Trade vs Squeebles Flip Multiplication

Trade-First Subtraction helps students learn and practice the trade-first subtraction method step by step. The app presents subtraction visually, with the numbers aligned automatically so students can focus on the operations in each column. Students can solve randomly generated problems or enter their own subtraction problems, and the number of digits can be adjusted for different skill levels. The Trade-First Method Trade-first subtraction is similar to traditional column subtraction, but the regrouping is completed before the subtraction begins. The method has two stages: * First, all necessary trading, regrouping, or borrowing is completed * Then, the subtraction in each column is solved This gives the method its name: trade-first. Regrouping is animated step by step so students can see what happens. Regrouping across several columns is also supported. Easy to Use After the student solves the operation for each column, the correct answer moves into the right place. If the student presses the wrong button, the answer appears above the keyboard but does not move. Features: * Numbers with 2–5 digits * Randomly generated or manually entered problems * Step-by-step trade-first subtraction practice * Animated regrouping * Supports regrouping across several columns * Current operation for each column can be hidden * Operands of the current operation can be highlighted * Customizable interface colors * Adjustable animation speed * Column separator lines can be hidden Teacher Endorsement: “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.” — Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada Other iDevBooks Math Apps: Other iDevBooks math apps include Column Addition, Long Multiplication, Long Division, Column Subtraction, Visual Multiplication Table, Partial Differences Subtraction, Partial Products Multiplication, Partial Sums Addition, Decimal Rounding, and more.

The Squeebles are back, helping you learn your times tables in a unique new way, in Flip Multiplication, an app designed and developed in conjunction with UK head teacher Ian Wilson and St. Margaret's Lee Primary School in London. Discover how to simplify the process of learning times tables by encouraging children to "flip" the question if they aren't sure of the answer straight away. They may know that 7 x 5 equals 35, but when faced with 5 x 7, they struggle. By understanding that those two questions are asking the same thing, children can move forward quickly with not only learning their times tables, but also understanding how multiplication works, cutting the number of tables they have to "learn" almost in half. This app can be used as a standalone method for learning tables or in conjunction with the more traditional method of learning the tables in their "sets". The tables are split into six, manageable, colour-coded levels, each one progressively slightly more challenging than the last. To pass a level, your child must not only answer all the included tables correctly in practice, but also prove they know them in a timed test. Questions from previous levels are also included in tests so that they aren't forgotten as progress is made through the app. A tables grid that shows the levels and each child's progress through them is available for reference and a "Flip" button for each question gives children the chance to see how flipping a table works. If they don't know the answer straight away, they can flip the question and see if that helps them. A great reward system and fun mini-game keeps children motivated, with 35 completely new Squeebles characters to collect as they work their way through the app. The mini game provides a welcome "brain break" but can only be used if enough work has been done in the educational part of the app. Parents and teachers can customise the app so the pass mark and required time for each level is set on an individual per-child basis and full reporting of progress is available for each child. An unlimited number of children can be registered with the app. As with all our apps, there are no in-app purchases, no adverts and no links to the internet of any kind.
