Partial Sums Addition vs Hands

Partial Sums Addition helps students learn and practice the partial sums addition method step by step. The app gives students a visual way to add numbers by working with each place value separately. The partial sums are then combined to find the final answer. Students can solve randomly generated problems or enter their own addition problems. The number of digits can be adjusted for different skill levels. The Partial Sums Method: In the partial sums method, each place value is added separately from left to right. For example, in 764 + 340, the partial sums are 1000, 100, and 4. These are then added together to get the final answer: 1104. Wired.com: “Esa Helttula’s apps are all fantastic for math learning and practice, and aren’t cluttered with mini-games, incentives, or annoying music.” 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.” — R. Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada Easy to Use: The numbers are aligned automatically so students can focus on solving each column. 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: - Step-by-step partial sums addition practice - Add 2 or 3 numbers - Each number can have 2–3 digits - Randomly generated or manually entered problems - Current operation for each column can be hidden - Operands of the current operation can be highlighted - Customizable interface colors - Adjustable animation speed - Custom interfaces for iPhone and iPad 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 Quotients Division, Decimal Rounding, and more. Feedback: New ideas to make this app better are welcome. Please visit idevbooks.com to give feedback. Privacy: This app has no ads, no in-app purchases, and does not transmit user data during operation. The app also does not contain links to other apps or to the web.

Hands-On Equations® Level 2 Continue the Fun Way to Learn Algebra! You've mastered the fundamentals. Now it's time for the next exciting step in your algebra journey! Hands-On Equations® Level 2 introduces an innovative new game piece—the white pawn, which represents the opposite of x. Using the white pawn together with the familiar blue pawn and numbered cubes, students learn elegant new strategies for solving increasingly sophisticated equations. Watch students confidently solve equations such as: 3x = –x + 4 and x – 3(–x) + 2 = 8 – 2x while enjoying the same highly visual, intuitive approach that has helped more than one million students better understand algebra. Discover More Advanced Algebra Naturally As students solve increasingly challenging equations, they intuitively apply important mathematical ideas, including: • Additive inverses • The additive property of zero • The addition property of equality As they solve these Level 2 equations, students discover how to add positive and negative numbers—without formal instruction. Rather than memorizing procedures, students develop a genuine understanding of why algebra works. Who Should Use Level 2? Hands-On Equations Level 2 is the natural continuation for students who have completed Level 1, including: • Gifted students in Grades 2 and above • Elementary students in Grades 4 and above • Middle school students • High school students who would benefit from a clearer, more visual approach to algebra • Adults who wish they had learned algebra this way the first time Experience Success. Build Confidence. As students experience continued success solving increasingly challenging equations, they develop greater confidence, deeper understanding, and an appreciation for the beauty and simplicity of algebra. If you enjoyed Hands-On Equations Level 1, you'll love discovering what you can accomplish in Level 2. For more information about Hands-On Equations, visit www.borenson.com.
