Trade-First Subtraction vs Reading for Details I Kullanım & İstatistikleri

This app can be used to teach and study the trade-first subtraction method. The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings. The user can solve random subtraction problems with small and large numbers. The number of digits in the numbers can be set. Endorsed by Teachers Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada: "The math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice. Being able to adjust the level of difficulty to suit their needs is also very motivating for the students. I am so glad to have come across this great educational tool!" The Trade-First Method The trade-first subtraction method is similar to the traditional column subtraction method. The method has two stages. All of the "trading" or "borrowing" is done first. Then the subtractions are solved. This gives the method it's name, "trade-first." In the Everyday Mathematics curriculum the trade-first method is the focus algorithm for subtraction. The App is Easy to Use The numbers are aligned automatically so that you can concentrate on solving the operations for each column. Borrowing is animated step by step so you can see what happens. Borrowing over several columns is also supported. After you solve the operation for each column the correct answer will fly to the right place. If the user presses the wrong button the answer will appear above the keyboard but it will not move. Features: - Each number can have from 2 to 5 digits - Problems can be custom or random - The current operation for each column can be hidden - The operands of the current operation can be highlighted - Colors of the interface can be changed - The speed of the animations can be set - The lines separating the columns can be hidden Other iDevBooks math apps iDevBooks math apps have been reviewed and endorsed by Wired.com, IEAR.org, Edudemic.com, Teachers with Apps, and other respected sites and organizations.

This app has 26 stories about adventures, activities, nature, and human interests. All require careful reading to comprehend and recall details in order to answer the comprehension questions that follow. The student is asked to determine the main idea of the story, answer some questions that rely on details in the story, and make an inference that is supported by the details. Each question has a written explanation as to why the correct answer is correct and the other answers are incorrect. At the end of the question section of each story, there is an open-ended question for discussion. The Reading for Details series of apps were designed for individuals who need extra practice with reading comprehension. Their focus is on learning how to recall specific details of the stories. They are also appropriate for children and adults with traumatic brain injuries or stroke. Ideally, the student will work with a parent, teacher, or therapist while using the app. The mentor can guide the student’s reading strategies while using the app as a source of stories and questions. Reading for Details: Stories for Early Reading is the simplest of the series. The vocabulary and sentence structure are appropriate for early readers or children who are having difficulty with complex stories. Reading for Details I has short sentences with words that are are appropriate for 1st—3rd grade readers. Paragraphs are usually short. Sentence structure is simple and information is directly stated. Stories generally have between 350 and 400 words. Reading for Details II has stories written by authors from around the world and a vocabulary that should be familiar to 4th—6th grade students. Words and idiomatic phrases from other cultures are often used and defined in the stories. This adds an element of cultural diversity and allows the reader to see events from another's perspective. Reading Strategy: As the students read the stories, they should focus on the details of the story. At the end of the story, they should pause and decide what the story was mostly about. The first question asks them to identify the main idea of the story. Then there are two questions about details in the story. These are often of the form, How Many, Who, Which, or Where. There are no trick questions in the app but sometimes the answers contain details from the story that are not relevant to the question. These foils are intentionally placed to make sure the reader is reading for information and not just using recognition memory to answer the question. Students often get a question wrong because they focus on a specific detail. Sometimes they recognize words or numbers in the answers and choose an answer because the words are familiar. A popup explains why incorrect answers may appear to be correct. It also explains why the correct answer is, in fact, the right choice. After the student studies the explanation, they should read the question again and answer it using the knowledge gained from the explanation. They can swipe back to the story, reread it, and look for the answer. An option lets them choose to see the explanations after each answer, rather than just after incorrect answers. The last question requires that the student make inferences about the characters in the story. Based on the details and overall theme of the story, the student is asked to guess which of four statements is likely to be true. After the student answers, a popup explains why one answer is probably correct and the others are not as likely to be correct. Like the other questions, one answer is usually obviously incorrect. Two answers usually have have details from the story but are less likely to be true. The stories can be read in any order, but we have provided a default order based on complexity, vocabulary, and number of details. The app scores correct and incorrect answers and keeps track of the questions that were answered incorrectly. Results can be emailed or downloaded using iTunes.
