Place Value, Multiplication, Division
This document provides information and resources about teaching place value, multiplication, division, and other number sense concepts using the Power of Ten approach. It includes learning objectives, teaching strategies, and links to video examples for concepts like representing numbers, comparing quantities, skip-counting, using arrays and distributive property for multiplication, and modeling division using grouping or sharing scenarios. Suggestions are given for developing an understanding of factors and multiples through meaningful activities rather than rote memorization of tables.
Multiplication
Multiplication is an operation that involves adding a number to itself multiple times to find the total. It provides an efficient way to add the same number repeatedly. The factors are the numbers being multiplied, the product is the answer, and the formula shows that the number of groups multiplied by the number in each group equals the total. An example problem asks how many smiley faces there are if there are 2 groups with 4 smiley faces in each group.

1x1 Guru's novel way for teaching multiplication tables:
Utilizing cutting-edge educational technology to master the multiplication tables. Children may learn the multiplication tables effortlessly, independently, and with a lot of fun by using mental imagery.
It is an original and cutting-edge teaching strategy that revolutionizes the laborious study of multiplications. The child gains enormous self-confidence as math, and particularly the 1x1, is made to seem like an easy pastime.
The toddler also picks up mental arithmetic quickly.
This course has fantastic conversion rates and does well with parents and educators.

Pyramid Printing Company publishes magazines, catalogs, and retail.docx
Pyramid Printing Company publishes magazines, catalogs, and retail inserts for distribution in large metropolitan-area newspapers. Its largest customer is the New York News Company, for which Pyramid prints sales fliers and coupon inserts.
Pyramid has contractual agreements with its customers; its present pricing strategy is cost-plus, and customers also agree to a yearly price escalation based on inflation. Pyramid completes the escalation based on cost-of-operations increases.
Recently, Obelisk Publishing proposed a bid to the New York News Company for alternative pricing to counter Pyramid Printing’s contract, which will be up for renewal. To compete with the bid from Obelisk, Pyramid will have to employ target costing.
For this discussion:
· What are the differences between cost-plus and target-costing approaches to developing appropriate pricing? Give advantages and disadvantages of each.
· Are there elements of the value chain that Pyramid may leverage in order to optimize target costing for a mature customer relationship?

Instructional Software Education Technology
There are several types of software used in schools:
Instructional software is designed to teach skills or information through demonstration, examples, and problem solving. Tutorial software guides users through new concepts with pre-tests, post-tests, and drill and practice. Drill and practice software allows students to work independently and receive feedback on exercises. Simulation software provides realistic scenarios to involve students and save resources, while making experiments safe. Instructional games motivate learning through challenge, competition, and different difficulty levels. Problem solving software fosters those skills through various content-related problems. Special needs software assists students with disabilities through tools like speech synthesis and enlarged tests.

The Evolution and Impact of OTT Platforms: A Deep Dive into the Future of Ent...
This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.
