addition
This document discusses 3 digit addition by first writing the problem in expanded form by placing the numbers in columns of hundreds, tens, and ones. It then represents the addition using base 10 blocks by stacking the blocks in columns. The document notes that regrouping may be required when adding 3 digit numbers.
Regrouping + and
This document provides instructions for adding and subtracting multi-digit numbers. It explains that when adding, you start with the ones place and regroup/carry numbers to the next column if needed when adding in that place. For subtraction, you may need to borrow from the next column over if the number you are subtracting is larger than the number in that column, and then regroup those borrowed tens as ones in the ones column. Examples of adding 326 + 179 and subtracting 642 - 387 are provided to demonstrate the processes.
Spoken english
The document discusses English language training services provided by 3DOT Technology. They offer conversation practice with native English teachers to help students improve their speaking skills within 3 weeks without focusing on boring grammar lessons. 3DOT also provides certified training in innovative teaching methods and e-learning to develop professional skills at an affordable cost.
Vedic addition
Vedic Mathematics is a system of mathematics that allows problems to be solved quickly and efficiently. It is based on the work of Sri Bharathi Krishna Thirthaji Maharaja (1884 – 1964), who devised the system from a close study of the Vedas. The Vedas are ancient scriptures of India that deal with many subjects. It is based on 16 sutras (aphorisms) from the Vedas that provide a principle or a rule of working to solve a problem. These sutras may be ancient in origin, but are still relevant to modern day mathematics.
Presentation melvin b. atole
The document appears to be a quiz for elementary school students in the Philippines covering topics such as linking verbs, alphabets/baybayin, marsupial mammals, and coloring pictures related to water. It asks students to identify whether "is" is a linking verb, if a provided image is an alphabet or baybayin script, to select which picture shows a marsupial mammal, and to color a picture blue if it depicts water. The quiz seems designed to test students' knowledge of English grammar, Philippine history, zoology, and the ability to follow basic instructions.
Grade 5 band Open House
The document summarizes the goals and activities of the Grade 5 band program at SAS Puxi Elementary. The program aims to strengthen music skills and ensemble playing through developing techniques like sight reading, music theory, and balance. Students will perform at winter and spring concerts and have opportunities for private lessons and field trips. Expectations include practicing, being on time, and maintaining instruments. The calendar outlines units and performances for the year.

Positive integers increase as you move to the right of zero on a number line, while negative integers decrease as you move left. The document also presents two methods for adding integers: using a number line by moving left and right, and using the absolute value of numbers and subtraction.
Infinitives PowerPoint
Infinitives can act as nouns, adjectives, or adverbs. As nouns, infinitives can serve as subjects, direct objects, or predicate nominatives. As adjectives, infinitives modify nouns or pronouns. As adverbs, infinitives modify verbs, adjectives, or other adverbs. Infinitives are verbals that take the form of "to + base verb" and can function as different parts of speech within sentences.

Grouping Symbols
The document discusses punctuation used in math expressions. Punctuation marks called grouping symbols are used in math to give meaning to expressions, including parentheses, brackets, braces, and the division bar. For example, parentheses tell you to calculate what is inside them first before doing anything else in an expression. Brackets and braces are used instead of parentheses in complicated expressions to make them easier to read. The division bar indicates to evaluate the numerator and denominator of a fraction separately.
Basic Grammar
This document introduces some basic grammar concepts in mathematics, including nouns, adjectives, verbs, and sentences. It explains that in mathematics, nouns refer to expressions, which are combinations of numbers, variables, operations, and symbols. Variables are classified as common nouns, while specific numbers are classified as proper nouns. Sentences in mathematics relate expressions using simple verbs like equals, less than, and greater than to form equations and inequalities. Compound sentences can be formed by combining simple sentences with verbs like and and or.
Addition Algorithm
The document outlines a 3-step algorithm for adding integers:
1) Determine if the integers have the same or opposite signs.
2) If same, use the common sign. If opposite, use the sign of the integer with the larger magnitude.
3) If same, add the magnitudes. If opposite, subtract the smaller magnitude from the larger.
It then provides examples and discusses adding multiple integers by first adding all positives, all negatives, and then combining the results.
Multiplication Algorithm
The document discusses the integers multiplication algorithm. It states that the product of an even number of negative numbers is positive, while the product of an odd number of negative numbers is negative. To determine the sign and magnitude of the product of signed numbers, one should first determine if the number of negative numbers is even or odd, write down the sign if it is negative, and then compute the magnitude by multiplying the absolute values of the numbers.
Definitions
The document defines integers and their properties. Integers include positive numbers like 1, 2, 3, and their opposites -1, -2, -3, called negative numbers, as well as zero. The integers follow rules like -(-3) = 3, and for any integer n, n + -n = 0. Integers can be visualized on a number line with equally spaced points labeled with numbers, showing their relative positions and how they increase or decrease in the positive direction.
